Hmmm don't know about this one but my dog is 4 yr old and if I give him dried food, he picks out the bits he likes the best and dumps the rest! He isn't kennelled, he lives in the house but he is very "picky" on his food sometimes (not all the time). I have found bits of bonio etc all over the place where he has obviously tried to bury it. I think its just a dog thing? Doesn't worry me overly. I'm sure someone will come along with more suggestions!
