Initially, over a period of 4-6 weeks, dosage is recommended at 2 chews per day. Over time, as your dog’s comfort and mobility improves, suggested maintenance levels are 1 chew per day. The maintenance level can be used long-term on healthy dogs to help support their joints. An individual dog's needs may vary. Dogs on a maintenance level can be increased to the initial level as needed, for example, on weekends or other times when they are more active to provide support to the joints.
