Digoxin Side Effects in Dogs

Digoxin is a canine medication that treats heart problems like congestive heart failure, heart rhythm disorders, and dilated cardiomyopathy. The medicine reduces the strain on a dog's heart and increases its strength. Like many medications, Digoxin carries possible side effects. The side effects in dogs can range from very mild to very severe.

  1. Allergic Reaction

    • Some dogs experience an allergic reaction to Digoxin. The signs of an allergic reaction include hives on the dog's body, swelling in the face and lips, as well as trouble breathing. If this occurs, it's important to take the dog to a veterinarian immediately.

    Decreased Appetite

    • A mild side effect in dogs is a decreased appetite. A dog that has taken Digoxin may not show interest in food or treats. Make sure the dog continues to drink water.

    Heart Problems

    • Take notice of your dog's heart rate before and after starting Digoxin. If the heart rate becomes much slower or much faster, it is cause for worry. Irregular heartbeats signal a need to see a veterinarian.
