I found this site a while back...
http://www.gbronline.com/kcathey/goldenbone/dogbisc.htm
It has a zip file that you can download that has over 200 recipes I believe. It also has two b-day cakes. I will say though, I posted this before and someone mentioned that a lot of the ones on the site had garlic in them and dogs aren't suposed to have garlic. So just watch out for that, but they do have a lot that don't have garlic as well.
