Bones are a healthy dog treat that clean and strengthen their teeth and keep them entertained. While there are many types and flavors of bones available at grocery and pet supply stores, you can also cook bones at home to give to your dog. The main purpose of cooking the bones is to kill off any bacteria that may cause stomach upset for some dogs, not to brown the bones. When cooking bones, choose large ones so that your dog does not swallow them.
Go to the meat counter at a supermarket or to a butcher shop. Purchase the largest bones they have that are still whole. Some good bones to use are cattle, deer and elk bones.
Spread a layer of aluminum foil onto a cookie sheet or a shallow baking pan.
Place the pan into an oven set to 350 degrees F and allow the bones to cook until the tops start to dry out. This can take between 10 and 15 minutes depending on your oven.
Open the oven door and use a pair of tongs to turn the bones over. Re-close the over door and allow the bones to cook until the other side is no longer wet, but has not begun to turn brown.
Remove the bones from the oven and turn it off. Allow the bones to sit for one hour until they are room temperature before giving them to the dog.
