Preheat the oven to 350°F and line a baking sheet with parchment paper.

In a medium bowl, whisk together the whole wheat flour and baking powder until well combined.

In a separate small bowl, whisk the egg and unsweetened applesauce until smooth.

Pour the egg and applesauce mixture into the dry ingredients and stir until a shaggy dough forms.

Add the water, 1 tablespoon at a time, mixing until the dough comes together into a soft ball that is not sticky or crumbly.

Transfer the dough to a lightly floured surface and knead gently for 1 to 2 minutes until smooth and pliable.

Roll the dough out to about 1/4 inch thickness and shape it into a large bone, or press it into a bone-shaped pan.

Sprinkle the shredded low-fat, low-sodium cheese evenly over the top of the shaped dough, pressing it lightly so it adheres.

Place the bone-shaped pizza on the prepared baking sheet and bake for 18 to 20 minutes, until the edges are lightly golden and the center is set.

Remove from the oven and allow the pizza to cool completely on a wire rack before serving to your dog.

Slice the cooled bone pizza into 4 portions or into small cubes for training treats, and serve in appropriate amounts for your dog’s size.
