Glucosamine, also referred to as glucosamine sulphate is an added supplement found in some specialist dogs foods, particularly foods for senior dogs and puppies. Glucosamine is also used as a supplement for human consumption, too.
Glucosamine is believed to aid the development, and to relieve problems in the animals joints. These benefits are important to puppies, as they are going through their fastest stage of growth and may aid the 'growing pains' which commonly originate in the joints. In older dogs, the potential benefits to provide support the the dogs joints is necessary as they're vulnerable to weakness and poor mobility.
Glucosamine is commonly used with Chondroitin Sulphate as a supplement to treat osteoarthritis.
