DS is a patented, scientifically researched nutritional
supplement 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. While he used to be eager to play,
now he is content to rest. Even at younger ages some dogs are subject
to joint health concerns which affect flexibility and mobility.
