Our 7 year old Labrador mix started licking her leg and we brought her to the vet. They tried to address it as a topical issue but it didn't help. We went back for x-rays and found out she had osteoarthritis. We were given a comprehensive plan filled with supplements, medicine and laser treatment for the pain. It worked very well and we have continued treating her and monitoring her pain levels. She is more playful and it appears her pain is well-controlled.
