22 of the Cutest Dogs in Bags Riding NYC Trains

"No person may bring any animal on or into any conveyance or facility unless enclosed in a container," decreed the Metropolitan Transportation Authority (MTA), the agency that operates New York City's assorted train lines, several years back.

But New Yorkers — and their pups — are nothing if not resilient and a more than a little creative.

Which, in a "challenge accepted" sort of fashion, has led to dogs being spotted riding the Big Apple's rails in all manner of totes, backpacks, purses, satchels, sacks, briefcases, and the like.

And naturally enough, where there's an urban phenomenon, there's an Instagram account there to document it. Enter Dogs In Bags, which has been chronicling these subterranean canines for the better part of the last three years ...
