DIROBAN - Heartworm symptoms, signs and stages

Heartworm disease symptoms in dogs

It’s hard to spot early signs of heartworm disease. That’s why it’s so important for your dog to be tested every single year. In the more advanced stages of the disease, symptoms include fatigue, labored breathing and coughing.²

If you see any of the following signs² in your dog, contact your veterinarian immediately.

SIGNS OF HEARTWORM DISEASE IN DOGS

Fatigue when exercising

Occasional coughing

Loss of weight and/or appetite

Persistent fatigue, excessive coughing and shortness of breath (severe cases)

Confirming the diagnosis

If your dog’s blood work has tested positive for heartworms, your veterinarian will confirm the diagnosis with follow-up tests. Heartworm disease treatment can be complex and challenging for both you and your dog, so your veterinarian will want to confirm the right DIROBAN treatment plan.
