I bought this rather unusual deck, featured in the video - The Dog Tarot, a few years ago now and it is useful for doing readings on dogs - obviously, but I have even used the deck whilst doing readings on people! The Dog Tarot deck has also been used to read on cats too.
Unlike a 'normal' tarot deck, this deck does not contain all of the entire set of numbered suits, but there are enough unusual cards to get a good clear reading if you are going down this route. I personally like the happy energy that I find comes through the deck. I would say The Dog Tarot is a cheerful alternative tarot deck all round really.
