Do dogs need heartworm medicine in winter? Lets unpack this.

Do dogs need heartworm medicine in the winter sets the stage for this enthralling narrative, offering readers a glimpse into a story that is rich in detail with creative and humorous language style and brimming with originality from the outset.

Ah, winter! A time for cozy sweaters, perhaps a snowflake or two, and definitely a moment to ponder if Fido’s monthly preventative still reigns supreme. While the frosty air might lull us into a false sense of security, the tiny heartworm parasite, with its ingenious life cycle, doesn’t exactly pack its bags for a tropical vacation when the temperature drops.

This isn’t just about chasing away a few pesky mosquitoes; it’s a deep dive into the sneaky ways heartworms operate and why your furry companion might still be in their crosshairs, even when the world is covered in a blanket of white.

Understanding Heartworm Transmission Seasonality

Heartworm disease, a serious and potentially fatal condition for dogs, is transmitted through the bite of infected mosquitoes. While often associated with warmer months, understanding the nuances of heartworm transmission seasonality is crucial for effective prevention, even during winter. This involves delving into the parasite’s life cycle, the role of its vector, and the environmental factors that influence transmission.The life cycle of the heartworm parasite, Dirofilaria immitis, is complex and intricately linked to its mosquito host.

It begins when an adult female heartworm residing in an infected dog produces microfilariae, which are microscopic larval stages. These microfilariae circulate in the dog’s bloodstream.

The Role of Mosquitoes in Heartworm Transmission

Mosquitoes become infected when they take a blood meal from an infected dog, ingesting the microfilariae. Inside the mosquito, these microfilariae undergo development into infective larvae over a period of about 10 to 14 days. The specific development time is influenced by ambient temperature. Once these infective larvae mature, they migrate to the mosquito’s salivary glands, ready to be transmitted to another host.

When an infected mosquito bites a susceptible dog, it injects these infective larvae into the dog’s skin, initiating the cycle anew.

Geographical and Seasonal Variations in Mosquito Activity

The geographical location and prevailing climate significantly impact mosquito populations and, consequently, heartworm transmission risk. In tropical and subtropical regions, mosquitoes can be active year-round, posing a constant threat of heartworm transmission. However, in temperate climates, mosquito activity is largely seasonal, diminishing considerably or ceasing altogether during colder months.

Typical Months of Mosquito Prevalence in Temperate Climates

In temperate climates, such as much of North America and Europe, mosquitoes are typically most prevalent and pose the greatest risk of heartworm transmission during the warmer months. This period generally spans from late spring through early autumn.The peak months for mosquito activity, and therefore the highest risk of heartworm transmission, usually occur between:

• May and October in many parts of the Northern Hemisphere.
• April and November in areas with longer warm seasons.

It is important to note that even in regions with distinct winter seasons, a few hardy mosquito species may survive or become active on warmer winter days. Furthermore, the development of infective larvae within the mosquito requires a minimum ambient temperature, typically around 64°F (18°C), to occur. If temperatures remain below this threshold for an extended period, transmission is unlikely.

“Understanding the temperature-dependent development of heartworm larvae within mosquitoes is key to assessing year-round risk, even in colder climates.”

The Impact of Winter on Heartworm Development

While the mosquito’s role as the intermediate host is crucial for the initial development of heartworm larvae, the onset of winter introduces significant environmental challenges that directly influence the parasite’s lifecycle and transmission potential. Understanding these effects is key to assessing the necessity of year-round heartworm prevention.

Larval Development and Temperature Sensitivity

The development of heartworm larvae within mosquitoes, a process known as the pre-patent period, is highly dependent on ambient temperature. Mosquitoes must ingest blood containing microfilariae (the larval stage of the heartworm) from an infected animal. Once inside the mosquito, these microfilariae mature into infective larvae. This maturation process requires specific temperature thresholds to occur.Temperatures below a certain point can halt or significantly slow down this development.

For instance, if the average daily temperature remains below 64°F (18°C), the larvae are unlikely to progress to the infective stage within the mosquito’s lifespan. Warmer temperatures accelerate this development, with optimal conditions often cited between 70°F and 85°F (21°C to 29°C). This temperature dependency means that in colder climates, the period during which mosquitoes can transmit heartworm is naturally limited.

