Switched Hunter to Orijen about 2 weeks ago and he's loving it. No more issues with him eating - he almost always comes to the bowl and eats it all. No more sick stomach since switching either. So far so good --
I also switched my little terrier mix to the same food and he loves it! I can definitely see a difference in his skin already! He used to have a fair bit of dry skin but that's going away.
So thanks to everyone for the advice!
