Its funny how some dogs love crates and others hate them.
We've always used them for our pups, Sapphi being our first. She hated it, but had to put up with it.
Max loved his and Barney loves his. Because Barney has been wearing a bucket after his castration, he couldn't move in his crate without getting it stuck, so I got out Sapphi's old one (three different size dogs, three different size crates
) for him to use while he's wearing his bucket. From the second I got it out Max has been squeezing himself into it and then Barney gets in and sits on him.