Larval Survival in Cold Weather

The survival rate of heartworm larvae, particularly the infective stage, in cold weather conditions is considerably reduced. When temperatures drop significantly, especially to freezing levels, the larvae within mosquitoes are often killed. While some adult mosquitoes might survive cold snaps by entering a state of dormancy or seeking sheltered locations, the parasites they carry are vulnerable.

Freezing temperatures are generally lethal to the infective larval stages of the heartworm parasite within the mosquito.

Even if mosquitoes survive, the microfilariae and developing larvae inside them face a much lower chance of reaching the infective stage and subsequently being transmitted to a dog. This natural interruption in the transmission cycle is a primary reason why heartworm prevalence often declines in regions with harsh winters.

Adult Heartworm Survival in Dogs During Winter

The survival of adult heartworms within a dog’s circulatory system is not directly impacted by the external winter temperatures. Adult heartworms reside in the heart, lungs, and associated blood vessels of the definitive host, the dog. Their survival is dependent on the dog’s physiological environment, not the ambient weather.

Once a dog is infected with adult heartworms, these parasites can live for several years within the animal, regardless of the season.

Therefore, a dog infected in the warmer months will continue to harbor adult heartworms throughout the winter. This is a critical point, as these adult worms continue to produce microfilariae, which can then be picked up by any mosquitoes that become active during warmer periods, even if those periods are brief or occur during winter in milder climates.

Impact of Freezing Temperatures on Infective Larvae

Freezing temperatures have a detrimental effect on the infective stage of the heartworm parasite, Dirofilaria immitis. The infective larvae, known as third-stage larvae (L3), are what are transmitted to dogs through mosquito bites. These larvae are metabolically active and require a certain temperature range to survive and develop further once inside the dog.When exposed to freezing temperatures, either within the mosquito or in the environment if the mosquito dies, these L3 larvae are generally unable to withstand the extreme cold.

This effectively halts the transmission cycle by eliminating the viable infective stage. However, it is important to note that the survival of the parasite is a complex interplay of temperature, host availability, and the duration of exposure to cold. In areas where winters are not consistently freezing, or where there are intermittent warm spells, mosquitoes capable of transmitting heartworm may still exist, albeit for shorter periods.

Veterinary Recommendations for Winter Heartworm Prevention

Leading veterinary organizations worldwide, including the American Veterinary Medical Association (AVMA) and the Companion Animal Parasite Council (CAPC), strongly advocate for year-round heartworm medication for dogs. This recommendation is based on a comprehensive understanding of heartworm biology, transmission dynamics, and the potential for disease development even in colder months. The rationale behind this persistent approach is to provide continuous protection and mitigate the risks associated with intermittent prevention.The consistent administration of heartworm preventatives is crucial for several interconnected reasons.

While mosquito activity significantly decreases in winter, it does not always cease entirely, and the survival of infected mosquitoes can extend into cooler periods. Furthermore, the lifecycle of the heartworm parasite itself is a key consideration. Once an infected mosquito transmits larvae to a dog, these larvae undergo development within the dog’s body for several months before becoming adult worms capable of causing disease.

This developmental period means that a mosquito bite in late autumn could lead to a developing infection that persists through winter, even if no further mosquito exposure occurs.

Risks of Discontinuing Winter Preventative Medication

Stopping heartworm preventative medication during the winter months, even in regions with cold climates, exposes dogs to significant health risks. The primary danger is the potential for the development of heartworm disease from larvae transmitted in the preceding months. These larvae, injected by mosquitoes before the onset of winter, continue their maturation process within the dog’s body. If preventative medication is halted, these developing worms are not eliminated and can progress to adulthood, leading to serious cardiovascular damage.The consequences of heartworm disease are severe and can be irreversible.

Adult heartworms reside in the heart, lungs, and associated blood vessels, causing inflammation, blockages, and ultimately heart failure. Symptoms can range from mild coughing and fatigue to severe respiratory distress and sudden death. Treatment for heartworm disease is not only costly and time-consuming but also carries inherent risks for the dog. Therefore, preventing infection through continuous medication is far more effective and humane than treating the disease after it has taken hold.

“The most effective strategy for preventing heartworm disease is consistent, year-round administration of an approved heartworm preventative.”

