Preheat oven to 325 degrees.
In a large mixing bowl, mash a very ripe banana with a fork. Add the pumpkin purée, applesauce, flour and one Tablespoon water. Mix well.
Dust your workspace with one Tablespoon of the whole wheat flour, and place the dog biscuit dough on top. Then knead 8-10 times. Add one Tablespoon of water if the dough is too dry.
Line a cookie sheet with parchment paper.
Use a rolling pin to roll the dough out to about 1/4" thickness. Cut into dog bone shapes with your cookie cutter, and place on the lined cookie sheet.
Bake for 20 minutes. Then cool on a wire rack.
Store in an airtight container for up to 10 days.
