A crate, or, in other words, short-term close confinement, can be used to help dogs teach themselves two very important skills. The first is eliminating only when and where it is appropriate. The second skill is keeping out of trouble – behaving appropriately in the house. Without these two skills, a dog doesn’t have much of a chance in this world.
To get your dog to go into the crate, 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).
