Your city’s animal control department is understaffed. Those dogs that you see wandering the street have not been investigated, nor have they been certified as nondangerous. Animal control departments are not picking up the loose dogs, the ones that could be dangerous, the fighting dogs that have been thrown out of cars. Unless you address this with your city government, and demand action, you and your children and your grandchildren are in danger from these dogs.
This is graphically illustrated by an article in the Seattle Times entitled “Pit Bulls on the loose? You may be on your own.” But do not think that Seattle is the only place that has this problem. Your city has it also.
