Nekton-Dog-H is a vitamin supplement with a high percentage of biotin. Biotin will often correct many skin and coat issues in dogs. Because biotin often cannot be synthesized by dogs themselves, it is important to make sure they obtain enough of it. Symptoms of biotin deficiency include dull, brittle and dry hair, premature graying, bald patches, pale and scaly skin and even eczema in severe cases. Nekton-Dog-H will ensure your dog is getting an appropriate amount of all the necessary vitamins and extra biotin to improve skin and coat. Nekton has created a range of dog and cat supplements because no one supplement can cover all requirements in all situations. Nekton-Dog-VM is a vitamin, mineral and trace element supplement for dogs of all ages. Nekton-Dog-V is a vitamin-only supplement available for dog owners who need to tune their dog's unique vitamin needs.
