Heart Health in the Boston Terrier

Quick answer

Boston Terriers are known for their lively and affectionate nature, but they do have specific health considerations regarding their heart. The primary concern is a condition called Myxomatous Mitral Valve Disease. While this is a recognised tendency in the breed, proactive monitoring of your dog's breathing, gum color, and general activity levels can help you detect changes early. Regular check-ups with your veterinarian allow for timely diagnostic testing, which is the most effective way to manage heart health.

Understanding Myxomatous Mitral Valve Disease

Myxomatous Mitral Valve Disease is a condition where the valve responsible for keeping blood moving in the right direction through the heart begins to change. This is a recognised tendency in the breed. When the valve does not close as tightly as it should, blood can leak backward, forcing the heart to work harder to circulate oxygenated blood throughout the body.

At home, you might notice your dog tiring more easily during exercise, or you may observe a subtle change in their breathing pattern while they are sleeping. The veterinarian will typically begin an assessment by listening to your dog's heart with a stethoscope. If they hear a heart murmur, this is often the first indicator that further investigation is needed. To confirm the diagnosis and assess the severity of the valve changes, your vet will likely recommend an echocardiogram. This ultrasound of the heart allows the clinician to see the structure of the valves and measure how well the heart is pumping. Because this condition is a recognised tendency, your vet may suggest periodic screening even before you notice any symptoms.

Monitoring Breathing at Rest

One of the most valuable tools you have as an owner is observing your dog's breathing while they are completely relaxed or asleep. A healthy dog should breathe quietly and evenly. If you notice your dog panting when they are not hot or exercising, or if their breathing seems labored or rapid while they are resting, this is a signal to contact your clinic. You can count the number of breaths your dog takes in one minute while they are sleeping to establish a personal baseline for your pet.

The Importance of Gum Color

Your dog's gums are a window into their circulatory health. Healthy gums should be a vibrant, bubblegum pink. If you notice the gums appear pale, white, or have a bluish tint, this indicates that the tissues are not receiving enough oxygenated blood. You should check your dog's gum color regularly as part of your routine care. If the gums are anything other than a healthy pink, this warrants a prompt assessment by your veterinarian to determine if the heart or lungs are struggling to maintain proper circulation.

Mobility and Behavior Baselines

Heart conditions often manifest as a gradual decline in energy or a reluctance to engage in normal activities. You know your dog's personality better than anyone. If your dog suddenly stops wanting to go for their usual walk, struggles to climb stairs, or seems lethargic throughout the day, these changes in mobility and behavior should be documented. While these symptoms can be associated with many issues, they are important indicators that your dog's heart may not be keeping up with their physical demands.

Body Condition Score

Maintaining an ideal weight is vital for heart health. Excess weight puts additional strain on the cardiovascular system, making it harder for a heart that is already dealing with valve disease to function efficiently. Your veterinarian can help you determine your dog's body condition score. This is a scale used to assess whether your dog is at a healthy weight, underweight, or overweight. Keeping your dog at their ideal weight is one of the most effective ways to support their heart function throughout their life.
