Petstages ORKA Bone offers an appropriate toy for dogs that love to chew. Its solid construction is durable, yet "chewy", helping to curb a dog's urge to chew. The ORKA material is durable, non-toxic, synthetic rubber. The bone is designed with multiple textures to massage gums and keep your dog's interest. The cotton rope and raised textures help clean teeth and gums to enhance dental health, and the flat shape helps exercise jaw muscles. Available in regular and mini sizes.
