Border Collie Mix Eats Beneful Healthy Weight

I have a Border Collie mix dog (not sure what the other part is). His name is Bear and he is about 3 years old. He eats Beneful Healthy Weight. When he was a puppy he ate Purina Puppy Chow. We purchased this dog food primarily because of the price/quality. It was low priced and seemed to have all the vitamins and nutrients we desired. It was not recommended by a vet, he didn't recommend any particular brand.

We purchase this food at Sam's Club because it is the best price. Occasionally, for a treat for him, we mix in some wet dog food (canned) with the dry dog food. I know I get tired of the same old same old. When we mix it in he is happy as a clam.
