Who says doggies don't go to school? Brighten up their sniff lessons with the colorful and super squeaky crayons! Stuff treats into the crayon box and fill it up with the crayons for a burrow and nose work test, I hope your pups will all get an A+ here! Approx. 4x7" Each pup plays differently and we recommend you to keep a close watch particularly during the first time a new play object is introduced. No toy is completely indestructible, so please supervise the play to ensure safety if you know your pup is not gentle with toys.
