Heart valve narrowing (mitral and tricuspid) in dogs affects blood flow. The condition causes high blood pressure and makes exercise hard.
Unfortunately, certain dog breeds including Labrador Retrievers and Old English Sheepdogs suffer from the condition more than others.
Technically, the condition is also called atrioventricular valvular stenosis.
If you see the signs of the condition in your dog, then get to a veterinarian for a proper diagnosis and treatment.
Here’s what you should know about the symptoms, causes, and treatments for the condition.

Causes of Heart Valve Narrowing (Mitral and Tricuspid) in Dogs
The cause of the condition is often congenital. This means that a dog is born with it. However, some of the other factors that might cause the condition include:

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 complete medical history. This will include any breed-specific problems.
Thirdly, a full physical examination will be carried out. Blood and urine tests will be taken. Additionally, X-rays and an electrocardiogram (EKG) can monitor your dog’s heart function.
Ultimately, heart medicine is used to treat the condition. As always, if your vet prescribes your dog any medicine, make sure to stick to the correct dose and frequency instructions. Also, complete the full course of medicine.
While recovering at home, it is important to provide your dog with a quiet and calm environment. Also, keep up regular visits with your vet to monitor your dog’s heart function.
