This painful condition usually attacks bitches while nursing their puppies, the abscesses that are liable to form at other times being generally of slower growth and not accompanied by systemic disturbance. The milk gland in acute cases is swollen, hard and red and very painful, and the elevation of temperature indicates the formation of pus. After two or three days the swelling becomes softer, comes to a point, breaks and freely discharges. If the bitch is nursing it is necessary usually to remove the puppies and feed them by hand or turn them over to a foster-mother, the mother meanwhile being milked two or three times a day. The swellings should be poulticed with flaxseed until they are soft, and then lanced. As a rule they do not require any other treatment, for their dependent position insures free drainage. It is advisable to keep the patient's bowels open with a dose of aperient medicine.
