I've done them with every dog I've every owned since the late 1980s. I love it! I think it's a good judge of basic temperament for many breeds. For some with unique temperaments, it might not be the best indicator, but you have three evaluators and they don't expect all breeds to respond the same - they take the breed's expected temperament into consideration when scoring a dog (i.e. the Chihuahua or Poodle isn't expected to show the same protection instinct as a Rottweiler or GSD).
