W'Zis 100% natural, grain-free, plant-based treats have a deliberately firm texture and angular profile to prolong the eating time and promote teeth cleaning. But you can afford to be generous; these healthy morsels only contain 1 calorie per treat, perfect for training. After some consideration, W'Zis decided not to mirror the unique aroma of lamp posts. These have a more gentle flavour profile. The splendid blueberry colour comes from the inclusion of purple sweet potato.
