dog feels comfortable going inside and outside the crate, try closing the door of the gate while he eats his meal. leave the door closed for a few minutes after he finishes eating. for the first few times, he might whine. do not let him out of the crate until he has stopped whining.
the dog should now feel comfortable being in the crate for small amounts of time without crying to be let out. start leaving him in the crate for 10 minutes to 30 minutes at a time. encourage the dog to enter the crate by giving him a treat. while he is confined, walk around to different rooms
