100% BEEF: When we say 100% Beef, we mean it. All of our Beef tripe is completely natural, made from a single source ingredient. Free from all additives, Preservatives, Flavourings, Grain & Gluten. A great natural treat packed with flavour that will leave you dog drooling. These can be smelly, which is great for your dog but not so good when feeding inside the house, we recommend feeding this treat outside and keep stored inside the clear bag provided.
