If you have a meat market near you, I would suggest checking it out. While you can get a cheap bone for $2-$3 at Wal-mart, my dog can finish one of these "bones" in a matter of 10-15 minutes. At our local meat market they sell bones filled with a meat mixture and bone marrow. My dog will work on the bone for 3-4 hours until she decides to stop. These are only $2 here. They are really affordable. The only thing I don't like about them is that my dog can't actually chew the actual bone, she can only dig out the inside. However, the $2 is definitely worth it. See if your local meat market has these. You won't be disappointed! My dog goes crazy over them.
