Three of our single ingredient freeze-dried treats that crumble into the grooves of a lick mat: Cheddar Cheese Bites, Freeze-Dried Beef Heart (1.5 oz) and Freeze-Dried Sardine Heads. Crush a few, press them in, add a splash of water if you want it to freeze. Made in Malvern, Pennsylvania in small batches. Save 10% against buying the three bags separately.
