The Goughnuts Tug MaXX ($34) is a great tug toy; there's different sizes for medium to giant breed dogs, according to Dr. Hall. "I recommended this for a few reasons being that it's very durable for hours of playing tug-o-war with your dog," he said, "Or even a casual evening of being chewed on non-stop. But also, it's made of tough rubber so it's easy to clean and is comfortable to hold in your hand as you're tugging away."
