Hi crazy4cats –
The glucosamine and chondroitin advertised in the Blue Buffalo foods is just marketing (a lot of brands do this), there’s not enough in there to provide your dogs with any benefits. There are 8 cups of food per kilogram and the bag states 400 mg. glucosamine per kg.. This equates to 50 mg. glucosamine per cup. The serving size for an 80 lb. dog is about 3 cups – this equals 150 mg. glucosamine. An 80 lb. dog would need about 1,000 mg. glucosamine for any therapeutic effect (this means the dog would need to eat 20 cups of food a day to get any benefits). Glucosamine is something that should always be supplemented separately if it’s something the dog needs.
