A while back I had ordered "The Language of Dogs" from here: http://www.bluedogtraining.com/videos-dvds.html . I've watched it several times. It's a great video with some very clear footage of different canine body language, both distance-increasing signals and distance-decreasing signals. It also has some rather frightening footage of a couple horrible resource guarders, one of which lunges for her throat at one point.
I'm wondering if anybody has ever seen the other video, "Am I Safe?" I really want to order it but don't want to do so if it is similar to the one on body language, or shares the same clips.
Either way, I highly recommend "The Language of Dogs." There is a link to a trailer, but it doesn't really show you much. Trust me when I say 2 thumbs up!
