Oh boy.....the food issue lol. I use Evo for Noah & Diesel, Barf for Bella, Innova for Grandpa and CB and a variety of California Natural etc for the rescues.
Every time I have dogs return from Wellington Park where they are fed Eagle Pack, their coat and skin looks sensational!
What you need to look for is the ingredients on the back of the pack. You DON'T want to see corn meal or brewers rice as they are cheap unhealthy fillers.
I use a LOT of minced chicken carcess to mix through the dry food and I go through tons of chicken necks for sparkly healthy teeth.
