I got my first Cavalier just over a year ago in March. She is 3 years old now, had pups before I got her. She is a Blenheim and just a lover, so sweet . So what else is new?! Her name is Maggie Mae. She is a little overweight as is her owner. She snores quite a lot! I am worried about her heart as she puffs after a short walk. I must ask my vet to check her heart and see what he thinks. I would appreciate anyone else with more experience than I. Thanks!
