Take the 'dog food' out of the food container and flatten to make a 1cm thick layer of 'dog food.' Use the cookie mold to cut out a dog's treat. This is exactly the correct quantity of material you need to feed the dog, (remove all surplus material). Take the 'treat' and use your fingers to push it inside the dog's mouth. Use the feeder bone to push the 'treat' with a slow, turning movement (until you cannot push any further) in the correct position inside the mouth.
After playing, store 'do food' in its packet with seal tightly closed to prevent dehydration.
