Preheat oven to 275°.
Wash the potatoes, cut the ends off, and cut the potatoes in half.
Lay the cut halves flat and slice the potatoes as thin as you can, length wise.
Put the slices in a gallon size baggie or a bowl and add the olive oil and cinnamon.
Layer parchment paper or wax paper on top of cookie sheets and separate the slices on top.
Bake at 275° for 1½ hours. (Length of time may vary depending on how thin the slices are.)
Let them cool thoroughly before giving to your fur baby.
Let your fur baby enjoy the yumminess. You will want to eat one too.
