Hi Sterling Silver,
The company that I work for is called Regeneus. We have been doing stem cell therapy in dogs in Australia for the last 3 years (called AdiCell) and have treated over 350 animals. We are now doing work as well on people with arthritis (called HiQCell) with very similar results.
We try hard to track every dog that has been treated (some owners do not respond). Of these dogs, over 80% of owners think that their dog has improved. The biggest improvement seems to be in terms of pain relief, however there are also improvements in lameness, endurance, mobility, and quality of life.
Have a look at our website for more information. www.regeneus.com.au
