Thanks for the responses, I've got to change food again because I don't feel that Kane is getting enough of what he needs. He was a rescue dog and very thin when I got him. He had previously been fed a cheap grocery store brand and I switched him to nutro Natural Choice, but I'm just not seeing the results I was hoping for. I assume it takes some time to undue the damage done by neglect and poor food in the past, and perhaps there is nothing wrong with the Nutro, but he sheds constantly, his nails are brittle (infact that shatter when he gets out and runs hard) so I'm just looking for the best food that will set well with him. Sounds like Canidae is very good, but Wysong really worked wonders -- again that was years ago. It's hard know what to look for in good dog food or rather what to avoid. Thanks again.
