Before you confine your dog in their crate, make sure they want to go in. Easy to do if you stuff a chewtoy and put it inside, with the dog stuck outside!
Murphy, male, approx 4 years old, Border Collie
He has gotten awfully good at balancing stuff on his muzzle. Training situation- item to be balanced on muzzle:
food, and 2 dogs on each side waiting for him to drop it.
