My Beagle is 13 years old and has been having some issues with her back leg. I started giving her these as a treat once a day. She has become a new dog jumping on the couch and running through the yard.
If I miss a day I can see the difference as she limps around.
I have been using Dr. Foster and Smith Joint Care 3 for over a year for my dog who was 13 and is now 14. The vet said it couldn't hurt It really works wonders for her and can notice a difference in her walking.
