I have to agree with you, there are pros and cons about the medication, but our Vet prescribed it for our 15 year old Schnauzer who could hardly stand up and slept all the time and was in pain. I could not believe the difference it made in her, all of a sudden she was up going down the stairs with the other dogs and slowly running around the yard with them. We were amazed, and we saw no signs of upset stomach and her appetite was good through out. After a year, she went into a decline and passed away, but during the time she was taking the medication, it gave her a new lease on life.