Companion Animal Parasite Council (CAPC)

Efficacy of Preventatives in Varied Environmental Conditions

Heartworm preventatives are designed to target different stages of the heartworm lifecycle and are formulated for various administration methods, including oral pills, topical solutions, and injectable medications. The efficacy of these preventatives is generally high when used according to label instructions, regardless of environmental conditions. However, understanding how each type functions can inform optimal usage.For instance, oral and topical preventatives typically kill microfilariae (the larval stage circulating in the blood) and immature heartworm larvae shortly after infection.

Injectable preventatives, such as those containing moxidectin, offer a longer duration of action, providing protection for up to 12 months with a single dose. This extended protection is particularly beneficial in ensuring continuous coverage throughout the year, minimizing the chance of gaps in immunity.The effectiveness of any preventative relies heavily on owner compliance. Year-round administration ensures that even if a mosquito transmits larvae in a warm spell or an unseasonably mild winter day, the preventative will be present in the dog’s system to eliminate the infection before it can establish.

While mosquito activity may be reduced, the parasite’s lifecycle continues, and the risk, though lower, is not eliminated. Veterinary guidance is essential in selecting the most appropriate preventative based on the dog’s lifestyle, geographic location, and the specific parasite risks in the area.

Factors Influencing the Need for Winter Medication

The decision to continue heartworm medication for dogs throughout the winter months is not a one-size-fits-all answer. Several interconnected factors play a crucial role in determining the ongoing risk of heartworm transmission, making a nuanced approach essential for pet owners. Understanding these variables empowers owners to make informed decisions in collaboration with their veterinarians.The geographical location and the prevailing climate conditions are paramount in assessing the year-round risk of heartworm.

Different regions present varying levels of mosquito activity and survival rates, which directly correlates to the potential for heartworm transmission. Local environmental nuances can significantly alter the traditional understanding of seasonal disease transmission.

Climate Zones and Heartworm Risk

The risk of heartworm transmission in winter is heavily influenced by the specific climate zone a dog resides in. Generally, regions with consistently cold, freezing temperatures throughout the winter months pose a significantly lower risk of active heartworm transmission. Mosquitoes, the intermediate hosts for the heartworm parasite, cannot survive or reproduce in sub-zero conditions.In contrast, warmer climates or regions experiencing prolonged mild winters present a higher risk.

Even if temperatures dip below freezing occasionally, if mosquitoes can survive and remain active for extended periods, the transmission window remains open. This includes areas where winters are characterized by frequent thaws and refreezes, allowing mosquito populations to persist. For instance, southern states in the United States often experience mild winters with sufficient mosquito activity to warrant year-round prevention. Conversely, northern states with harsh, consistently cold winters might see a reduced need for continuous medication, though vigilance is still advised.

Environmental Factors and Mosquito Presence

Local environmental factors significantly impact mosquito populations, and consequently, the risk of heartworm transmission during winter. Prolonged mild winters, even in areas not typically considered warm, can create an extended season for mosquito activity. Factors contributing to this include:

• Consistent above-freezing temperatures for extended periods.
• Abundant standing water sources that may not freeze solid, providing breeding grounds for mosquitoes.
• Urban or suburban environments that may offer more sheltered microclimates or heat retention, allowing mosquitoes to survive.

Even a few weeks of sustained warmth can be enough for infected mosquitoes to transmit heartworm larvae to susceptible dogs. Therefore, observing local weather patterns and mosquito activity is a critical component of risk assessment.

Veterinary Consultation for Personalized Advice

The most critical factor in determining the necessity of winter heartworm medication is personalized advice from a veterinarian. Local veterinarians possess intimate knowledge of regional heartworm prevalence, mosquito vectors, and climatic patterns specific to their practice area. They can assess a dog’s individual risk based on several factors, including:

• The dog’s geographic location and its specific climate.
• The dog’s lifestyle, such as whether it spends significant time outdoors or travels to different regions.
• The prevalence of heartworm disease in the local animal population.
• The specific heartworm prevention medication being used and its efficacy against local strains.

Veterinarians will also consider the life cycle of the heartworm parasite and the efficacy of the chosen preventative in killing larvae before they mature, even if transmission occurs during colder months.

