Puppy training? Please help!?

Has he been to the vet for a complete checkup? If he has and is healthy then you are just going to have to ignore him. You need to put him in there like it's no big deal. Don't make a big fuss. Just put him in there and tell her he's a good boy. Do this about 10 minutes before you leave him. Don't tell him goodbye. Just go about your normal routine. Upon returning home or to the room. Don't pay any attention to him for about 3 minutes. Do something whereshe can see you. I come in and get the mail and open it. Then I go over and open up the crate and let him out without making big deal about it. If you make a fuss over them then they will think it's better outside then in.
