Green beans are high in fiber, vitamin K and vitamin C — all good things for your furry pal. They're also easy to digest and can even help aid in digestion for pets with more sensitive stomachs. Have an overweight pet? Even better. Veterinarians suggest replacing a portion of your dog's food with green beans to fill them up with a low-calorie food. Just make sure you ease them into eating green beans. Feeding them too much could result in an upset stomach and diarrhea.
