OK I know that you supposedly aren't supposed to feed dogs bones.
But Lucy..... she eats pine combs , chunks of apple & hickory wood ( prefers apple)
Crawfish heads , bricks, hoses , beer cans, brought a portion of a deer carcass & ate a lot of it!
The huge rawhide bones last 45 min)
But beef rib bones are tough & she loves them
One bone will last a day!
I'm cooking beef ribs tonite!
