Uh Oh only 3 1/2 cups. My mom put a crock from a crock pot out one for Buddy and one for Dollie because they would fight over food, so I am sure they are being way over fed. Dollie (Lab) is defintely over weight, but Buddy looks pretty good, but since he will be 3 in April I was wondering if he will fill out any more then he already is.
Bev, it really depends upon the kind of food & the activity level of the dog, so I wouldn't necessarily worry if Buddy's weight seems right. Once you have him at home with you, you may want to take him for a little drive to the vet to step on the scale. This is also a good way to make him more comfortable with vet visits, especially if everyone pets him & he gets lots of treats.
Anyway, if his weight seems in line with other pyrs of his height & gender, and his ribs feel fine to you & the vet, then I wouldn't be concerned. It may be that he's just been eating a food that has a lot more filler in it, so he's needed more of it to be adequately fed. That's one of the many benefits of Innova, it takes less food to feed them and thus they make less poop!
