Personally, I've thought about them ALOT! I pet one in a store once. They are so soft and it also, very gently nibbled my hand! You know like a dog will do when cleaning. Very cool!
I went as far as buying a book and reading about them. I think the thing that turned me off was, (I read) they are kind of skiddish of strangers.
Also, I was worried about what my dogs would do. If you get one, keep us updated.
