Photo by myself on the Q Train, around Canal Street.
The woman standing in front of me graciously allowed me to take a photo of her beautiful dog, a Pomeranian mix.
The dog was calm throughout the whole train ride, his head poking out of a dog carrier. The carrier looks like a tote bag but is specially designed with a scoop taken out of the end panel.
Dogs and other animals are allowed on the subways when transported in carriers. Seeing-eye dogs are also allowed, on leashes. To transport a bigger dog, you will need to take a cab.
