Large. Green. MIGHTY® dog toys rethink durability and approach it from a new angle. Durability is created for each toy with multiple layers of flexible materials that move with the dog's teeth instead of tearing. Compared to other toys, MIGHTY® dog toys have no hard edges. The result is these toys do not promote chewing; great when you're trying to discourage chewing habits. These toys may seem plush on the outside, but all the durability features are internal making these toys soft, yet MIGHTY strong. Vulnerable areas are covered and sewn with a material binding that covers the original sewn edge. This extra binding creates multiple rows of stitching to hold the seams together. MIGHTY® dog toys are machine washable - air dry and they float!
