I would check out the ingredients of the S.D.??? I haven't heard very good things about it. From other dog forums that I go on they say there is to many byproducts in it. I'm no expert??? My sister has show Goldens and I know her and all her friends stay far away from S.D.
I feed my pups Chicken Soup for the Dog Lover Soul-Puppy. I used to feed them Royal Canin but my Forum friends did not recommend it for my Frenchie. I don't know about Boston's but Frenchies can have a lot of allergies. I still have Katie on puppy food even though she just turned a year old. My vet. said she was fine on it as long as she doesn't start to gain weight. (She is a very picky eater and doesn't eat much) I have heard that Boston's can be little piglets, but not my girl? :wink:
