They don't put you in jail for not registering your dog; it's just such a bogus argument. We register cars, okay? What impact has the registration of cars had on impaired driving? Zero. Licensing? Sure. You can take away somebody's licence, but you don't take away their car registration. If somebody's car registration expires, do people come to the house and take the car out of the driveway because its registration has expired? I don't think so. I've never seen anyone who had a driver's licence plate expire and had his car seized because that happened.
