I do baked items for my out of state family every year. This year I added a bonus for those with pooches.
2 cups whole wheat flour
1 tablespoon baking powder
1 cup natural peanut butter (grind it yourself for extra love)
1 cup skim milk
Additionally you can add:
Ground or sliced almonds
Carob chips (chocolate is bad for dogs)
Mix together. Prepare baking pans by lining them with parchment paper. Roll out and use cookie cutters to make shapes or a cookie scoop to make mounds (the bigger the dog, the bigger the scoop [Oh isn't that true for the other scoop too?]). Flatten the rounds with the bottom of a drinking glass that has been dipped in flour.
Bake for approximately 20 minutes at 375 degrees.
