Hi all, help needed please, recent visit to the vet, we were told Max has a heart murmer. recently on his walks he has to stop then only continues very slowly. Today he stopped completley when I pulled him (gently) he fell over, he got up but continued on his walk very slowly, Max is coming up 8 this year, is it age or something I need to get checked, also, before slowing down he tends to heave and gag a little.?
thanks
thanks
