What is a temperament examination?
Please write a letter to U.S. Attorney Michael Gill urging him to allow all dogs who pass temperament evaluations to be taken by qualified rescue organizations
Is it something specific to the pit bull? Is it conducted by an expert? I would hate for a dog to be deemed unrescueable and put down, or for a dog found rescueable to be involved later in an accident with a person.

Can you re-train a pit bull (or any aggressive dog, really) to learn to get along with people? Look at retired racing greyhounds, they really have no experience with being part of a family until they go through an adoption program. Once they retire, they have to learn everything about living in a home and being a pet. Those folks must have expertise with identifying the few who can't successfully adapt to a life after racing, but it seems like the great majority of greyhound "retirees" do just fine.
