2 1/2 cups wheat flour
1/2 cup powdered dry milk
3/4 cup water
1 egg beaten
Preheat oven to 350 degrees. Combine flour and dry milk. Mix in egg. Add water (a little at time) so that mixture forms a ball.
Roll out dough 1/4" thick. Cut out shapes with a biscuit cutter.
Fill with meat ( leftovers work great) sprinkle with a few chopped tomatoes and little grated cheese. Make sure the vegetables you use are dog friendly. Keep in mind, dogs can't tolerate salt and shouldn't have sugar.
Fold the dough in half and seal by pinches the edges together.
Pop them in the oven and bake 17 to 20 minutes. Brush the top with a beaten egg to give them a glossy sheen.
