Remember that lesbian who got torn up in San Francisco by her neighbor's two dogs? One was a Canary Island something or other, which apparently are big and often very mean dogs.
Rottweilers have that rep too.

Some German strains of German shepherds are bred for meanness too, but that's to make them scarier guard dogs, not to fight other dogs. Same with Dobermans, who are often psychologically way out there on the edge.

But I don't know what that city council defined as fighting dogs. I'm sure pit bull is always the first breed whose name comes to mind.
