We adopted a dog-lab from a shelter years ago with hip problems. Her owner had to turn her in due to downturn in the economy/finances but wrote many instructions/info for whoever adopted her. She was in a dog kennel during day. We have farm and she was able to stay out and swim in a pond and we fed quality food but we concerned about her hips which seemed sore and decided to try cosequin and within a few days noticed improvement and she was happier and started swimming in our pond and we have continued to use it throughout the years. Whe started walking with the rest of the pack around the property and at times feels well enough to jump around on her back feet playing with the other dogs. It certainly has worked for this dog with swimming in the pond/exercise as tolerated.
