My Vet recommended this and we bought one. It ain't cheap ($625) but it pays for itself fast considering we were paying $100 a month on hot laser treatments at the Vet.
Great for arthritis and much more.
It works on people and pets.
NASA uses it, our soldiers are using it and it is FDA approved.
"The use of light emitting diodes (LED) in the practice of medicine
has moved well beyond science fiction and into the real world. Soldiers injured by lasers in combat, astronauts in space and children in cancer wards are already benefiting from the healing properties of near-infrared light in ways that could only be imagined a few years ago. Several research projects at the Medical College of Wisconsin are at the center of LED treatment development and the application of new technology to a wide range of injury and illness. "
We bought one (Warp 10) and it is great for aches and pains and also for healing sores that Casey gets in her mouth.
Here is some info on it I found from different websites.
