A valuable two year old English Setter bitch had whelped nine pups three days previously. Following parturition there had been a constant hemorrhagic vaginal discharge with resultant weakness. Her pulse rate was 120 respirations, 48; temperature, 101.8; general condition, good. The mucous membranes were pale and slightly cyanotic. The milk had evidently not agreed with the pups as six of the nine were dead when the bitch entered the clinic and a seventh died in the clinic.
