Most puppies, even the majority of adult dogs, can be crate-trained with relative ease. Remember that the crate should be just large enough for your dog to stand up, turn around, and lie down comfortably. He doesn’t need to be able to play football in it. If you want to get one large enough for your puppy to grow into, block off the back so he has just enough room, and increase the space as he grows. Cover the floor of the crate with a rug or soft pad to make it comfortable and inviting, and you’re ready to begin training.
Start with the crate door open, and toss some irresistibly yummy treats inside. If he is hesitant to go in after them, toss the treats close enough to the doorway that he can stand outside and just poke his nose in the crate to eat them. If you are training with a clicker or other reward marker, each time he eats a treat, Click! the clicker (or say “Yes!” if you are using a verbal marker).
Gradually toss the treats farther and farther into the crate until he steps inside to get them. Continue to Click! each time he eats a treat. When he enters the crate easily to get the treats, Click! and offer him a treat while he is still inside. If he is willing to stay inside, keep clicking and treating. If he comes out that’s okay too, just toss another treat inside and wait for him to re-enter. Don’t try to force him to stay in the crate.
When he enters the crate to get the treat without hesitation, you can start using a verbal cue such as “Go to bed” as he goes in, so that you will eventually be able to send him into his crate on just a verbal cue. When he happily stays in the crate in anticipation of a Click! and treat, gently swing the door closed. Don’t latch it! Click! and treat, then open the door. Repeat this step, gradually increasing the length of time the door stays closed before you Click! Sometimes you can Click! and reward without opening the door right away.
When your dog will stay in the crate with the door closed for at least 10 seconds without any signs of anxiety, close the door, latch it, and take one step away from the crate. Click!, return to the crate, reward, and open the door. Repeat this step, varying the time and distance you leave the crate.
