Plain-English summary
A group of 20 dogs with hip osteoarthritis received either a common pain medication (meloxicam) or treatment with a therapeutic laser (photobiomodulation therapy) over three weeks. The dogs treated with the laser showed significant improvements in pain levels and joint function as early as eight days after starting treatment, with continued benefits observed up to 90 days later. The laser therapy helped increase their range of motion and overall quality of life, making it a promising option for managing osteoarthritis in dogs.

Abstract
OBJECTIVE: To evaluate photobiomodulation therapy in dogs with bilateral hip osteoarthritis. ANIMALS: 20 dogs. PROCEDURES: Forty joints were assigned to a control group (CG; n = 20) or treatment group (photobiomodulation therapy [PBMT]; 20). CG received a 21-day course of meloxicam, and PBMT received treatment with a Class IV therapeutic laser over 3 weeks. Joint range of motion, thigh girth, the Canine Brief Pain Inventory (divided into pain interference score [PIS] and pain severity score [PSS]), Hudson Visual Analogue Scale, Liverpool Osteoarthritis in Dogs, and Canine Orthopedic Index (COI; divided into function, gait, stiffness, and quality of life) were evaluated before treatment, +8, +15, +30, +60, and +90 days after initial treatment. Results were analyzed with repeated measures ANOVA or Wilcoxon signed ranks test, P < 0.05. Kaplan-Meier estimators were compared with the Breslow test. RESULTS: Patients had a mean age of 8.3 ± 1.9 years and body weight of 65.7 ± 12.1lb. Osteoarthritis was classified as moderate (n = 26) and severe (14). No differences were found at time 0. Better results were observed in PBMT at +8 days (P = 0.01 for PSS, P = 0.04 for function and COI), +15 days (P = 0.01 for PSS and function, P = 0.02 for PIS and function, P = 0.03 for COI and P = 0.04 for Liverpool Osteoarthritis in Dogs [LOAD]) and +30 days (P = 0.01 for function and gait, P = 0.02 for COI, and P = 0.04 for PIS, PSS, and LOAD). Joint range of motion improved in PBMT from +15 to 90 days. Kaplan-Meier estimators showed that PBMT produced longer periods with better results. CLINICAL RELEVANCE: PBMT reduced pain levels and improved clinical findings in dogs with hip osteoarthritis.
