Urban rat catchers club

A group of dog owners stand in one of the lower Manhattan alleys where they gather to let their various breeds hunt rats in New York, April 26, 2013.

The group, known as the Ryders Alley Trencher-fed Society meet about once a week, weather-permitting, and have been doing so for about a decade.

The dogs hunt best when they work as a pack. After making a kill with a bite or a shake, the hunters trot back, rat in mouth, and allow their owners to take it from their jaws. The night's kill ends up in a trash bin.
