I use solid gold puppy food mixed with canned (lamb, barley, brown rice and carrots is the mildest and good for puppies) and Herb is doing really well on it, I also use the seameal supplement. He had a little rash when we first got him and this cleared up as soon as he was totally on solid gold. he also loves it, but he's a little pig and loves everything!
My mom has had our wheaten Poppy on it all her life and shes a very healthy girl
