Does anyone else feed these to their dogs? I have for years without any apparent problem. They LOVE to nibble out the marrow in the middle along with any fax and meat on the edges and then they knaw on the bones for a bit. I figure it must be nutritionally beneficial for them as well as good for their teeth and it keeps them occupied for 30 minutes, which helps alleviate boredom and anxiety. In fact for people whose dogs have anxiety issues I recommend giving their dog one of these when leaving their home. The dog will be so into their bone that they won't be worried about their owner leaving. I get them in the meat section of my local Publix supermarket stores.
