TROVET Hypoallergenic HPD is hypoallergenic food that contains all essential nutrients. The unique combination of horse and potato rarely cause a hypersensitivity reaction. This is partly because TROVET Hypoallergenic HPC (Horse) consists of only one protein source (horse) and carbohydrate source (potato). By feeding your four-legged friend a hypoallergenic diet, you prevent immunological reactions (food allergy) and non-immunological reactions (food intolerance) in the form of skin or gastrointestinal complaints. In addition, it helps reduce annoying allergy reactions, including scratching, scratching or biting.
