Ben was always hungry. I think i mis understood the vet and was giving him a 1/4 cup 4 x a day
I read the IAMs puppy food bag and it says for 10 pounds and 10 weeks 2 1/2 cups a day. So upped to 1/2 cup 4x a day. He seems much less hungry.
Reading a great book on Border Collies ("Understanding Border Collies") by Barbara Sykes, has a great chapter on nutrition, i learned a lot, it seems % of protein and fat are very important depending on dogs age and amount of activity. Plan to reread this chapter. I was so clueless in this area.
Thanks for your input
