Pure Protein for Sensitive Paws. Struggling to find a treat that won't trigger an allergic reaction? Donegal treats are the ultimate solution for the sensitive dog. Every product in this collection is 100% single-ingredient, meaning no hidden grains, soy, corn, or artificial binders. Whether it's their air-dried whitefish or premium beef, you know exactly what your dog is eating. At Fetch Natural Pet Market, we recommend these for "exclusion diets" and for owners who want to avoid the inflammatory fillers common in processed biscuits.
