They wore shirts that read, "Pit bulls are not the problem, bad owners are the problem," and held signs that said, "No BSL."

BSL stands for "breed specific legislation." The protesters of Miami-Dade County's more than 20-year ban on the breed call BSL "canine profiling".

Dahlia Canes told Local 10 she started the "Miami Coalition Against Breed Specific Legislation" seven years ago.

During Sunday's rally outside Tropical Park supporters asked passing cars to honk if they support their cause. Their goal is to support lawmakers on a state level who are working to end Miami-Dade County's ban.

Bills are currently making their way through House and Senate committees.

Canes said if Miami-Dade County's ban is lifted it could save taxpayers millions of dollars each year and set precedent for smaller cities and counties nationwide to do the same.

Canes dismissed critics who argue Pit bulls are more likely to bite someone than a Maltese, for instance.

Miami-Dade County Animal Services told Local 10 that Pit bull enforcement is complaint-driven.

A USA Today article from 2010 found that despite the ban being in place for more than two decades, there was no solid evidence to show how effective it had been in preventing dog bites.

The Centers for Disease Control and Prevention looked at data collected from the Humane Society and media reports from 1979-1998 that involved dog bite-related fatalities or DBRF. Here's what they found:

"Most victims were children. Studies indicate that Pit bull-type dogs were involved in approximately a third of human DBRF reported during the 12-year period from 1981 through 1992, and Rottweilers were responsible for about half of human DBRF reported during the 4 years from 1993 through 1996. These data have caused some individuals to infer that certain breeds of dogs are more likely to bite than others and should, therefore, be banned or regulated more stringently."

The study goes on to say that drafting an effective breed-specific ban is problematic, in part because the dog breeds that have resulted in deadly dog bites have varied over time.

"Breed-specific legislation does not address the fact that a dog of any breed can become dangerous when bred or trained to be aggressive," researchers said.
