The core of the Crusha is constructed of pet-safe thermoplastic rubber (TPR) that withstands all weather and, more importantly, teeth. Your dog will enjoy squeaking this cute critter. When removed from the soft body, the rubber core lives on as a hollow toy, ready to hold peanut butter, dog cheese, or the taste treat of your choice. Infused with Silver Paw's trademark Silvershield™ technology to keep odour-causing microbes away from the toy, and your pup.
