IMO, it's not bad, but as with any sort of standard 40-question assessment ~ whether for dogs, people or any other animal ~ it tends to be lacking quite a bit.
As for drives, there's a fair amount of debate in the first place as to whether or not pack, fight and flight are really drives and prey drive is quite complex.
Are you sure those aren't supposed to be 4.0, 6.5, 2.5, and 5? I thought they rated on a scale of like 0-6 or maybe even 0-10??? IDK.......I might be thinking of a WHOLE other thing, LOL
EDIT: I see corgi's post...........so never mind! LOL, thanks Corgi, very interesting
