That happened with Kai when we brought him home. At first I think it was because he was scared when we brought him home...but later on, I noticed that he wouldn't eat on his own. So I ended up feeding it by hand. I tried giving him some kibbles and bits later on..and he ate it gradually. Try Semi-Moist foods...or even canned foods. Kai is REALLY picky..I'm sure your dog will like the wetter foods. We actually just tried out this food where you add just a bit of hot water and it turns to gravy..he just LOVES IT!
