Don’t worry, you can still have a giant, slobbery friend without breaking the law. Labradors, Golden Retrievers, and even Great Danes are totally legal. Honestly, Great Danes are like small horses, but nobody bans them because they’re too busy being clumsy, lovable derps.
You can also get a Border Collie (if you enjoy being outsmarted by a dog) or a Pug (if you enjoy constant snorting sounds). The UK is a paradise for non-banned dogs—just avoid the four listed above, and you’re golden.
