To create the Pupsicles, we take the pork shoulder bones with a little meat still left on, lightly salt them, and smoke the bones alongside our smoked sausage. As a result the bones have that distinctive smoky Bourgeois aroma which dogs love as it turns out. Also, pork bones are soft so most dogs will eat them completely meaning there's no bone left dragging around the house or to run over with the lawnmower. There's no preservatives in this product, so put it in your fridge when you get it.
