Earlier this week, a dog attacked two people in Minot.
According to a Minot city ordinance, the Pit Bull responsible is illegal to own.
Fargo doesn't have any breed bans, but the city does have an ordinance that your pet needs to be registered every year.
"If they're spayed or neutered it's $2.50, if they're not spayed or neutered it's $5.00," says Fargo Community Service Officer Sara Fix.
That tag helps keep track of vaccinations if they get loose and the small cost is better than if you're caught without it.
"It's a $50 infraction and it's a must appear in front of a judge," says Fix.
An unprovoked attack to a human or another pet is reported to the city prosecutor and then a judge.
"The judge is the one who determines what level...if it is going to be deemed as 'potentially dangerous' or a 'dangerous' dog," she says.
"Potentially dangerous" dogs can have the offence removed by graduating from obedience classes, but Fix says there aren't a whole lot of "dangerous dogs" out there. That's because she says many owners can't afford the registration cost per year...and those offenses can't be removed.
"It's a $500 registration fee, it's a $300,000 liability insurance that they have to cover on the animal. Must be microchipped, must be spayed or neutered," she says.
The Fargo-Moorhead Humane Society sees dogs of all shapes, sizes and breeds.
"There are no breeds out there that are inherently more dangerous than any other breed," says Shelter Manager Heather Clyde.
They say it's all about how a dog is raised and trained.
"It's just whether or not they've been properly socialized and of course if they've ever been abused or anything like that in the past or if their owner has trained them to be aggressive or territorial," she says.
Fargo Police say if you're concerned about if a dangerous dog lives in your neighborhood, give them a call.
