Subways, undergrounds, railways, and metros transport millions of people across the United States every day. Many of these mass transit systems welcome four-legged travelers to ride with their human companions. However, rules vary from city to city, so be sure to check out this roundup of the largest and most popular networks in the U.S. before you buy a ticket.
Even if your pooch is allowed to ride on mass transit, it doesn’t mean he should dive right into a rush-hour commute. Start by getting your dog used to his carrier at home, and be sure to reward him when he spends time inside without causing a fuss. Then, begin your public transport adventure with shorter journeys during non-peak hours to get him used to his new surroundings. If your dog doesn’t like loud noises and is easily spooked, a pet-friendly rideshare might be a safer way to get around a city.
