Love this stuff, was a buyer for several years about 7 years ago for my Aussie. She was on this for several years during her 17 year lifespan, and it made a tremendous difference in her movement and comfort. She would dutifully lick it up every day before her meal, I could tell she didn't really like the taste, but she compelled herself to drink it - as if she knew it was helping her. When I would run out, I would notice a difference in her, even though she never went longer than a week without it. Now I have a new Aussie, she just turned 8, and though she has shown no signs of arthritis, I decided it was time to put her on it since I knew it made such a difference. My mother was also a buyer and she said she noticed a tremendous difference in her hip pain and arthritis and she had already been taking glycosamine supplements before she started the flexicose. The only disadvantage to this product is that it seems kinda expensive, but then it is MUCH better than any glucosamine supplements.
