With three large Alaskan Malamutes including two with hip dysplasia I compared several premium foods that promoted healthy joints.  I found Nutro's Natural Choice Large breed formulas to be the best. 

 I have fed them the adult formula, weight management formula, and they currently are on the senior food.  The Nutro products I have used offer both glucosamine AND chondroitin. 

I would recommend this product line to large breed dog owners.  The ingredients are also good for aging joints and arthritis.   The Natural Choice foods also promote healthy coats and I have noticed an improvement...
