For dogs with food intolerances and allergies, this is an ideal snack as it consists only of venison. The use of only one protein source minimises the risk of a food hypersensitive reaction in your dog. These snacks can also be a godsend in an elimination diet. After using them for 3 and 8 weeks, you can judge whether the snacks provide relief. When the hypersensitivity symptoms disappear, the snacks can be used for an unlimited period.
