Commercial dog biscuits contain artificial preservatives that help the biscuits last longer. Like anything artificial, however, they are also bad for your dog's health. Fortunately vitamin E, found in cinnamon, and vitamin C, found in strawberries, both act as natural preservatives.
Preheat the oven to 350 degrees Fahrenheit.
Add all the ingredients to a mixing bowl and mix well.
Make a well in the center of the mixture and pour in a little water. Mix the ingredients until it becomes a dough.
Take the dough out of the bowl and knead it on a flat surface for about three minutes or until it has the springiness of elastic.
Sprinkle a good measure of flour onto a surface and roll out your dough with the rolling pin. Add more flour if the dough begins to stick. Roll it out until you think you can cut out about five or six biscuits.
Cut out the biscuits using cookie cutters of your choice.
Line your baking tray with parchment paper and lay the biscuits on top. Place in the oven for 10 minutes.
Allow the biscuits to cool and then put them in an airtight container. If you store them in the fridge they will last even longer.
