I think the guy who wrote that is an @$$, and he doesn't know the first thing about crate training. This is nothing more than propaganda for the purpose of promoting his own book.
I'm sorry, this is in no way criticising those of you who prefer NOT to crate, but it makes me mad to see stuff like this where someone is trying to explain crate training by making it out to be something it is not.
There is a heck of a lot more to proper crate training, than sticking a dog in a crate to keep him/her from pottying on the carpet. Anyone who just sticks their dog in a crate and leaves him all day is not using "Crate Training," but is simply "caging." He has a heck of a lot of nerve trying to confuse the two. We've used crate training since Chloe was a young puppy. She IS fully housebroken, and has been since 5 months. And by housebroken, I mean, she
doesn't go in the house. She scratches at the back door to be let out; other times, it's when we take her outside anyway. She has never eaten poop either. She is crated when we leave, and at night, we leave the door open on it during the day when she's hanging around the house, and she goes in her crate on her own when she wants to nap or is afraid of the vacuum or something. She sees it as a safe haven.
I'm sorry...you don't have to agree with the concept of crating, and I respect that, but PLEASE don't think that the methods this man is talking about is crate training. When he uses the "cage" terms, he should stick to that only, because the methods he refers to bears NO RESEMBLANCE to proper crate training.
And FWIW, I would have very little confidence in reading any book by someone who has to totally contort the meaning of another method to promote his own.
