Natural Product Information
Wonder Bars are individually hand-poured. You may occasionally notice small bubbles or a light, icing-like appearance on the surface.
These are natural characteristics of the collagen-setting process and do not affect the flavour, quality or performance of the chew.
Storage
Store in a cool, dry place away from direct sunlight.
Please note: This product is intended for dogs only and is not for human consumption. Always supervise your dog while chewing and remove any small pieces that could present a choking hazard.
