If you bring your pet on the NYC Transit System, you need to "hold" your pet. They are strict with this rule and you will get reprimanded if you don't. Having no car nor desire to pay for a taxi, I had to simply grab my pooch and hope for the best at the subway. As it turns out, dogs can be brought onto the subway IF THEY ARE HELD. I saw a woman being reprimanded by a MTA guard for not holding her dog. This is very important, since NYC subway is the best way to get around from park to park.
