Tripe is the stomach of ruminating (grazing) animals such as cattle, sheep, and goats. It is rich in gastric juices, amino acids and other digestive enzymes. In addition to helping your dog digest and efficiently utilize the nutrients in his food, digestive enzymes also cleanse the body of toxins, parasites and fungus, as well as improve your dog’s metabolism, hormonal function and boost his immune system. Amino acids are crucial for muscular development and the other gastric juices are said to be the best cleaner for their teeth! Tripe also contains the optimum ratios of calcium to phosphorus and the essential fatty acids, Linoleic and Linolenic, in their recommended proportions. All the nutrients, vitamins, minerals, amino acids, etc. are natural, raw and unprocessed...no synthetic ingredients or preservatives. In this natural form, everything is easier for the dog's body to absorb and utilize. Sold in 2lb chubs. Keep frozen until ready to use. Just thaw and feed. FOR ANIMAL CONSUMPTION ONLY. As with all raw meat products, always wash hands, utensils and surfaces after use.
