My 33 year old new forest pony has suffered with allergies and general breathing problems all his life ( he came to me age 3months ) . Tried vet recommended products that cost a fortune and made little difference. Eventually discovered Feedmark and tried Clarity , which went nicely into his feed , and his breathing improved . Now , many years further on , his breathing is excellent and only occasionally , in very adverse conditions , does he show signs of distress .
Good stuff . I thoroughly recommend it…..it does what it says on the ( very large ) tin !
