I think partially due to Nero's floppy ears I haven't had any issues with him on walks (beyond some jerk terrifying him by almost hitting us on a bicycle) or in stores. However bully breeds are common here, despite a ban on pit bulls, as are rotties. I haven't had anyone say anything about his prong collar either, and if they did I don't care. Even my husband has totally come around to the prong and he was very against it. A pleasant walk where the dog can correct himself vs yanking on him all the time? Yeah that's ideal! But I understand how ignorant people can be. Don't be afraid to stand up for yourself and don't let words like this hurt you. They're not true. It's just some jerk who probably owns a chihuahua or a shih tzu.
