Heartgard is a popular and effective medication used to prevent heartworm disease in dogs. Heartworm disease is a serious and potentially fatal condition that can affect dogs of all ages and breeds. It is caused by the transmission of heartworm larvae through mosquito bites. Once infected, heartworms can grow and multiply in the dog’s heart, lungs, and blood vessels, leading to severe health problems and even death if left untreated.

What is Heartgard and how does it work?
Heartgard is a monthly chewable tablet that contains the active ingredient ivermectin. Ivermectin belongs to a class of drugs called macrocyclic lactones, which are highly effective in preventing heartworm disease in dogs. When administered orally, ivermectin is absorbed into the dog’s bloodstream and distributed throughout the body.
Ivermectin works by targeting the immature stages of heartworm larvae that are transmitted through mosquito bites. It kills these larvae before they have a chance to develop into adult worms that can cause serious damage to the dog’s cardiovascular system. By preventing the development of adult heartworms, Heartgard effectively protects dogs from heartworm disease.
Why is heartworm prevention important for dogs?
Heartworm disease can have devastating consequences for dogs. Once infected, heartworms can cause damage to the dog’s heart, lungs, and blood vessels, leading to symptoms such as coughing, difficulty breathing, fatigue, weight loss, and even heart failure. In severe cases, heartworm disease can be fatal.
Prevention is key in avoiding heartworm disease in dogs. It is much easier and less expensive to prevent the disease than to treat it once a dog is infected. Treatment for heartworm disease can be lengthy, costly, and potentially risky for the dog. By administering Heartgard regularly, dog owners can protect their pets from the dangers of heartworm disease and ensure their overall health and well-being.
How frequently should Heartgard be given to dogs?
| Weight of Dog | Heartgard Dosage | Frequency of Administration |
|---|---|---|
| Up to 25 lbs | 68 mcg | Once a month |
| 26-50 lbs | 136 mcg | Once a month |
| 51-100 lbs | 272 mcg | Once a month |
| Over 100 lbs | Administer the appropriate combination of tablets | Once a month |
Heartgard should be administered to dogs once a month, year-round. It is important to maintain a consistent dosing schedule to ensure the effectiveness of the medication. Skipping doses or administering Heartgard irregularly can leave dogs vulnerable to heartworm infection.
The monthly dosing schedule is designed to provide continuous protection against heartworm disease. Even during the colder months when mosquitoes are less active, it is still important to administer Heartgard as prescribed. Mosquitoes can survive in indoor environments and transmit heartworm larvae to dogs year-round.
What are the potential side effects of Heartgard?
While Heartgard is generally safe and well-tolerated by dogs, there are potential side effects that dog owners should be aware of. The most common side effects include vomiting, diarrhea, and loss of appetite. These side effects are usually mild and transient.
In rare cases, dogs may experience more serious reactions to Heartgard. These can include allergic reactions such as facial swelling, hives, difficulty breathing, or collapse. If any of these symptoms occur after administering Heartgard, it is important to seek veterinary attention immediately.
It is also worth noting that certain breeds of dogs may be more sensitive to ivermectin, the active ingredient in Heartgard. These breeds include Collies, Shetland Sheepdogs, Australian Shepherds, and Old English Sheepdogs, among others. If you have a dog of one of these breeds, it is important to consult with your veterinarian before administering Heartgard.
Can Heartgard be used for puppies and senior dogs?
Heartgard is safe for use in puppies as young as 6 weeks old. It is an important part of their overall preventive care regimen. Puppies are particularly vulnerable to heartworm infection, as they have not yet developed a strong immune system to fight off the disease.
For senior dogs, Heartgard can also be used safely. However, it is important to consult with a veterinarian to ensure that there are no underlying health conditions or medications that may interact with Heartgard. Senior dogs may require additional monitoring and adjustments to their dosing schedule based on their individual needs.
How does Heartgard compare to other heartworm prevention medications?
There are several other heartworm prevention medications available on the market, each with its own advantages and disadvantages. Some common alternatives to Heartgard include Sentinel, Interceptor, and Revolution.
Heartgard is known for its palatability, making it easy to administer to dogs. It is also highly effective in preventing heartworm disease when used as directed. However, it only protects against heartworms and does not provide protection against other parasites such as fleas or ticks.
Other medications like Sentinel and Interceptor offer additional protection against fleas and certain intestinal parasites in addition to heartworms. Revolution provides protection against fleas, ticks, heartworms, ear mites, and certain intestinal parasites. The choice of medication will depend on the specific needs of the dog and the recommendations of the veterinarian.
Is a prescription required for Heartgard?
Yes, a prescription is required to purchase Heartgard. This is because Heartgard contains a medication, ivermectin, that is regulated by the FDA. It is important to consult with a veterinarian before administering Heartgard to a dog to ensure that it is safe and appropriate for the individual dog’s needs.
A veterinarian will consider factors such as the dog’s age, breed, health status, and any other medications the dog may be taking before prescribing Heartgard. They will also provide guidance on the appropriate dosing schedule and any potential interactions or side effects to watch out for.
What should I do if my dog misses a dose of Heartgard?
If a dog misses a dose of Heartgard, it is important to administer the missed dose as soon as possible. However, if it is close to the time for the next scheduled dose, it is best to skip the missed dose and resume the regular dosing schedule.
It is important not to double up on doses or give more than the recommended amount of Heartgard at one time. This can increase the risk of side effects and may not provide any additional protection against heartworm disease.
If you are unsure about what to do if your dog misses a dose of Heartgard, it is best to consult with a veterinarian for guidance. They can provide specific recommendations based on your dog’s individual circumstances.
Can Heartgard be used in conjunction with other medications?
Heartgard is generally safe to use in conjunction with other medications. However, it is important to consult with a veterinarian before administering Heartgard if your dog is taking any other medications.
Certain medications may interact with ivermectin, the active ingredient in Heartgard, and can increase the risk of side effects. Additionally, some medications may affect the effectiveness of Heartgard in preventing heartworm disease.
It is important to provide your veterinarian with a complete list of all medications your dog is taking, including over-the-counter supplements or herbal remedies. This will allow them to make an informed decision about whether Heartgard is safe and appropriate for your dog.
Where can I purchase Heartgard for my dog?
Heartgard can be purchased from a variety of sources, including veterinary clinics, online retailers, and pet supply stores. It is important to purchase Heartgard from a reputable source to ensure that you are getting a genuine product.
When purchasing Heartgard online, it is important to verify that the retailer is authorized to sell the medication. Look for websites that are accredited by the Veterinary-Verified Internet Pharmacy Practice Sites (Vet-VIPPS) program or that display the Verified Internet Pharmacy Practice Sites (VIPPS) seal.
It is also worth noting that some veterinarians may offer discounts or promotions on Heartgard, so it may be worth checking with your veterinarian before purchasing from other sources.
