Start to feed him in it now! The earlier you start the quicker he'll get used to it. Mind you, in saying that my boy wasn't introduced to a crate until he was 3 years old. He will go and lie in it if the door is open by preference ;) He just loves his crate, even if it's not his, but my bitches one

;) My bitch, on the other hand, still gives it a wide berth...... Mind you,. I only use one in the car, and then in the house when the bitches are in season, so maybe that's why? She wants to 'play' with my boy and knows that she won't be allowed to :D
