Preheat your oven to 350° F / 180º C and line your baking tray with parchment paper.
Put the oats in the blender and blend until you get an oat-flour texture. Take about 3 tablespoons out of the blender and save for later.
Add the turmeric to the flour and blend until mixed.
Add the egg and pumpkin puree to the blender and blend until you get a doughy mixture, similar to a cookie dough.
Flour your surface with the oat flour and shape your dough into a ball.
Roll out the dough until it a bit thinner than ½ inch thick and cut out shapes with a cookie cutter. You can make smaller o bigger sized treats according to your dog's size, cutting it in squares with a knife will also work.
Re-roll out the scraps and repeat or cut them into small pieces to make training treat bites.
Place the treats on a parchment paper-lined baking tray, they don't spread much so they can be quite close together.
Bake for 15 to 20 minutes.
Once the treats look dry and crunchy but not too dark, remove them from the oven and transfer them to a wire rack to cool.
Let your puppy enjoy the treats over the next days! Store them in an air-tight jar or zip-lock bag. They can also be frozen if your puppy is not going to have them all in a few days.
