This snuffle HAM & CHEESE features triangular treat slots between the layers to hold kibbles or bite-size treats as rewards. There's also a sandwich wrap for a burrow challenge for those smart ones! Approx: 4.5" x 4.5" or 11 x 11 cm 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.
