case_images: A 5-year-old intact male mixed breed dog (body weight = 28.0 kg) was presented with two wide dorsal ulcers: the dimension of the thoracolumbar lesion was 10.0 cm x 9.0 cm and the circular lumbosacral lesion a diameter of 15.8 cm (Figure 1(a)). Overlying skin of the affected areas sloughed off, according to history, exposing a crust-coated reddened subcutaneous and deep fascia tissue (Figure 1(a)). After clinical examination and shaving of the dorsal thorax, this area showed crepitating cyanotic patches of necrotizing skin (Figure 1(b)).
