Artificial glucosamine dosage for dogs is manufactured in laboratories with the raw materials being shell fish, crustaceans and skeletons of sea animals. Natural glucosamine is made in animals’ bodies and is one of constituents of cartilage which forms a protective coat in animal joint bones to protect them from friction while moving. Lack of glucosamine in an animal’s body is the cause of dry bones, a condition which results into inflammation due to tissue damage in joints. As a dosage, glucosamine not only protects the dog from arthritis but also helps improve general health of a dog by contributing essential minerals to the dog’s bloodstream and help the dog recover faster as well. Other functions of the artificial glucosamine include improvement in joint flexibility, joint maintenance, and relieving pain. Incase you need to purchase glucosamine for your dog, you are advised to pay a visit to the nutritionist or veteran who will either sell it out to you or direct you to the right place and for the right product.
