Ellie plays a great game of "tug" and is oh-so-snuggly at night. 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 that 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. The outside layer is made of a tight-woven sherpa style fleece ? the result is good flexibility with high durability. The inside layer is made of tight-woven brushed fleece of the heaviest weight and highest durability. All material seams have two rows of stitching, are covered with a layer of soft, flexible material and sewn together with another two rows of stitching, creating a soft and durable toy with no hard edges. These toys are machine washable (air dry) and float.
