Cafes with outside seating are ideal places to stop for a bite to eat with your dog.
Many places will even provide bowls full of water ... although I’m not a fan of communal water bowls, especially ones that have obviously been sat around for a while. You might want to take your own bowl with you, if it’s a warm day or you’re stopping for a while. Be considerate of other diners and remember that many cafes are small, family-run businesses that will not want to lose customers. Make sure your dog is used to lying quietly under the table while you eat and will not jump at other customers or beg them for food.
