Why do Greyhounds have to wear muzzles?
Most people see pictures of Greyhounds wearing muzzles while they are racing. This is necessary to provide protection to them and other Greyhounds while racing. Greyhounds can be very competitive while racing. This deters any snapping, nipping, or biting during a race. Even after adoption, if you have more than one Greyhound running together, it is best to let them run under muzzle to deter any altercations.