Scenarios for Potentially Discontinuing Winter Medication

While year-round prevention is often recommended, there are specific scenarios where a veterinarian might advise against continuing heartworm medication throughout the winter. These decisions are made on a case-by-case basis after a thorough assessment of the dog’s risk profile.A veterinarian might advise against year-round medication in the following situations:

• Consistently Freezing Climates: In regions where winter temperatures reliably remain below freezing for the entire duration of the season, effectively eliminating mosquito activity, the risk of transmission is negligible. This typically applies to areas with harsh, long winters where mosquitoes cannot survive.
• Documented Absence of Mosquitoes: If local entomological data or extensive observation confirms a complete and sustained absence of active mosquitoes throughout the winter months in a specific microclimate, the need for continuous medication may be re-evaluated. This is a rare scenario in many regions.
• Dogs with Known Sensitivities or Adverse Reactions: In rare cases, a dog might experience significant adverse reactions to heartworm medication. If the perceived risk of transmission is extremely low due to environmental factors, a veterinarian might discuss alternative strategies or temporary cessation of medication after careful risk-benefit analysis. However, this is typically a last resort.
• Dogs Primarily Living Indoors in Cold Climates: A dog that lives exclusively indoors in a region with very cold winters and has virtually no exposure to the outdoors, especially at dawn and dusk when mosquitoes are most active, might have a significantly reduced risk. However, even indoor dogs can be exposed if mosquitoes find their way inside.

It is crucial to understand that these scenarios are highly dependent on the specific geographic location and the veterinarian’s professional judgment. Any decision to alter or discontinue heartworm prevention should always be made in consultation with a veterinarian.

Consequences of Incomplete or Discontinued Prevention

Failing to maintain consistent heartworm medication, even during winter months, can expose your canine companion to severe health risks. Heartworm disease, if left untreated, progresses through distinct stages, each bringing escalating damage to the dog’s vital organs. Understanding these consequences is paramount for responsible pet ownership.The heartworm parasite, transmitted by infected mosquitoes, undergoes several developmental stages within the dog’s body.

If preventive medication is not administered continuously, these parasites can mature and begin to cause significant harm, leading to potentially irreversible damage and even death.

Potential Health Complications of Untreated Heartworm Infection

When heartworm larvae mature into adult worms within a dog’s heart and pulmonary arteries, they can cause a cascade of serious health issues. These complications affect the cardiovascular system, leading to a range of debilitating symptoms and, in severe cases, a fatal outcome.The adult heartworms, which can grow up to 12 inches long, obstruct blood flow and inflame the blood vessels.

This chronic inflammation and blockage lead to:

• Pulmonary hypertension, which is high blood pressure in the arteries of the lungs.
• Right-sided heart failure, where the heart’s right ventricle struggles to pump blood effectively to the lungs.
• Damage to the lungs, including coughing, difficulty breathing, and exercise intolerance.
• Liver and kidney damage due to reduced blood flow and the body’s inflammatory response.
• Blood clots forming in the pulmonary arteries, which can lead to sudden collapse and death.

Diagnostic Process for Heartworm Disease

Diagnosing heartworm disease involves a multi-faceted approach to accurately identify the presence of the parasite and assess the extent of the infection. Veterinarians utilize a combination of physical examinations, laboratory tests, and imaging techniques to arrive at a diagnosis.The initial step typically involves a thorough physical examination, where the veterinarian listens for abnormal heart and lung sounds, checks for weight loss, and assesses the dog’s overall condition.

This is followed by laboratory testing:

• Blood Tests: These are crucial for detecting heartworm antigens (proteins produced by adult female worms) and antibodies (produced by the dog’s immune system in response to the parasite). Antigen tests are generally considered more reliable for detecting infection in its early stages.
• Microfilaria Tests: These tests look for the presence of microscopic baby heartworms (microfilariae) in the blood. However, some dogs can be infected with adult worms but not have microfilariae in their blood, especially if they are on certain preventive medications that kill microfilariae but not adult worms.

Imaging techniques provide further insight:

• X-rays: Chest X-rays can reveal changes in the heart and lungs, such as enlargement of the heart’s right ventricle and thickened pulmonary arteries, indicative of heartworm disease.
• Echocardiogram (Ultrasound of the Heart): This advanced imaging technique allows veterinarians to visualize the heart’s structure and function, and in some cases, even see adult heartworms within the heart chambers and pulmonary arteries.

