Hearing that your dog has a heart murmur can feel overwhelming. Many pet parents worry about whether exercise is safe or if their pup needs to stop being active altogether. The good news is that most dogs with heart murmurs can still enjoy daily walks and play as long as activity is tailored to their condition and monitored closely.
This guide explains what a heart murmur means, how it affects exercise, and how to create safe routines that keep your dog both happy and healthy.
What is a heart murmur in dogs?
A heart murmur is an abnormal sound caused by turbulent blood flow in the heart. Murmurs can range from mild and harmless to more serious, depending on their grade and underlying cause. Some murmurs are “innocent” (especially in puppies) while others are linked to structural heart disease like mitral valve disease or cardiomyopathy.
Your vet will grade the murmur from 1 (very soft) to 6 (very loud) and may recommend additional tests such as an echocardiogram or X-rays to determine how much the heart is affected.
Should dogs with a heart murmur exercise?
Yes, in most cases, but with limits. Exercise is important for maintaining muscle tone, supporting a healthy weight, and preventing anxiety or restlessness. The key is moderation. Too much strenuous activity can place unnecessary stress on the heart, while the right amount of gentle exercise helps overall well-being.
Safe exercise plans for dogs with a heart murmur
1. Keep walks short and steady
Instead of long, strenuous hikes, aim for 10–20 minute slow-paced walks once or twice a day. Choose cooler times of day to avoid heat stress.
2. Avoid overexertion
Skip activities that involve intense running, jumping, or chasing, like fetch marathons or agility courses. Monitor your dog for signs of fatigue, coughing, or difficulty breathing, and stop if these appear.
3. Encourage gentle play
Tug toys, puzzle feeders, or short indoor play sessions provide mental and physical stimulation without overloading the heart.
4. Prioritise consistency
Regular low-impact movement is better than bursts of high-intensity play. Consistency keeps circulation and weight in check.
5. Adjust with age and progression
As heart disease progresses, your vet may advise reducing exercise further. Always follow up with routine check-ups to adjust your dog’s activity plan.
Warning signs to watch for during exercise
- Laboured or rapid breathing
- Persistent coughing
- Blue-tinged gums or tongue
- Sudden weakness or collapse
- Unusual lethargy
Supporting heart health through nutrition
Diet plays a role in managing heart conditions. Look for dog foods with moderate sodium levels, added taurine, and omega-3 fatty acids to support cardiovascular function. Supplements like the Doctor Paws Super Chew can provide omega-3s that help reduce inflammation and support circulation, complementing a heart-healthy lifestyle.
Takeaway
A heart murmur doesn’t mean your dog has to live a sedentary life. Safe, gentle, and consistent exercise is not only possible but beneficial. The best plan balances activity with rest, keeps your pup at a healthy weight, and is always guided by your vet’s advice.
Combined with regular check-ups, the right nutrition, and supportive supplements like Doctor Paws Super Chew, you can give your dog a happier and healthier life, even with a heart murmur.
