I thought it was posted here before that it was the dachshund?
Well, yeah, somewhere I read the dachshund is most likely to bite. I guess what I was thinking in the statement was a 'protective' dog. Chi's are usually a 1 or 2 person dog & will have loyalty to them only. Granted, every dog can be an exception to the rule. Like Dachshunds, I actually know quite a few of them & never seen one bite or give reason to that list I read. It's that if you understand the breed, background, history, & it's initial use, you would understand how it ended up high on the list.
