Preventing Heartworm Disease in Pets

Heartworm disease is a very dangerous condition which can result heart failure, organ damage and lung disease. This condition is generally found in ferrets, cats and dogs. Here, we explain why prevention is key.

What is heartworm disease?

Heartworm disease is spread through mosquito bites and is primarily caused by a parasitic worm called dirofilaria immitis. 

Pets, including ferrets, cats and dogs, may become what is called a definitive host. This means that the worms live within your pet, mature into adults, mate, and then produce offspring to continue the lifecycle.  This condition is called heartworm because the worms live in your pet's heart, blood vessels and lungs.

What are the symptoms of heartworm disease?

Heartworm's symptoms generally don't appear until this disease is in its advanced stages. The most common symptoms include a swollen abdomen, coughing, fatigue, weight loss and difficulty breathing.

How does my vet check my pet for heartworms?

Your vet can complete blood tests to detect heartworm proteins (antigens), which are released into the animal's bloodstream. Heartworm proteins can't be detected until about five months (at the earliest) after an animal is bitten by an infected mosquito.

What if my pet is diagnosed with heartworms?

Keep in mind that treatment for heartworm disease may cause serious complications and be potentially toxic to your pet's body. Not only that, but treatment is also expensive because it requires multiple visits to the veterinarian, bloodwork, hospitalization, x-rays and a series of injections. This is why we say prevention is the absolute best treatment for heartworm disease. 

That said, if your pet is diagnosed with heartworms, your vet will have treatment options available. FDA-approved melarsomine dihydrochloride is a drug that contains arsenic. It kills adult heartworms. Melarsomine dihydrochloride will be administered via injection into your pet's back muscles in order to treat the disease.

Topical FDA-approved solutions are also available. These can help to get rid of parasites in the bloodstream when applied directly to the animal's skin.

How can I prevent my pet from getting heartworm disease?

It's important to keep your pet on preventive medication to prevent heartworm disease. Even if they are already on preventive heartworm medication, we recommend that dogs be tested for heartworms annually. 

Heartworm prevention is safer, easier and much more affordable than treating the progressed disease. A number of heartworm preventive medications can also help protect against other parasites such as hookworms, whipworms and roundworms.
