Pit bulls are legal to own in Miami for the first time since 1989

Why it matters: Breed bans are inhumane and force dogs out of their homes and into overburdened county shelters, according to the Humane Society of the United States.

• There is no evidence that these bans reduce dog attacks, per the Humane Society.
• Critics have argued that pit bulls are inherently more dangerous than other dogs.

Flashback: The county law was prompted by a 1989 pit bull attack on a 7-year-old girl, who needed more than eight reconstructive surgeries.

• A 1990 state law prohibiting breed-specific dog bans grandfathered in any laws placed before then, keeping the local ordinance enacted.
• In 2012, Miami-Dade residents voted to keep the ban in place.

Details: Under the ban, the county could fine pit bull owners $500, seize their dog and euthanize it.

• The ordinance specifically prohibited American Staffordshire terriers, Staffordshire bull terriers and American pit bull terriers — or dogs that "substantially conform to the standards" of those breeds.

Zoom in: The repeal of Miami-Dade's ban could bring relief to shelter overcrowding in neighboring Broward County, where dog owners say they are afraid to surrender certain breeds due to the restriction.

• Miami-Dade is facing its own overpopulation issues at its main animal shelter in Doral, forcing it to house some animals at a secondary shelter with no air conditioning.
