Class IV laser therapy has emerged as a promising non-invasive approach to promote tissue repair, but its use in small animal post-surgical wound healing remains underexplored. This preliminary study evaluated the effects of Class IV laser therapy on the healing of surgical wounds in 49 dogs and cats. Each incision was split into two anatomical zones: one treated with laser (CL) and the other left untreated (SL). Wound healing was assessed at three timepoints (T0, T1, T2) using validated clinical parameters. Laser-treated areas exhibited significantly reduced skin thickness, improved vascular coloration, faster hematoma resolution, enhanced elasticity, and decreased fluid accumulation compared to untreated areas. These effects were consistent across species, sex, and age. Class IV laser therapy significantly accelerated the wound healing process in both dogs and cats, offering a valuable adjunct to standard post-surgical care. Further studies are needed to confirm these findings and explore long-term outcomes.
