I also like to give my dogs raw bones for recreational chewing.

I usually give them beef marrow bones or knuckle bones. They last for a couple days, then I throw them away. With the marrow bones you might want to scoop out the marrow in the middle as it can sometimes be too rich for a dog's stomach to handle at first.

Here are some pics of my dogs enjoying their bones.





Here Clipse is chewing on a deer rib bone. The smaller ribs he just ate, but the larger ones were good for chewing.
