This is where the rules get a little more flexible. Guide dogs and assistance dogs are always welcome, with no extra fuss. They have a job to do, and the Tube is their office. If you see one, give them space—no petting while they’re working.
For emotional support animals, TfL treats them like pets. That means the same rules apply: lead on, carry at escalators, and no sprawling on seats. Your chihuahua can’t claim a seat just because he’s having a bad day. It’s fair, and it keeps the system working.
But honestly, most commuters love seeing a well-behaved dog. A wagging tail can turn a grumpy morning into a “Aww, look at that face!” moment. You’re not just traveling—you’re spreading tiny dog-shaped joy.
Little stories that prove it works
Last week, my friend’s beagle, Daisy, rode the Circle line for the first time. She sat quietly under the seat, staring at everyone’s shoes. A man in a suit whispered, “That’s the best thing I’ve seen today.” Daisy didn’t bark or beg. She just was—a perfect little co-pilot.

Then there’s the legendary Tube dog named Milo, who takes the Northern line to visit his owner’s office every Tuesday. He knows the stop by smell. He doesn’t even need a lead now—he just trots in, plops down, and waits. That’s the dream, right?
But Milo’s owner started with strict training: short trips, lots of praise, and always on a lead. It took patience. Now Milo is a local celebrity, and no one has ever complained. Proof that good behavior makes the Tube a better place for everyone.