Treatment Protocols for Heartworm Infections

Treating heartworm disease is a complex and potentially risky process that requires strict veterinary supervision. The primary goal of treatment is to eliminate adult heartworms and prevent further complications. It is crucial to understand that treatment is not a simple pill and involves multiple stages.The treatment protocol typically involves several phases:

• Stabilization: Before starting the primary treatment, dogs may need to be stabilized if they are showing signs of heart failure or other severe symptoms. This can involve medications to manage fluid buildup, improve heart function, and reduce inflammation.
• Adulticide Therapy: This phase involves administering medications, usually injections of melarsomine dihydrochloride, to kill adult heartworms. This is typically done in two or three injections given over a period of time. The dog must be kept very quiet and restricted from strenuous activity during this period to minimize the risk of complications from dying worms.
• Microfilaricide Therapy: Once the adult worms are eliminated, medications are given to kill any remaining microfilariae in the bloodstream.
• Follow-up Testing: Several months after treatment, the dog will undergo further blood tests to confirm that all heartworms have been eliminated.

It is important to note that heartworm treatment can have side effects, including pain, lethargy, vomiting, and in rare cases, severe reactions such as pulmonary embolism. Therefore, close monitoring by a veterinarian throughout the treatment process is essential.

A Dog Experiencing Advanced Heartworm Disease

Imagine a once-energetic Golden Retriever named Buddy, now a shadow of his former self. His once bright eyes are dull, and his once wagging tail hangs low. Buddy’s owner had, unfortunately, discontinued his heartworm medication during a particularly cold winter, believing it was no longer necessary. Now, months later, Buddy struggles to breathe, his cough a persistent, hacking sound that punctuates the quiet of the house.

He tires after mere minutes of walking, his body unable to keep up with his spirit.His abdomen appears distended, a visible sign of fluid buildup in his chest and belly, a consequence of his failing heart. When he attempts to play, even a gentle game of fetch, he collapses, his breathing shallow and rapid. His gums are pale, indicating a lack of oxygen reaching his tissues.

Buddy’s veterinarian, upon examination, can hear a distinct murmur and crackling sounds in his lungs, clear indicators of severe cardiovascular and pulmonary damage. X-rays reveal a dramatically enlarged heart, particularly the right side, and constricted pulmonary arteries, a grim testament to the relentless invasion of heartworms. The diagnosis is advanced heartworm disease, a condition that has taken a devastating toll on Buddy’s once vibrant life.

Practical Considerations for Owners

Navigating heartworm prevention during winter requires careful planning and a clear understanding of the risks involved. This section addresses practical aspects for dog owners, aiming to demystify the process and highlight the importance of consistent vigilance.Ensuring your canine companion receives year-round protection against heartworm is not merely a recommendation but a crucial step in safeguarding their health. This involves understanding the practicalities of medication administration, dispelling common myths, and recognizing the long-term financial and health benefits of consistent prevention.

Even when Jack Frost nips at their noses, your furry friend might still need that heartworm prevention. It’s a bit like asking are all aloes medicinal ; not every plant has the same healing powers, and not every bug disappears in winter. So, to keep Fido’s heart beating strong, don’t ditch the meds just yet!

Administering Monthly Heartworm Medication

Consistent administration of heartworm medication is paramount to its efficacy. A reliable schedule ensures that the medication is present in your dog’s system at all times, effectively preventing the development of heartworm larvae into adult worms.Designing a simple yet effective monthly schedule can significantly reduce the chances of missed doses. This involves integrating the medication into your dog’s routine, making it a predictable and non-negotiable part of their care.

1. First Weekend of the Month: Designate the first weekend of each month as “Heartworm Medication Weekend.” For instance, if your dog takes their medication on Saturdays, this becomes a fixed point in your calendar.
2. Integrate with Other Routines: Pair the medication with a regular activity, such as a favorite walk, grooming session, or a special treat. This association can help both you and your dog remember the task.
3. Calendar Reminders: Utilize digital calendars or physical wall calendars to set recurring reminders for the medication day.
4. Note-Taking: Keep a small logbook or a note on your phone to tick off each dose administered. This provides a visual confirmation and helps track any accidental omissions.
5. Contingency Planning: If you anticipate being away or unable to administer the medication on the scheduled day, plan ahead. Administer it as soon as possible before or after the missed date, and consult your veterinarian if you are unsure about the timing.

