The objectives of wound care are to prepare the wound for surgical closure while minimising the risk of wound infection or to control wound infection thereby promoting wound healing. The aim of any treatment is to return the animal to normal function and cosmetic appearance. The selection of the wound treatments for each particular case involves many interdependent factors. The duration of the injury is important because wounds have a better prognosis the sooner they are sutured or treated. The cause of the injury will influence the prognosis for healing and also the likelihood of infection. Sharp lacerations are generally less prone to infection than shearing wounds caused by barbed wire, bite wounds, or degloving. Previous treatment by the owner, for example the over-enthusiastic use of antiseptics or local antibiotics, may mean that the wound may no longer undergo primary closure by suturing. The location, depth and configuration of the wound; the degree of contamination; the intended use of the animal; and the co-operation of the patient and the owner should also be considered.
