Whippy can be trusted, she's never really chewed anything or displayed any kind of anti social doggy behavior, to be honest I am not wholly convinced she is actually a dog. She may be an oddly shaped cat. That would make sense
She's only crated because she likes it.
Devil Dog was crate trained because we had a few problems with him including toilet training, cat chasing, snapping and general aggressive behavior. The crate was a place where he could be left when we had small children around who did not know how to properly behave around him and where he would not toilet or attempt to make supper of the cat. He is mainly cured of most issues now and a perfectly friendly, if a little excitable wee terrier, although we have newbie dog who arrived yesterday, so he is currently doing his best impression of the world's most over sexed bi-sexual dog
- we are trying to train the dry humping out of him, it is his last remaining anti-social habit.
He didn't take to his crate as well as whippy. He went in it on command happily enough and stayed in quietly as long as we needed him to, however once we got to a point where we were able to leave the door open he opted to sleep outside of his crate so we folded it up and put it away.
We still get it out from time to time to play crate games with it, so he remains comfortable with it because he is the dog we have trouble finding sitters for, so if we ever to go to DH's friend's caravan or weekends away, he is the most likely to come with us and the crate makes that much easier. While I can trust him not to pee all over my house, if we took him somewhere new and left him alone, he almost certainly would leave his mark there and over there and a bit more over there and some in the corner over yonder...
It's also handy if we ever get any short term, emergency fosters who may not be dog friendly. When that happens we operate a kind of double door system, whereby the hallway is a no go area and dogs are kept in separate rooms, with the hallway as a buffer zone in case of escapees. However in order for the front room dogs(s) to get to the loo they must pass through the back room, so the back room dogs(s) get safely crated before the front room dog(s) is allowed out there.
