The crate is GREAT! It isn’t prison or jail, providing you don’t use it that way. The crate is an excellent addition to your home. It provides a safe space for your puppy/dog and everything in there should be positive and fun.
So the biscuits you’ve just bought above, you could grab a small handful of those and scatter them in the crate when you want your dog to go to bed, couldn’t you?
It’s also wise to get dogs used to and enjoy being in a crate. You want to be prepared because at some point they’ll likely have to go in one. Operation at the vets? Dog walker have crates in their van? You just never know.
