Heart disease in dogs does not occur as often as it does in humans, but it can happen due to genetic predisposition or old age. Some larger breeds like Great Danes, Irish Wolfhounds, and Boxers are susceptible, as well as smaller ones like Dachshunds, Boston Terriers, and Pomeranians. All of these symptoms below could be signs of other conditions, but these are generally the signs that point together toward canine heart disease.
If your dog ever faints, you should take it to the vet at once. Fainting could be a sign of several life-threatening conditions, including heart disease. Fainting happens when the brain fails to get enough oxygen, which for dogs could mean disturbed heart rhythm.
Coughing that goes on for more than three days is a serious symptom. A canine may cough for a wide range of reasons, but it could mean that heart inflammation is compressing the lungs or that there is a backup of fluid.
A dog may also pant more or have difficulty breathing if it has heart disease. The condition may lessen oxygen in the blood, so the lungs are working harder to get the needed oxygen. This is especially true when compiled with other telling symptoms.
With how hard a pet may have to work trying to receive enough oxygen in the bloodstream, a dog may grow tired and become lethargic. If your dog is constantly worn out, coughing, panting, etc., something may be severely wrong.
Loss of Appetite
Another sign of heart disease is a loss of appetite and consequential weight loss. Sudden changes in weight are not to be taken lightly. However, a pet may also have sudden weight gain due to abdominal swelling.
Changes in Behavior
Changes in usual behavior typically signal that something is off. When dogs are sick, they may lose their appetite, lose interest in activities they enjoy, and self-isolate. Other signs include a feeling of discomfort or restlessness.
A vet can conduct various tests to diagnose the problem and treat it with medicine accordingly. If necessary, the vet can perform surgery. If you suspect your pet has heart disease, Everhart Veterinary Medicine in Baltimore can help!
