【Soft and Safe】: The dog toothbrush is made of tear-resistant thermoplastic rubber, extremely durable, more reliable than regular rubber, and has no bitter taste or strong rubber smell. The dog chew toy is not hard and will not hurt the dog’s teeth. 【Perfect Size】: Size of the molar stick about 15 x 5 x 4.5cm / 5.9 x 2 x 1.8 inches (for 25-70 lbs). Comes with 2 cleaning brushes to make RuiChy dog toys easy to clean. It is only suitable for small and medium-sized dogs, not for large aggressive chewing dogs. 【Unique Design】: The dog toothbrush is specially designed with serrated grooves and can clean the molars more effectively. Dog’s teeth perfectly fit into the grooves for a comfortable chewing and brushing experience. 【Snack Stick】: Shredded food or snacks can be placed in the inner aisle, allowing the dog to use it as a food stick. After putting toothpaste or favorite food on the grooves, let your dog brush his own teeth and freshen his own breath! We recommend cleaning it before
