Sex hormone drug exposures in pets draw notice in Europe

The first report to capture Dr. Ann Neubert's attention involved a breeder of French bulldogs and Chihuahuas. Over the course of three months, four puppies were born with curious features. Three females had enlarged vulvas, while one male had swollen mammary glands. The apparent cause: exposure to a medication the breeder put on her skin containing the sex hormone estrogen.
