Thank you for viewing! [Prevents Damage to Toys and Furniture with Sound] This toy has a sound device inside, and it makes a "squeak" sound when your dog bites it. This helps dogs focus their attention, preventing them from destroying furniture or items used by humans while they play. [Cleans and Protects Dog's Teeth / Safe and Secure Fabric / Play Alone] This is a smooth-textured dog toy made of natural, non-toxic latex. It has excellent elasticity, is durable and hard to break, and is produced with the same quality as children's products, ensuring the safety of both people and pets. In addition, the surface has a bumpy design that can massage the dog's gums and clean their teeth. Because it's a ball design, it can roll around, so your dog won't feel lonely while you're away. [Lack of Exercise / Stress Relief] Chewing and playing with the toy can also relieve stress. When the owner throws the toy, the dog instinctively chases after it. This process properly solves the problem of lack of exercise and also helps maintain your dog's health.
