I bought this for the reviews...  and they are spot on.  My 8yo pug was limping (she likes to jump off high places.  Pug body + dainty legs X age = frequent minor injuries!).  Just as promised, within 14 days, she was right as rain.  I will continue to use as a preventative measure.  Feeding my other 2 younger pugs the maintenance dose, while the older is on the dose for dogs w/ issues. That larger dose lasts up to 90 days, then moves to maintenance dose.  With 3 pugs once daily, this is 2/3rds gone after 5 weeks... that is my experience anyways.  Does smell like "henna" as one reviewer stated, which is not a bad thing.  My pugs did not even notice this in their wet food. Highly recommend.  At a minimum, it won't hurt.  But if you are looking for "just the right" product for joint issues, I'll go out on a limb and say:  Stop searching, click "add to cart" and be done with it!
