Labs will eat ANYTHING. A couple of years ago, I was in a vet hospital waiting room, and a lady sitting next to me was there with a Lab. It had eaten its nylon leash. In three bites. One bite had passed through on its own, another bite had been fished out the dog’s back end a couple of days earlier by a vet using some sort of “fishing” tool, but the third bite was firmly stuck way up in the intestinal tract and was going to have to be removed via major abdominal surgery.
My grandmother’s lab—at different times—ate a full package of paper napkins, rocks, and a partial bag of fertilizer, which almost killed her. Dopey dog.
