Our 10 year old amstaff has struggled with arthritis for a couple of years. It comes and goes. A trip to the vet and some pain medication usually gets him back on his feet but we were looking for something a little different.
So far I'm pretty impressed with this product. It seems to be working very well, it's only been a couple weeks, but I'm looking forward to seeing further improvements as he continues his doses.
Don't be scared off by the "different" ordering mechanism (borderline shady email money transfer?) - it seems a little suspect at first, but it's legit and the product arrived really quickly.
