Golden retriever puppy has heart gallop sounds. Will she outgrow it?

Thank you for submitting your question regarding your potential new puppy. Young puppies can occasionally have what is known as an innocent murmur. This is a heart murmur they will outgrow usually by 6 months of age and is not associated with any ongoing disease. Other murmurs are associated with congenital heart disease and go on to cause the puppy significant disease. I recommend having the puppy evaluated by a board certified veterinary cardiologist. A procedure known as an echocardiogram will likely be needed to assess for any structural heart disease. This will give you the longterm prognosis for the puppy. I hope this information helps!

Thank you for submitting your question regarding Finely. The murmur is concerning and should not have been affected by him have been painful. I recommend having him evaluated by a veterinary cardiologist. He should have an echocardiogram prior to you agreeing to purchase him. Some murmurs can be innocent in puppies, meaning that they will eventually grow it. However, most are associated with congenital heart defects. You will want this information prior to buying the puppy so that you can plan for ongoing medical expenses that he may have. I hope this information helps.

This is common and generally they do grow out of it. Norwich Terriers are not at high risk for heat disease. I don't know of any statistics on this. If the murmur persists a grade 1/6 is very mild and would not require treatment. Generally a grade 3 or higher may need medication to improve the heart function and reduce fluid in the lungs. Most dogs with heart murmurs live long lives with minimal issues. Personally I would adopt the puppy anyway as I would not expect it to progress or effect the dogs quality of life. To be safe you may want another veterinarian to examine the pup and listen also. It's always a good idea to get a second opinion.

Most puppies with grade 1 heart murmurs have these due to physiologic changes that they grow out of. However, there are some heart conditions that can start as a grade 1 murmur which can progressively worsen over time. Odds are in your favor that Nelson would grow out of this murmur and that it is insignificant. There is always that off chance that he has a more severe condition. Consider asking the breeder to include progression of heart disease (indicated by a worsening murmur) in the contract, in that if it does progress, you could return Nelson (unless you believe that you will get too attached). This is not an easy decision without a definitive right or wrong answer.

At this age, as long as Kona is doing well, I would just monitor for now. Continue going in every 3 weeks for her vaccinations and the veterinarian will check the murmur with each visit. Innocent murmurs, which happen often, are harmless heart murmurs that typically show up around 6-8 weeks of age and can persist for several months. The murmur will typically resolve by 4-6 months of age. If the murmur is still there at the time it is recommended to spay, I would hold off on the spay procedure and have a cardiologist do an echocardiography on her to see what the cause of the murmur is. I would avoid making her exercise too hard but she can still play. I hope this helps guide you in the right direction!

Most dogs with a heart murmurs are fine and symptom free, there is no way to know for sure but when she is a little older you can ask your vet to refer you to a cardiology specialist to have a few tests done to check if her heart is in healthy condition.

Unfortunately this is a typical sign for a heart defect present from birth called a patent ductus arteriosus or PDA. Provided that the condition is treated before heart failure develops, the success rate associated with surgical closure is very high and the prognosis for a normal life after surgery is excellent. Sometimes, the dog may require heart medication in the future if irreversible heart damage was present before surgery.
