30 minutes of a dog chewing on a bone is 30 minutes of happily occupied, mentally absorbed, well-behaved dog. Better than having to buy one of them rawhide chew toys.
I give my dogs a pork shoulder occasionally. It takes them all day of chomping and chomping and chomping on it. At the end of the day, I throw whatever is left over out the garbage bin.
I am a firm believer of easy and simple means a lot lower chance of discouragement. So, I get a whole chicken fryer or rabbit from the store and give the whole thing to the dog without bothering to cut or do anything else to it. Dog teeth is very very efficient - more efficient than my knife in cutting up the thing.
The only reason I cut up meat at all is so they fit in the little daily containers that I put in the freezer so my husband/kids/pet sitter can feed the dog themselves. If it were not for that, my dogs are going to be eating for 4 hours trying to eviscerate an entire hog or some such...
