Hi-If I leave my puppy in his crate overnight and when I go out he is fine and doesn't bark or cry-not even on the first night I brought him home. However, he gets really upset if he is out of the crate and I have to leave him in the room (which I only do if I really have to.) If I put him in the crate and he can see me he does the same. He used to nip and I only put him in the kitchen twice for a minute for him to stop. He follows me everywhere and will take his food out of his bowl, eat it sitting next to me before going back for some more. At puppy training when I let him off the lead to play he sits by my side. The trainer got me to walk up and down to encourage him to play and he followed me. I don't mind if it is affection, but don't want it to happen if it is unhealthy for him. He is 15 weeks. Thanks.
