Dogs, especially labs and Goldens, will eat anything they see that even looks like food, to punish them for that very doggie behavior is simply evil.
We had a Newfie mix, I had just cooked a roast and had it on the carving board. My son called out to me, left the kitchen for what seemed like a minute, came back and the meat was gone, not even a dripping left. Stood there for a second completely dumb struck.....looked over and there was Zack just sitting in the corner. I was more amazed at the speed he devoured it than mad.
