I just adopted a two year Pit Bull who is very loving and affectionate. We bought a crate for him and left for twenty minutes the first day, he screamed the whole time, day 2, we left him in the crate for two hours, we came home and he broke out tipped over garbage and scratched at door, what do we do?
Your dog is having anxiety issues. There should be good posts on this website or on the internet. He wont grow out of it so the sooner you get started working on it the better. Good luck.
Try giving him a KONG filled treat toy or a huge bone when he goes in. Use an irresistible treat for him that he only gets when he's in the crate. This worked when I rescued an 8 year old non-housetrained husky. He learned to love his crate.
