Feeding raw bones?

 If outside in the winter doesn't work you can teach your dog to chew his bone on a mat. I use a bath mat that can be thrown in the wash.

I feed outdoors in through the year except for the coldest of winter, but it's easy enough to feed indoors like Denise said by feeding them in their bed or on a mat that you can just throw in the wash.  I have one old comforter that is folded up into a bed that the dogs can lay indoors in a sunny spot and chew bones on the wet or cold days.

 I use a local meat market and buy some pre-cut, and have others cut for me to size. It takes some getting used to the routine, but I buy in bulk so I only actually "shop" every month and a half to two months or so. They're usually happy to see me come in because I leave with big purchases!

I just get the beef marrow bones from the local grocery store here.  They usually have them frozen.  They are very inexpensive.  And, you can select one cut a little smaller one to fit his mouth better.  They really work great.  I have to literally put old blankets and towels down in almost the entire room when she has one.  She never picked up on the stay in one place thing.   I'm sure you've heard this before but scrap the marrow out so it doesn't upset his stomach.

 Bugsy won't eat a raw bone outside - he buries them over and over so I feed him raw on a bath towel and he is super about staying on it.

I get inexpensive knuckle bones from a Chinese supermarket as they are the only ones locally that have full bones which I ask them to cut off the knuckles.  I don't feed Bugsy the marrow bones because he tries to crack them open which is asking for a broken tooth

 It would be better to feed Benny raw bones outdoors to save the bother of cleaning up afterwards. Alternatively, you could train him to chew the bones on an old washable mat.
