For pet-loving New Yorkers, the longstanding rules, as set by the Metropolitan Transit Authority overseeing the city's subways, are very clear:
"[N]o person may bring any animal on or into any conveyance or facility unless enclosed in a container and carried in a manner which would not annoy other passengers."
That means that if you own a dog who is not a service dog under the MTA's definition, you can't bring your lovable, furry, floppy-eared pooch on any public transit under the ban. Because most (all?) MTA rules are meant to be bent, broken, and otherwise fucked with -- as every New Yorker knows -- this means that we've all been fortunate enough to capture a host of dogs bagged up in goofy, eccentric, or otherwise adorably interesting ways under the streets of New York City.
