Preheat oven to 350°F.
Chop the freeze-dried apples into ¼-inch pieces.
In a medium bowl, mix together the eggs, applesauce, and peanut butter. Use a hand mixer or a large spoon for this step.
Add the rolled oats and apple pieces and stir to combine well.
Turn the dough out onto a smooth surface.
Using your hands, squeeze and combine the ingredients until you have a flat, smooth dough.
Flatten the dough evenly with your hands or a rolling pin to about ¼ to ½ inch thickness.
Using a cookie cutter, cut out the dog treats and place them on a greased baking sheet or use parchment paper or silicone mat to cover the baking sheet.
Bake for 15 to 20 minutes.
Place the treats on a wire rack to cool once baked.
