If you are talking about the temperament test. Balto was near perfect.
Afterwards, the main judge told me the only place he lost points was for not looking into the noisy bucket. He was too interested in the person hiding behind the blind who dropped the bucket. Another of the judges came up and whispered to me that he had never (before Balto) seen the (main) judge give a dog a 10 in the agression test. Lots of 9s, but never a 10.
My Malinois has a noise issue. She was fine as a puppy and loved storms, but get got worse. So, the gunfire was an issue for her and she would have failed as soon as we got to that part of the test. I used the day as an opportunity for her to be exposed to all the different sounds. If I would be able to skip the gunfire I think she would have done okay and probably passed. So, maybe another time for her.
The other two Belgians were not there for the test, but belonged to workers. The test was given by a chapter of the American Belgian Tervuren Club to benefit their National Specialty.
A lot of dogs showed up and most passed. I saw one that totally freaked out during the gunfire. And there was a sweet bully-type dog that knocked down her owner trying to get away from the agressive stranger. But, like I said, most passed. Also, most were bully breeds or mixes.
The aggressive stranger test was the most interesting, though. The dogs are judged according to what is expected from that particular breed-type. The Malamute took one step forward and barked. After the stranger left it gave another bark as if to say, "that's right, get out of here".
I was told that an expected response for many breeds is to move into a position between the aggressive man and the handler in a protective stance.
