My puppy has a heart murmur. Is being lazy and unmotivated normal?

Updated On September 23rd, 2025

Pet's info: Dog | Weimaraner | Male | unneutered | 20 lbs

Hello, i just recently got a 14 week old silver weimaraner. Pure bred from a reputable certified breeder. He informed me that I shouldn't be worried that my pup has a small heart murmur. I've noticed compared to other pups I've owned in the past he doesnt bark much. Hes pretty lazy and doesnt scarf down food like other pups ive owned. It's making it semi hard to train him to come. Because hes reluctant to care about any treats. He still eats then just isnt motivated. Is this normal?willthischang

Unfortunately you cannot know if this murmur is permanent or if this is an 'innocent' murmur. Here is an excellent link: vcahospitals.com/know-your-pet/heart-murmurs-in-dogs If the murmur does not go away on it's own by 5-6 months of age, it's likely not an innocent murmur and in that scenario, it would require a cardiac work up to determine the cause of the murmur and any continuing implications. At this point too, it's hard to know if this is just Colt's personality or if this is related to the murmur. I recommend to have him checked by the veterinarian to get a better idea of what is happening and to document the murmur so you can keep tabs on it. I hope this helps and please feel free to post any additional questions.
