Treatments for the Condition in Dogs
Firstly, your vet will ask about your dog’s symptoms. Secondly, your vet will ask about your dog’s full medical history. This will include any heart-specific problems.
Thirdly, a full physical examination will be carried out. Blood and urine tests will be taken.
