My dog definitely disagrees with that. She would prefer if no one outside of our house existed or at least never walked anywhere within about a 3 house radius because that’s obviously intended to be disrespectful to her. We’ve tried to train her to stop, but she’s a very vocal breed and we kind of knew what we were getting into.
Mine’s about 14lbs, so delivery people usually just laugh at her. I always pick her up or otherwise restrain her before opening the door, though. Regardless of size, it wouldn’t be cute if she bit someone’s ankle.
