Heartworm (Dirofilaria immitis) microfilaria in a fresh blood smear from a young dog recently adopted from a neglectful situation. He was also positive on his Idexx SNAP 4dx, which tests blood for an antigen from adult female heartworms. Fortunately he still looked healthy on clinical exam, so with treatment his prognosis is good.
Our clinic follows the American Heartworm Society treatment protocol:
Heartworms are much easier to prevent than treat! Options include monthly tablets/chews or topicals, or an injection that lasts 12 months. If your dog isn’t currently on heartworm prevention, please contact your vet about testing and getting on a prevention plan.
