Estelle Stamm, 65, who won $10,000 in a lawsuit against the city after two police officers gave her a citation for bringing her dog into a subway station, claims in her federal suit against NYC Transit that the livestock guardian dog is a service animal that helps with her post-traumatic stress disorder stemming from childhood sex abuse, the New York Daily News reported Monday.

The suit claims Stamm's civil rights were violated by transit workers who confronted her about the dog. However, the transit authority claims there were no violations as Stamm and her dog were never removed from any buses or trains.

Stamm's suit is seeking $10 million in monetary damages and employee retraining for transit workers.
