Nothing makes dogs jollier than play time. The Jolly Pets Jolly Bone is guaranteed for powerful chewers, so even the strongest dogs can enjoy hours of fun. This durable bone is made from a super pliable material that can be stretched, twisted, tugged, bounced and gnawed on, and yet always returns back to its original shape. It’s also ideal for water based catch and fetch because it floats in water. The ridges on the ends of the bone massage dogs’ gums so they can chomp away with ease.
