I have been using the Photon torch on my Mum’s eight year old Rottweiler with remarkable results! Misha had done her cruciate ligament and required surgery two years ago. She never fully recovered and always walked with a limp. She also became older than her years and stopped playing with other dogs. I have been using the wand on her for about eight months, every six weeks. She no longer has a limp and plays like a two year old with my three year old Labrador. Her demeanour has completely changed – it is amazing! I also use it on my Labrador who had developed soreness in her hind end. She too has fully recovered and no longer shows any sign of soreness. I highly recommend this torch for any kind of soreness in dogs.
