My 7 month old Boxer puppy was recently diagnosed with a grade 2 heart murmur. Although lately I've started to see other symptoms. He will run and play for about 30 seconds to a minute and have to stop to catch his breath. He hangs his head low and breathes heavy usually for about a minute but during that time he cannot move. I am very concerned considering how young he is. Any suggestions or help is greatly appreciated. I have a vet visit scheduled this upcoming week to see if there has been any change in his murmur.
I've got a 6 month old puppy same but mine's bad so I've had go find a cardiologist and he has to have a scan tomorrow. Vets couldn't do no more so that's what they advised.
