I've heard of making your own dog biscuits but how?
How do you make homemade dog biscuits?
There is a kit at pet smart. It has everything you would need except for the fun of making biscuits and the dog! You have to supply those yourself (and the oven!)! Enjoy
Maybe a pet food website has a recipe.
There's a bunch of recipes on some of Google's sites. I've seen lots of them. We make some but mostly with beef liver and little grains at all.
shred dog, add 1tsp. per biscuit
