If your dog is small, well-behaved, and you’re traveling outside peak hours, go for it. You’ll be the highlight of everyone’s commute. But if your dog is a hyperactive, slobbering, leg-humping machine? Take the bus. Or walk. Seriously, walk. London is lovely above ground, and your dog will thank you for not forcing him into a metal tube full of strangers who smell like rain and regret.
And if you absolutely must take the Tube, remember this golden rule: you are not the main character. Your dog is. Accept your role as the humble human who carries the poop bags. That’s the price of being a London dog owner—and honestly, it’s still a better deal than renting a flat with a garden.
