I did not give a five star rating at this time because I have only been using the product for two weeks not enough time to expect dramatic results. What I can give 5 stars to is the efficient way the product transaction was handled and how quickly I received it from VetDepot!

One of my rotties has severe arthritis and has been taking expensive medicine like Previcox every day. Since I've started using this brand's LIQUID version, he only needs Previcox here and there, maybe a handful per month.

I've tried this brand's tablets and other forms, but ONLY THE LIQUID version has had a dramatic impact. Highly recommend this brand and the liquid version. The arthritis meds are very harmful to dogs and this can cut down on the use of them drastically. My doggie is 8 years old and bounces around like he did when he was 8 weeks old!

I have now been using this product for a year. I am really pleased with the results. My 16 yr. old cat has much more flexibility in her hind legs which were quite stiff. Great value for the price!
