Renum is recommended in cases of renal insufficiency in dogs. Renal disease is a common and serious clinical process in dogs. There are many causes that can lead to renal dysfunction. This is characterised by the loss of metabolic, endocrine or excretory function of the kidney. Renum plays a protective role against kidney damage secondary to urinary tract stones. It is a combination of Coenzyme Q10 (ubiquinone) with the four tocopherol forms of vitamin E: alpha-tocopherol, beta-tocopherol, gamma-tocopherol and delta-tocopherol (tocopherol). It can be administered mixed with the ration or directly into the animal's mouth. It is recommended to be administered together with the ration to ensure its correct absorption.
