Being a city dog isn’t hard – if you’ve got style.
My human has been wearing a cap his whole life. Not because of a bad haircut – he hasn't had one in years. He wears it as a flag. A warning sign to everyone around:

"I don't like small talk. Especially not while dog walking."
And trust me, nothing ruins his day like a stranger striking up a conversation by the trash bin while he's holding my poop in a bag and hearing, "We used to have a dog too… but then he died, and since then…"
We're not antisocial. Just… selectively social. And the cap helps. It's like an "invisible umbrella" shielding us from questions like: Is he friendly? Can I pet him? Is that a poodle?
Now we've got a new cap from Collar of Sweden, and it says: "Anti social dog owner." It has style, just like me. It matches my new blue collar and looks so good, my human would've bought it even if he didn't have a dog. Same with their tees and sweatshirts.
They're not your usual pet shop stuff – the ones that look like they were designed half-asleep. No. This is design that gets it: Being a city dog (and his human) is an identity. Not a job.
And when someone asks if the slogan is a bit rude, I just say: "No, you're just too curious."
Being a city dog isn't hard – if you've got style.
