Case Study: the Financial Cost of BSL
Breed-specific legislation is costly. Millions of taxpayer dollars are wasted on enforcing ineffective laws. Prince George’s County’s BSL has been in place since 1996. In 2001, it cost the county $560,000.

Read statements from organizations and businesses on how breed-specific legislation is anti-science, damages the relationship between dogs and people, and doesn’t prove to keep communities safe.
You can share these statements with law and policymakers to show them how many reputable organizations do not endorse BSL.

Breeds and Behavior
Peer-reviewed research on why looks don’t equal behavior and dog bite hysteria is unfounded
Nicholas Criscuolo v. Grant County
“Regardless of whether someone inaccurately believes that a specific breed has a certain behavior or “dangerousness,” a dog with moderate or minor/trace amounts of that breed has the majority of its genome derived from breeds other than the breed in question. It is not rational or scientifically valid to assume that a dog can be defined as dangerous by virtue of having “any element” of a particular breed.”
