This set consists of Piper pawzles only and is a great addition for both increasing the number of combinations on your base and increasing the difficulty of your set-ups.

Piper is a pawzle that takes up 4 spots on the base and offers 4 treat-hiding compartments. It requires unlocking the sliders before lifting the lid to uncover the treats beneath. Piper allows you to change its difficulty as your dog develops! Start by removing both sliders and make Piper an (easier) option, similar to just having 4 Zoey pawzles. Then add 1 or 2 sliders (included with each pawzle) to lock the lids and make things increasingly difficult. The slider can be unlocked with a dog's nose, tongue, or paw.
