Neighbor has a Rottweiller in a pen, I used to have a Labs, and even I would hate to feed his dog! Anytime he sees me, he makes a straight line and I look for cover...... he'll knock me over trying to lick me. LOL He gets all my bones. But when I gave the neighbor some of the smoked skin off the bacon for Packman, he was amazed, (the neighbor was, not the dog, well maybe they both were). It was the first thing the couldn't crush and eat in under a min. Dog loved it. Carried it around for days. So every once in awhile I'll dig a skin out the freezer and share it.
You should never feed another man's dog, but I am guessing that the dog knows where they come from.
Oh and never give a puppy smoked fat especially if they are an inside dog.............. Ewwwwwww.
