Dogs and cats get heartworm disease when an infected mosquito bites them. The heartworm then gets inside of their body and can reproduce, which only worsens your pet’s symptoms. The illness is much more prevalent in dogs, but cat owners also need to know about the symptoms so they can prevent and treat it if necessary. Puppies can start on preventive heartworm medication at eight weeks old without any type of testing. At six months of age, a puppy needs to test negative for heartworm infection before a veterinarian can prescribe preventive medication.
Heartworm testing in dogs requires only a simple blood test. Testing is a bit more complicated in cats and requires several blood tests before a veterinarian can make a diagnosis. This testing is typically done at the request of the cat owner when he or she suspects the animal may have contracted heartworm disease.
Previously, it was common practice for pet owners to give preventive heartworm medication from early spring to the first frost of winter. However, the American Heartworm Society now recommends keeping up with treatment all year long. This has the added benefit of killing other parasites that may be inside of the animal.
Signs of Heartworm Infection
Cats and dogs show signs of heartworm infection differently. Because of a cat's smaller body size, it's more likely for heartworm to affect their lungs and make it difficult to breathe. In dogs, heartworms live in the ventricles of the heart and the heart itself. The following are common symptoms of heartworm disease, although some pets show no symptoms at all:
- Weight loss
- Fatigue unrelated to exertion
- Loss of appetite
Treatment can be long and painful for an animal infected with heartworm. Fortunately, heartworm disease is almost 100 percent preventable with the proper medication. We encourage you to speak to Dr. Henkes or Dr. Weckwerth at Weckworth Animal Hospital for specific recommendations. He takes your pet’s species, age, weight, lifestyle, and several other factors into consideration before recommending one product over another.
