A 9-year-old male Lhasa Apso came into the clinic on March 12, 2007. Another dog had attacked him the previous weekend. Initially he was treated at another vet clinic were his wounds were cleaned and he was started on antibiotics. When the pet first presented to our hospital, the wounds were large black areas where the skin had been traumatized. It was evident that these areas of skin would eventually die and slough away. This leaves an open wound. Bite wounds are contaminated and should be treated as open wounds in order to allow drainage and healing by granulation tissue.
