The granulation tissue formed with the use of amniotic membrane (ME) and canine pericardium (PE) as an occlusive biological dressing in experimental cutaneous wounds was evaluated Fifteen dogs, having three wounds on the dorsal thoracic region of each (FA -amniotic, FC -control and FP-pericardium) were used. Clinical and histological evaluations were carried out, including counting and measuring the average diameter of the blood vessels of the granulation tissue, as well as bacteriological exams (swabs) of the wounds and the grafts. The granulation tissue formed after seven days of using the canine amniotic membrane showed a vascular histological aspect, being able to be favorable to the cutaneous grafting. It was concluded that the use of amniotic membrane and canine pericardium dressing on cutaneous wounds during seven days did not stimulate the presence of granulation necessary for the use of cutaneous grafting, however, it can be used as an occlusive biological graft.
