This involves a case where owners challenge validity of euthanasia order for "dangerous" dog. "Boo," a bullmastiff (large breed of dog), knocked down a child who had walked into his (the dog's) yard. The child accused dog of biting him. The Orange County Animal Control Department ordered that Boo be euthanized as a "vicious" and "dangerous" animal. The owners filed a Writ of Mandamus to delay the killing of the dog until their challenge could be heard in court.
