Ours also eat carrots, and the diabetic dog has survived 5 years now on lean meat, brocolli, cabbage, (cooked), baked yams, and a few other items. We bake them chicken regularly and feed a high quality dog food.
My SIL had two Newfies, one recently passed away from old age, I think. I think they’re gorgeous. She has always had them shaved in summer, cuts down on the shed problem. They were always good natured, but I imagine they might eat an acorn...:-D
