Cosequin DS Chewable Digestion Supplement Tablets for Dogs are patented, scientifically researched nutritional supplements dispensed by thousands of veterinarians to help dogs maintain healthy joints. As dogs age it is common for their joints to become less flexible which impacts their mobility and quality of life; you may have noticed that your dog has difficulty walking up stairs or jumping on the bed. Healthy articular (joint) cartilage is crucial to joint utility, and these dog digestion supplements help support cartilage production and protect existing cartilage from breakdown. These dog supplement tablets are the only glucosamine/chondroitin sulfate supplements that have been shown safe, effective and bioavailable in peer-reviewed, published, controlled, U.S. veterinary studies.Note: This product may require up to 2 additional days for order processing prior to shipping
