Yoga studio vs an interrogation room
When a dog knows how to stay calm in the crate, you don’t need to put lots of kongs stuffed with peanut butter and toys and what not to make the dog like the crate. I train dogs to go into crates without anything fancy inside the crate. They don’t go inside because they think it is a game room or a buffet restaurant; they go inside to relax. It is a matter of perception. You can look at an empty room with a mirror as an interrogation room and freak out and really want to run away, or you can look at it as a yoga studio and even pay money to go inside to relax. The yoga room does not have to be filled with food for you to like it. On the other hand, if you believe you are being interrogated, you can have lots of food placed in front of you and you still can’t wait to get out. It is not about materialistic stuff you have inside, it is about the mental enjoyment of calmness and security that a dog has associated with the crate. When a dog looks at a crate as a yoga studio, he will love to go inside, stay inside, and enjoy being inside - without any bribe.
