Heart murmur

I took my puppy to vet at 7 weeks old for her first vaccine. The vet examined her she told me milly had a grade 2 heart murmur.
Lots of people have told me milly may grow out of this in time i have also been told they are on a grade of 1 to 6 . How bad are a grade 2 and will this have any impact on millys life very worried staffy lover.

hmm I don't know about the different grades , but I had a beautiful doggie Kimba, a corgi/samoyd and he had a heart murmur. It never affected him through his life, but I was always careful to make sure he didn't carry too much weight. I had him for over 12 years...

Grade 1/6 and 2/6 murmurs are generally considered to be "mild".
Dogs with Grade 1/6 and 2/6 murmurs are very unlikely to develop any symptoms as a result of their aortic stenosis and should lead perfectly "normal" lives.

Grade 3/6 and 4/6 murmurs are generally considered to be "moderate".
The majority of dogs with Grade 3/6 and 4/6 murmurs are also unlikely to develop any symptoms, but a small number will go on to become symptomatic.

Grade 5/6 and 6/6 murmurs are generally considered to be "severe".
Dogs with Grade 5/6 and 6/6 murmurs are most at risk of developing symptoms

What symptoms should i look out for ? The vet never really went into it only that is was something she noticed in lots of puppies and Milly had a good chance of out growing the problem.

They way she runs around for hours playing with my other dogs you would think she was in 100% health.

Very worring though for me.

thanks

The chances are you will never see any symptoms at all.

If the murmur worsens (they don't usually) then the things to look out for would be tiring quickly, an unexplained cough especially after/during exercise or collapse during exercise (which normally only lasts for a minute or so).
Even if it did worsen, it can usually be controlled by medication. A friend's labrador has a grade 4 heart murmur and with tablets, you'd never know there was anything wrong with him.

We were told Billy had the same thing he is fine now
