Just to let you know how impressed I am at how well red light therapy is working on my dog. He suffered a cruciate ligament injury in his right hind knee 2 weeks ago. He was in such pain he couldn't even put the leg down and was hopping on 3 legs. We even had to bring his food to his bed because he didn't want to get up. After less than a week of treatment, he's up and about, playing, walking And even running. He's definitely feeling much better! I'm amazed. Thank you :)"
