[QUOTE=RedFury]
Having written what I’ve written right before your post, I feel I should be able to back my claims as well. I mean, I know that you are a dog lover like myself – or even more – but surely you can’t be saying all breeds have the same expected temperament (and again, there are obviously exceptions to any rule, added to the fact of the type of training the dog gets – or lack thereof).
So beyond the link I posted above, here’s a few more:

Oooh, you linked to the American Temperament Testing Society site. 
They’ve been systematically evaluating individual dogs with a very detailed formal temperament test and keeping statistics by breed.
I do think they’re some element of self-selection – people apply to have their dogs tested, if I understand. So it’s not a wholesale scientific survey. But it is the most rigorous data set currently available on the temerament of dog breeds, especially dogs whose owners assure you they’re well behaved (the kind who would pay to have that dog tested), so they’re relevant, IMHO.
In their tests, pit bulls and pit bull mixes consistently outscore many, many other breeds of dogs. What follows is a somewhat selective list of the most heavily tested breeds (and a few notable breeds even though those sample sizes are smaller):
AMERICAN PIT BULL TERRIER 84.1%
AMERICAN STAFFORDSHIRE TERRIER 83.9%
AUSTRALIAN SHEPHERD 80.7%
AKITA 73.6%
BEAGLE 79.7% (admittedly a small sample size, included because of reputation)
BORDER COLLIE 80.0%
BLOODHOUND 71.9% (small sample size)
CHIHUAHUA 71.4% (small sample size)
COLLIE 79.2%
DACHSHUND 75.9% (compiled from several categories of dachsund)
DOBERMAN PINSCHER 76.8%
GERMAN SHEPHERD DOG 83.3%
GOLDEN RETRIEVER 83.8%
GREAT DANE 78.9%
LABRADOR RETRIEVER 91.5%
MIXED BREED 85.6%
ROTTWEILER 82.7%
SHETLAND SHEEPDOG 67.3%
STAFFORDSHIRE BULL TERRIER 85.2% (small sample size)
STANDARD POODLE 85.7%
WEIMARANER 79.6%
AVERAGE FOR ALL BREEDS 81.5%
(Compiled by me from the statistics on the ATTS pages.)
The bolded breeds are the three traditionally considered “true pit bulls,” although “mixed” (which also scored well) includes a fair number of pits (pit bull owners often list their dogs as “mixed” on official forms, much like Jews hiding their ancestry in Nazi Germany. This is not a specious comaprison, as the fear in both cases is (was) being rounded up by the government because of one’s “race.”)
Note that, aside from the impressive score racked up by Labradors, pit breeds score as well as or better than almost everything out there and consitently better than some breeds. The pits are also all above the average for all dogs.
