Alpha rolling a dominant dog can lead the dog to bite - and when you alpha roll, your face is awfully close to their mouth. Kai's a sheltie, and they're generally gentle - not always as dominant as other breeds. That may be why you've never sensed the danger of such a move.

An alternative to alpha rolling a dominant dog is to have him/her go into a lot of downs for you every day. You have to be careful not to get your face close to theirs while enforcing a down, though.

Of course - Uabassoon won't benefit from that, since she won't have enough time with the dog for training.
