Add all ingredients to a large mixing bowl. Mix or beat until well combined.
Sprinkle work surface with additional flour, and roll out dough using a rolling pin until about 1/4 inch thick
Cut the dough into shapes using a cookie cutter of choice and place onto a cookie sheet
Bake for 15-20 minutes (I find that 18 minutes is perfect in my oven), remove from oven and let cool
Notes
Be sure your peanut butter does not contain xylitol which is extremely toxic to dogs. It’s best to stick to organic or natural brands and as always read your ingredient labels!
