Finally! We have been working on this command for a good month now, and she was having quite a bit of trouble with it. From my understanding, "backing up" is not a normal canine behavior, so many dogs have problems with it because it does not fee comfortable to them. Needless to say, Tyanna was having this problem, but in the past few days she has been showing quite improvement!! Here's a video of her practicing her "backs". They still need a little cleaning up. And oh, please excuse my messy messy room!
