We've fed him gravy train before and he ate that great, the last time we bought it he wouldn't eat any of it. So we tried Alpo Bits and Bones or something like that, he takes a few bites.So I tried adding some canned food to his dry, nope, he didn't like that either.
He is kept in a large pen by himself because right now the puppies are too young to leave outside so the momma dogs have to be out with them so he has been alone for a while. When I am outside for any length of time I let him out to run and play but he can't stay loose.
Due to some issues with ex neighbors he now thinks all strangers are going to be mean to him so he gets defensive and has to be kept in the pen or on a run. He has 2 large dog houses to go in when he wants to but I think he gets lonely and I'm sure he gets tired of being cooped up while all the other dogs are free to run around the farm. He's lost some weight and we've switched his feed atleast 4 times since all this started. The other dogs aren't really picky.
I've decreased how much he gets fed by half because it's pointless to offer him a lot that just gets spoiled.