Common Misconceptions About Winter Heartworm Prevention, Do dogs need heartworm medicine in the winter

Despite the prevalent belief that heartworm is a purely warm-weather threat, several misconceptions surround its prevention during colder months. Understanding these can prevent potentially dangerous lapses in care.Many owners mistakenly believe that mosquitoes, the primary vectors for heartworm, disappear entirely during winter, thus rendering medication unnecessary. This belief can lead to a false sense of security.

• Misconception 1: Mosquitoes do not survive winter. While mosquito populations significantly decrease in colder climates, some species can survive as dormant eggs or even adult mosquitoes in sheltered environments. In warmer regions, mosquitoes can be active year-round.
• Misconception 2: Heartworm larvae die in cold weather. Heartworm larvae, once transmitted to a dog, require a certain period to mature and migrate to the heart. This development is temperature-dependent. While it may slow down in cooler temperatures, it does not necessarily cease entirely, especially in milder winters or if a dog is exposed late in the transmission season.
• Misconception 3: My dog stays indoors, so they are safe. While indoor dogs have reduced exposure, they are not entirely immune. Accidental outdoor excursions, or even mosquitoes finding their way indoors, can still pose a risk.
• Misconception 4: If my dog hasn’t had heartworm before, they don’t need it in winter. Heartworm can affect dogs of any age and previous health status. The risk of infection is present whenever mosquitoes are active, regardless of a dog’s history.

Cost-Effectiveness of Year-Round Prevention Versus Treating Infection

The financial implications of heartworm prevention are often weighed against the cost of treating an established infection. A comparative analysis clearly favors consistent preventative measures.Treating a diagnosed heartworm infection is a complex, lengthy, and expensive undertaking. It involves multiple veterinary visits, diagnostic tests, restrictive exercise protocols, and potentially dangerous medications to kill the adult worms.

The cost of a year’s supply of heartworm preventative medication is a fraction of the expense and risk associated with treating an active heartworm infection.

For example, the cost of annual heartworm testing and a year of preventative medication for a medium-sized dog might range from $150 to $300. In contrast, treating heartworm disease can easily cost upwards of $1,000 to $2,000 or more, not including the potential long-term health complications and reduced quality of life for the dog.

Questions for Your Veterinarian About Winter Heartworm Prevention

Engaging in open communication with your veterinarian is crucial for tailoring a heartworm prevention strategy that best suits your dog’s specific needs and your local environment. Asking informed questions ensures you have a comprehensive understanding of the risks and the recommended course of action.Your veterinarian is the most reliable source of information regarding heartworm prevention in your region. They can provide personalized advice based on disease prevalence, your dog’s lifestyle, and the latest veterinary guidelines.

Questions Often Asked: Do Dogs Need Heartworm Medicine In The Winter

Does heartworm medication taste bad in winter?

Actually, the taste of heartworm medication is generally consistent year-round. While the weather might change, the flavor profile of that little pill (or chewable!) remains remarkably stable. So, don’t expect a minty fresh winter edition or a bland summer blend – it’s pretty much the same delicious (to your dog, perhaps not to you) experience.

Can my dog catch heartworms from another dog in the winter?

Nope! Heartworms are transmitted by mosquitoes, not dog-to-dog cuddles. So, even if your dog is sharing a warm bed with an infected canine friend during a chilly winter snap, they’re safe from direct transmission from their buddy. The mosquito is the only intermediary here.

If I live in a very cold climate, can I skip winter heartworm meds?

While it’s tempting to think a deep freeze equals zero mosquito risk, it’s a bit more complex. Even in cold climates, there can be pockets of survival for mosquitoes, or a sudden warm spell could reignite their activity. Plus, some medications protect against other nasty parasites that are active year-round. It’s always best to chat with your vet about your specific locale and their recommendations.

What happens if my dog misses a winter dose?

Missing a dose, especially during a time when mosquitoes
-could* still be a threat (even a tiny one!), is like leaving the door ajar for trouble. The protective window shrinks, and if an infected mosquito happens to bite, your dog could be at risk. Consistency is key to keeping that heartworm invader at bay!

Are there any natural remedies that work for winter heartworm prevention?

When it comes to heartworm prevention, the scientific consensus and veterinary recommendations strongly favor approved medications. While many natural remedies exist for various pet ailments, there’s no scientifically proven natural alternative that reliably prevents heartworm disease. Stick with what the experts say for this one!
