For certain diseases, prevention is the key to keeping pets healthy. For heartworm disease, this stands true. But, what is heartworm disease? And, what is the safest heartworm prevention for dogs?
In this article, we'll cover:
- The reality of heartworm disease

- Types of heartworm medicines for dogs
The reality of heartworm disease
Heartworm infection is a life-threatening illness spread by mosquitoes. When an infected mosquito bites your dog, they spread heartworm larvae to your dog's bloodstream.
The larvae eventually grow in size and travel to your dog's heart and pulmonary artery. If left untreated, these parasites can grow up to a foot long.
- Pale gums
- Weight loss
- Labored breathing
- Sensitive stomach
- Kidney failure
All it takes is one mosquito bite to put your pet's health at risk. That's why annual testing for heartworms and preventive medications are important in your dog's life.
Dogs diagnosed with heartworm infection are not eligible for prevention medications. Instead, a vet will recommend heartworm treatment to treat your dog's condition.
It's important for pet owners to stick to a monthly prevention plan. Staying consistent with prevention is the best way to keep your dog free of heartworm infection.
What is heartworm prevention
Heartworm prevention medication works retroactively to treat the development of heartworm infections. This means it works to prevent the growth of heartworm larvae in your dog's body.
Using heartworm preventatives is the best way to prevent heartworm disease in dogs. And, the best prevention products can also protect your pet from other internal parasites like hookworms and roundworms.
Heartworm medication comes in different forms:
- Chewable tablets
- Soft chews
- Topical treatments
Topical treatments are applied monthly and are split into weight breaks. Injections are given by a veterinarian every 6 or 12 months.
If your pet uses a chewable tablet or other oral medication for heartworm, it typically comes in three weight breaks for smal;, medium, and large dogs. For extra large dogs, you may need to combine doses of heartworm preventives to cover your dog's weight.
Pet parents cannot buy pet meds for heartworm without a prescription from their veterinarian. To get a vet prescription, your dog will need a heartworm test.
The American Heartworm Society recommends taking your dog to a veterinarian for a heartworm test every 12 months. And, dogs should receive heartworm preventatives 12 months a year.
What to look for in heartworm prevention medication
When choosing prevention medication for your dog, there are important factors you should look for. The best heartworm prevention pet meds have the following 5 qualities.
1. Prevent heartworm larvae growth.#
The best heartworm prevention medication prevents heartworms from developing out of the larvae stage. These parasitic worms are harmless to your dog, as long as they do not develop into adult heartworms.
2. Cover hookworms and roundworms.#
Consider choosing a heartworm medication that also treats internal parasites in your dog's body like hookworms and roundworms. These parasites can damage your dog's health and require more trips to the vet for treatment.
3. Made with safe and effective ingredients.#
The active ingredients in the heartworm medicine you choose should be vet-quality and FDA-approved.
The most common active ingredient in heartworm pet meds is ivermectin, but other prevention medications use ingredients such as:
- Milbemycin oxime
4. Do not cause adverse reactions.
Most dogs should not have any allergic reactions or side effects to their heartworm medication. If your dog has an adverse reaction after taking heartworm drugs, visit your vet immediately for a dog check-up.
Some herding dog breeds and mixed breed dogs have a genetic mutilation called MDR1. The MDR1 gene causes sensitivity to ivermectin.
Some common breeds that are prone to the MDR1 gene include:
- Australian Shepherd
- Border Collie
- German Shepherd
- Old English Sheepdog
- Shetland Sheepdog
- Miniature American Shepherd
- Skye Terrier
- Mixed breeds that may have herding-breed heritage
No matter what breed of dog you have, talk to your veterinarian about the best option for heartworm prevention.
5. Delivered every month.
Most heartworm preventatives come in packs of three or six. That means pet parents have to remember to give their dogs their treatment every month.
Look for a product that does the work for you by delivering your pet’s dose every month right when they need it.
