The nice thing about dog biscuits is that you can improvise a great deal with them, incorporating just about any element that your dog either likes or that you want to add to his/her diet. That said, feel free to swap ingredients in or out of this basic formula. As long as you have enough liquid to bind the dough and enough fat to keep the biscuits from becoming absolute rocks, you’ll be in good shape. Start by preheating your oven to 400 degrees. Combine your wet ingredients in a bowl or measure:
Stir them to combine:
Then combine your dry ingredients…
Add the wet stuff to the dry stuff.
And using a spatula, bring the dough together.
Turn the dough out onto a well-floured board.
Roll the dough out to about 3/8″ or 1/2″ and cut to your desired shape.
Lay them out on a parchment-lined baking sheet…
…and bake for 20 minutes. Turn off the oven and leave the biscuits inside to bake and/or dry out as the oven cools down. Cool completely and store in an airtight container.
