I have had Chico for about 2 months now, he was fine at first, but now whenever he goes in his crate he has a mental breakdown, it is getting worse and worse every day. I have no clue what to do. I have tried leaving him in there for a few minutes at a time and coming back, putting a heating pad in there, putting a shirt of mine in there, giving him treats when he is in there, feeding him in there. Nothing works. He won't touch treats when he is in there, not even his Kong stuffed with treats and sealed with peanut butter. I've tried feeding him dry food mixed with canned, which he never gets otherwise, he always eats only dry, he won't touch it. He howls, barks, whines, and just goes crazy. I ignore him, he will keep at it all night. I can't get another dog, he already Harley (the rottweiler mix) so its not like he is completely alone. Any one have any other suggestions that they have tried. I feel so bad for him listening to him whine, but I know I have to ignore him. He won't even go outside by himself without whining.
I have 1 Chi, 1 Rottweiler/lab mix, 2 cats, a blind leopard Gecko, and a saltwater fish tank
