Query: my dogs were running up and down the stairs like they were puppies again

I decided to try these Cosequin Minis when My 10 year old Chihuahuas started having troubles going up and down our steps. After a week of taking the Cosequin Minis, my dogs were running up and down the stairs like they were puppies again. This stuff really does help their joints!
