Patented products, This product subverts the traditional installation method of suction cup rope balls that requires manual squeezing of the suction cup. It innovatively adopts a 3rd-generation suction cup with a vacuum air pump. One side of the suction cup is equipped with an air extraction button; pressing the button repeatedly several times can complete the installation, and the vertical pulling force can easily reach more than 130kg. The other side of the suction cup is an air release button; one-click air release allows easy removal of the suction cup. All the ropes of this product are made of 7*7 rubber-coated steel wire ropes, eliminating the problem of being bitten off. This product can stimulate dogs' enthusiasm for playing. As a multi-functional pet toy, it integrates multiple functions: pulling/tug-of-war, squeaking, food-dispensing, molar grinding, and bouncing. The molar ball is also attached with a dog chew cotton rope, bringing multiple usage experiences to dogs through its multi-functional design.
