Since we are fortunate to have on the Forum someone who is both a vet and a Sheltie owner, I've asked Dr. Mac (The Quahog) if he'd share his opinion with us on high protein dog foods. It seems to be one of several topics we've discussed here at great length, and I thought it would be helpful to hear from someone who is really an expert. I think many of us who have questions about this can benefit from his viewpoint. Discussion is welcome; please remember he's doing us a favor to jump into the fray, so even though this is a topic many are passionate about, let's try to keep an open mind, stay on topic and be respectful. Tossing to you, Dr. Mac!
