Incidence of pyometra observed in our colony-raised beagle dogs over a 12-year period is described. Pyometra was observed in 25 female dogs of more than 4 years old, frequently at 8-11 years, with the average age of onset 9.36 ± 0.38 years. The incidence of the disease was 15.2% of the female dogs (n=165) more than 4 years old. Clinical findings useful in the diagnosis of this disease included an excretion of pus from the cervix, rapid increase in leukocyte count, and enlarged uterus as revealed by radiography. The relationships of delivery, estrus cycles to this disease are discussed. Ovariohysterectomy or uterectomy was the only effective method of treatment. In conclusion, the results indicated that pyometra might be an age-related disease because it occurred particularly in aged dogs.
