You should get your dog seen by our veterinarian right away. Rapid heartbeat in dogs could indicate that he is in pain, has heat disease, an electrolyte imbalance or another hidden condition. Left untreated it can lead to injury of the heart itself and/or congestive heart failure. Your vet will do an exam, blood work and x-rays to determine the cause of the illness and suggest an effective treatment plan.
