This stuff works amazingly well and fast! I rarely write reviews. I am not one to post things, but I felt compelled to let other dog lovers know that Dog Pain Away really works. My Great Dane was to the point it took him several minutes just to sit down completely and he was having trouble getting up, not running or energetic anymore. After a few days on this, he was like a puppy again. He is running, energetic, and can sit and get up without difficulty.
