Couple of years ago I had some foxes in the woods around my house. Throughout the year I would occasionally put out a can a meaty dog-food for them. On several occasions I watched deer (usually an older doe) gobble up the dog food. At the time I figured she was eating it, despite the meat by-product, to get the corn, which is found in most canned dog food. Maybe I was wrong, perhaps she wanted the meat after all. Go figure.
