My dad has just told me on the phone that all "dangerous breed" dogs should be wearing muzzles in public because it's the law. He reckons dogs such as my gsd pup and Rottweilers are included in this designation (conveniently forgetting his own rottie/shepherd cross who never saw a muzzle in her life). I've googled but can't find anything. Is he talking out of his arse? He usually does. Surely my vet or dog trainer would've told me this, if it was true?
