The core advantage lies in the triple design of "durability + oral care + interactivity": first, the reinforced dual-material structure delivers extreme bite resistance. Unlike ordinary plush toys that tear in hours, the toy features a TPR rubber core (Shore hardness 85A) wrapped in tightly braided natural cotton rope - the rubber core resists strong biting force, while the braided rope prevents fraying and withstands 500+ hours of chewing by medium breeds like Labradors. The cotton rope undergoes 3000 times tensile tests without breaking, and the TPR rubber is flexible enough to avoid damaging dog teeth while being tough enough to resist punctures. Second, the integrated teeth-cleaning function reduces plaque by 65% with every play. The braided cotton rope has a textured surface that acts like a "dog toothbrush" - as dogs chew, the rope rubs against their teeth and gums to remove food residues and tartar, while the TPR rubber surface has raised massage points that stimulate gum blood circulation, preventing gingivitis and bad breath. Third, the leaky treat design turns play into mental stimulation. The ball has 6 evenly distributed treat holes (8mm diameter) that fit most dry dog treats or kibble - dogs need to roll, shake, or chew the ball to get treats out, which relieves boredom and separation anxiety by keeping them occupied for 20-30 minutes per use, reducing destructive behaviors like furniture chewing. Humanized details enhance playability and usability for both dogs and owners: the built-in cotton rope loop on top allows for hand pulling, turning it into an interactive tug-of-war toy that strengthens the bond between owners and dogs. The 8cm diameter size is perfect for medium to large dogs (weighing 10-30kg), with a lightweight design (120g) that won't tire dogs during play. The natural cotton rope is absorbent and can be soaked in water for teething puppies to soothe sore gums, while the TPR rubber is waterproof and easy to clean - just rinse with warm water and air dry to remove saliva and treat residues. Unlike noisy plastic toys, this rope-rubber combination produces minimal sound, making it suitable for indoor play without disturbing neighbors.PlainCotton
