The COMFY STRONG DOG toys are specially designed for very active dogs with strong jaws that tend to destroy regular dog toys within a matter of days. The COMFY STRONG DOG toys are made of exceptionally durable thermoplastic rubber (TPE). Thanks to their unmatched resistance to biting, the toys will last for a long time even if used by dogs that can quickly destroy a regular toy. They are made of certified safe material. In addition, with a treat insert placed inside the toy, your dog will never get enough of playing! This is an ideal solution, especially for those dog owners who must often leave their pets alone at home. Thanks to the captivating fun with the edible toy inserts, your dog will be busy playing rather than chewing on your clothes or furniture.
