It was obvious that they looked and felt better. At that time, I was still taking them in for yearly veterinary check-ups. The improvement was so obvious that for the first 3 years of this incredible journey, my veterinarian at the time was constantly amazed at their condition. He repeatedly told me he had never seen such healthy dogs and cats. He wanted to know what I was “supplementing” them with. He was certain that I had found some “magical” supplement that was making them so healthy!
