I had a similar experience with a friend’s dog when I shot a young rabbit too far back with a .22 Hornet.

The dog, a 3/4 Labrador 1/4 Collie, was usually very efficient but my friend’s puzzlement he seem to be spending quite a while fiddling around.

He eventually came back with a disgusted look on his face preceded by a fan of rabbit legs that he was gingerly holding by the paws with the sticky bits as far as possible from his muzzle!
