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.” – Dr. Kristopher Irizarry Download and read the full report
