Background:  :  :  : Animals with extensive cutaneous lesions remain hospitalized for long periods. In addition to increasing treatment costs, this also causes stress in these animals. Low-power laser is widely used to support tissue repair processes. Its use in the treatment of cutaneous wounds has been studied, as it reduces the wound healing period and the consequences caused by the lesion. The study aimed to evaluat the wound healing process of experimental cutaneous wounds in rabbits with the use of laser therapy. Materials, Methods & Results: Ten healthy New Zealand rabbits were used in the study, which were divided in two groups (n=5). Skin biopsies were carried out on day 16 in Group 1 and on day 8 in Group 2. The animals were under general anesthesia for the experimental cutaneous lesion to be carried out. Two 1cm2 wounds were made on the back of each animal. The lesions were measured by a pachymeter in the immediate postoperative period, then covered with sterile gauze and maintained with rubber bandages. The animals were treated only with Tramadon 3 twice a day, during 3 days. Only the lesions on the right side of the animals were irradiated regularly, on each side of the wound, at a distance of 0.5 cm from the margin. The equipment used was a 660nm wavelength AlGaInP laser diode (Laserpulse, Ibramed), pulsed at a frequency of 20 Hz, at a dose of 3J and s
