Getting your dog comfortable in different environments is a big part of responsible pet ownership. One experience that can be especially rewarding—though sometimes a little tricky—is bringing your dog along on public transportation, like a subway or commuter train. Here’s what I’ve learned from riding the train with my dog, and how you can make it a stress-free adventure for you both.

Before hopping on any train, it’s important that your dog is confident with basic obedience commands. “Sit,” “stay,” and “heel” are must-haves for navigating busy platforms and crowded train cars. Use plenty of positive reinforcement and bring treats to reward calm, good behavior.

Public transportation can be noisy, crowded, and overwhelming—especially for dogs who aren’t used to that kind of environment. To ease the transition, gradually expose your pup to similar situations. Visit busy parks, outdoor shopping areas, or local markets to help your dog get used to strange sounds and lots of people.

It also helps to get your dog used to smaller, enclosed spaces. Since trains can get packed, practice staying in small rooms or even elevators together. Use a short leash when on the train to keep your dog close and prevent accidental tangles or bumps into other passengers.

And don’t forget to be courteous to everyone around you. Make sure your dog is clean, well-groomed, and calm before boarding. Bring a portable water bowl, and always have waste bags on hand in case nature calls.

With a little preparation and the right mindset, taking your dog on public transportation—whether it’s the New York City subway, Chicago’s L, or another local train—can be a fun, rewarding experience. It’s a great way to explore the city together and build your dog’s confidence in new environments. Just remember: preparation, patience, and treats go a long way!
