Heartworm Testing
in Haymarket, VA

Heartworm disease is very serious, but with early detection, your pet has a much greater chance of a full recovery. Regular testing is important because there are few, if any, signs of early heartworm infections. The test requires a small blood sample, which allows us to detect the presence of any heartworm proteins or antigens. An antigen test detects heartworm proteins, which are released by adult female heartworms into a dog's bloodstream.

Your adult dog should be tested for heartworms once per year, during their routine wellness visit. If you have a puppy under seven months old, they should begin heartworm prevention treatment and subsequently be tested for heartworms every six months for a year. After a year, they should be tested for heartworms annually. Dogs older than seven months, who have not been on a heartworm prevention treatment, must be tested before starting prevention treatment.

Dogs (and cats) become infected with heartworms when they are bitten by an infected mosquito. Dogs and cats can only get heartworms from infected mosquitoes. There is no spread from dog to dog, dog to cat, or dog to human. If you have any concerns about heartworm disease and your cat, please give us a call for more information.

Yes, as a pet owner, you can prevent your pet from getting heartworms! Preventive medication is extremely effective. During your visit, after your pet has tested negative for heartworms, we will recommend the preventive treatment best for you.
