The type of closure used depends upon the site on the body, individual animal characteristics, and the presence of other factors that may delay wound healing. During a surgery all three layers (muscle, subcutaneous layer, and skin) need to be closed . Closing the muscle layer is closed with individual stitches that go perpendicular to the incision. The subcutaneous layer is closed with a continuous suture means that multiple stitches are made without tying individual knots for each one. The skin incision can be closed with sutures, staples, or surgical adhesive.
