Collory Silicone Mini Bone Baking Mould for Dog Biscuits and Treats, Chocolate Mould, Non-Stick and Food-Safe (BPA-Free), Silicone, Set of 2: Mini + Large Bone Shape, 39,5 x 28 cm

Collory molds are featured on the Facebook site Pyramid dog treats. There are tons of recipes. We like their forms because the finished treats pop right out without sticking, and the forms are made for baking. They make adorable bones, as well as treat-sized hemispheres (little round ones.) They've said they're coming out with some new ones in Spring 2020. We can't wait!
