Preventing Heartworm Disease in Dogs and Cats

Preventing Heartworm Disease in Dogs and Cats

Heartworm disease is a serious condition that can result in heart failure, severe lung disease, and damage to other organs. When left untreated it most often leads directly to death in infected hosts. Most commonly found in dogs, but also posing a risk to cats, our Stuart vets talk shop on heartworm disease in today's post.

Firstly, what is heartworm disease?

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

Pets including dogs, cats, and ferrets may become definitive hosts, meaning that worms live inside the animal, then mature into adults, mate, and produce offspring. This serious condition is called heartworm disease because the worms live in the heart, lungs, and blood vessels of an infected pet. 

It sounds scary, what are the symptoms of heartworm disease?

Symptoms of heartworm disease typically don't appear until the disease is advanced. The most common symptoms of heartworm disease include swollen abdomen, coughing, fatigue, weight loss and difficulty breathing. 

Well then, 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.

Not detectable for five months?! What do I do 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.

I see, then 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.
