Osteoarthritis in dogs is commonly managed with non-steroidal anti-inflammatory drugs (NSAIDs), nutraceuticals, and other medications aimed at alleviating pain and inflammation. Although NSAIDs are generally considered the most effective option, their use is contraindicated in certain conditions due to adverse side effects. Consequently, there has been growing interest in alternative or complementary therapies, such as acupuncture, laser therapy, and their combination. Laser acupuncture involves stimulating traditional acupuncture points with low-intensity laser light, producing anti-inflammatory, analgesic, anti-edematous, and bio-stimulatory effects. In this study, 19 dogs with osteoarthritis were assigned to two groups: 10 received laser acupuncture treatment (Group T) using a dual-wavelength system delivering continuous and pulsed, synchronized emissions, while 9 served as controls (Group C). After 30 days, only Group T showed significant improvement (p <: 0.01), with reduced pain and improved joint mobility. Significant reductions in LDH and CPK were observed in Group T, along with changes in inflammatory markers (IL-6 and IL-10, though not TNF-&alpha:) and a significant increase in biological antioxidant potential. These preliminary findings indicate that laser acupuncture, applied according to a standardized protocol and adapted to the site of disease, may represent a viable non-invasive therapeutic option for canine osteoarthritis, particularly in cases where pharmacological treatment is contraindicated or ineffective. Further large-scale, randomized controlled trials are warranted to confirm these results and establish long-term efficacy.
