Both of my boys were introduced to a dog crate for house training purposes and occasionally I would use it for a safe house when small children would visit. Recently I have been hearing that the crates were inhumane for pets. I disagree with this thinking, for me it was a invaluable learning tool. Of course if you kept your dog in the crate for hours on in on a daily basis, absolutely that's inhumane and neglect. I'm sure others think differently than I do about them, they are in fact pens of a sort, if you look at them in that way. What are your views?
