1) Crate-training is not cruel, inhumane, or even stressful as long as the crate is comfortable, entertaining, and introduced properly.
2) Crates can help with housetraining and setting a dog up for success as he learns house manners by limiting the time he’s unsupervised and could get himself into trouble.
3) A crate offers a dog a safe, secure corner of the world that is solely his. This can help him manage stress or fear in a healthy way – if he gets overwhelmed by household activity (noise, excited children, strangers visiting), he knows he can retreat to his crate and nobody will ever bother him in there.
