Made by Sniff and Shift in Malvern, PA

The freeze dried side runs from beef heart and tripe to shrimp, scallops, blue lipped mussels and baby octopus, then sardines, minnows, anchovies and pink salmon, with quail eggs, frog legs, cheddar cheese and a dog ice cream in fruit and peanut butter flavors. The air dried side is chews: chicken feet, duck feet and duck necks. Beef comes from a Pennsylvania farm and chicken and cheese from New York, while the seafood and the exotic proteins are imported. Beef liver has its own home at the Sniff and Shift liver site.

Where a label reads single ingredient, the product page says so too. To shop the house treats made with Pennsylvania and New York inputs, see treats made in Pennsylvania.
