I made a variation of these dog biscuits last Christmas for a few special dogs in my life. All the dogs enjoyed them, as well as a couple of my friends who tested them for the pups :) They really are more of a peanut butter banana cracker, so these are approved for dogs and humans!
This recipe is super simple too, just mash up:
2/3 cup peanut butter
2 cups wheat flour
1 cup wheat germ
Then roll it out on a floured surface and cut your shapes out. I found a dog bone cookie cutter at a craft store for about $0.75.
Put them on an oiled cookie sheet and bake for 30 minutes at 350°F.
Let cool and watch your dog devour them!
