hey! my dog is a almost 2 year old Cavalier King Charles Spaniel. he is very big boned, not your typical cavvy. he weighs 26 pounds and the average cav. weight is 18 -20 pounds... is he too heavy? he eats about 1 1/4 cup everyday of Nutro Natural Choice Ultra and gets two 10-15 walks a day. any more advice? should the vet check him out? is he even overweight? thanks for all your help. is there anyone else here who has cavaliers? ps - how do i post pictures here? so i can show you guys a picture of him so you get a better idea of what i'm talking about.
