Crate Training

Training a puppy to be comfortable in a crate is a popular way to
provide safe confinement during housetraining. The majority of puppies
will rapidly accept crate confinement when you make the introduction
fun. Since it is important to associate favorable things with the area
where your puppy is confined, it is a good idea to play with him there,
or simply spend some time reading or watching television nearby as he
relaxes with a favorite chew toy. If he is only in the area when you
leave, it becomes a social isolation area that he eventually may resist
entering.
A good time to start crate training is at dinner time. Feed your puppy
his dinner, one piece at a time, by tossing pieces of kibble into the
crate for him to chase and eat. This way, you can make a game out of
training.
When you pick up his toys, store them in the crate so he will enter on
his own to play. You may even want to occasionally hide a biscuit in
the crate as a nice surprise.
You should not use the crate for periods that exceed the length of time
the pet can actually control the urge to urinate or defecate. If you
are gone for long periods each day, you will need to provide a larger
confinement area. You may want to consider using an exercise pen or
small room.
Provide an area large enough so that if your puppy has to eliminate
when you are gone, he can do it in a space that is separate from his
sleeping area. A 15- to 30-square foot area is adequate for most
puppies. If he chooses a specific place to eliminate, cover it with
paper to make clean up easier.
