Groov is a first-of-its-kind crate training tool that helps pups love their crates. It also doubles as a delicious pupsicle (comes with a freezer shell). Whether you are introducing your puppy to a crate for the first time, re-training an older dog, or just giving your pooch a special treat to enjoy safely in the crate, Groov makes crating easier and more enjoyable for everyone. Groov is made from high-quality, food-grade, BPA-free all-natural rubber, and is ergonomic and durable. Best of all, Groov is easy to use and is compatible with the Revol crate and most traditional wire crates. Groov is tested to meet the relevant performance requirements and chemical limits for children's toys (per ASTM F963). Safety Tips Groov is not a chew toy. For your pet’s safety, do not let your dog bite or chew Groov. Groov is intended to be used with a spreadable treat. Using Groov without a spread may result in chewing. Do not leave Groov with your pet unattended.
