Step 1

Preheat your oven to 350F (180C). Line a large baking sheet with parchment paper or leave it dry (the treats shouldn't stick).

Step 2

In a small bowl or measuring glass mix the warm water and flax. Set aside for about 10 minutes to thicken.

Step 3

In a large bowl add the thickened flax mixture, apple sauce, peanut butter, parsley, and cinnamon and mix well. Add the whole wheat flour and mix to make a stiff dry dough (it won't come together just yet).

Step 4

Dump the dough and any remaining flour and bits from the bowl onto a clean work surface. Gather the dough and knead to incorporate all the flour. If your dough doesn't come together and is too dry, sprinkle over 1 teaspoon of water at a time until the dough comes together into a stiff dough.

Step 5

Use a rolling pin to roll the dough out to about 1/2 inch (1.3 cm) thick. Cut the dough into treats. I used this bone-shaped cookie cutter to cut out the treats but you could use any cookie cutter, or just cut them into squares with a knife or pizza cutter. Gather any dough scraps, and reroll to make more treats.

Step 6

Lay the treats out in a single layer on the baking sheet and bake for 45 mins - 60 mins until the treats are golden on the bottom and dry. Let cool before giving one to your pup. I like to let my treats cool on the baking sheet and sit out in the open overnight to dry even more and become more crunchy. Store in an air-tight container in the fridge for up to 2 weeks, or you can freeze them.
