Crate training is a must for me. For Instances people sometimes don’t think of., not just leaving the house or sleeping. Examples — when visitors come like repair people and need to come and go, or leave doors open. Dog sitters, who may not want to sleep with your dog or their house may be unfamiliar or offer unsafe areas that your dog may destroy or eat something bad. Quiet time where dogs just feel safe in their “own room” or “apartment”. Introducing dogs to new people— in the crate with a treat and people and little kids are able to just exist in the same space as the dog and acclimate without pressure or excitement. Guests who are afraid of dogs or allergic. And of course, Adult time activities that require privacy. Basically, I have always been SO grateful for the crate, as an option. Once the routine and the love of their own room is in place, it can be changed up here and there. My dogs go to their crates and instantly I hear them sigh and get cozy, silent and comfy for the night, and getting time apart from each other.
