Thanks for the insite. He never eats his food with the other dogs, and when the other dogs eat, he is in another room. He is just fine with us, we can stick our hands in his dish when he is eating, and he doesnt mind at all.

Last night we gave the 3 dogs rawhide, and they all went to seperate parts of the house, Cooper finished his and then went on to get a rawhide from one of the other dogs. One dogs, will let him have her rawhide, the other dog will put up a fight for it. BUT when Cooper has his rawhide and another dog simply walks by, he will go after the other dog.

I'm going to check out the website right now that you suggested, KYS, and hopefully we get nip this in the bud asap.
