I have the eagle motion pack and really like it. However, if you want a real extensive range of choices check out Credo Interactive (I believe www.charactermotion.com) I got the poser animals set for about $60.00 and there are dog, cat, and horse bvh files for most every base animation set you need. String them together, a couple of hours in the graph editor to smooth the transitions and you're launched. Would save days, in my opinion. There is also multiple, multiple poser people animation sets, too. I got the animal collection because I got into a complete spin trying to get a natural looking walk. Drove me up the wall; how animals can do it properly is a mystery to me; they make it look easy...
