The Nylabone Moderate Flexible Dental Dog Chew Toy Bones are perfect for those who want to give their dog a little treat. These toys are made with a soft, yet durable nylon that is designed to last. The tiny bristles on the bones raise up during chewing, just like a mini toothbrush, which helps to keep your dog’s teeth clean and prevents tartar from building up. With a gentle to moderate chewing style, these toys are perfect for small breeds.
