I've read thru that test and seen that test, and it's a good way to get really, really basic info on a dog, but it's so damn general it makes me crazy.
No matter what Sue Sternberg says, as quoted in this test, "a person sitting in a chair" may not stimulate a dog in any way if said dog hasn't been out of a shelter kennel in weeks. In addition, dogs that run up to you and nudge you and pester you for attention and stuff can actually prove to be somewhat dominant . . . I guess it's good that people should have a very general guide for things to look for, but I'm always wary of these tests.
