No, most dogs have a chip. It is not yet a law, but they are working on it. Most breeders chip the pups at the age of 6 weeks. The chipnumber then gets registred to the owners name.
So when you apply for this exam, you have to give the chipnumber, so the exam gets linked to that number.
If you want to compete or take exams with the FHN(federation of dogsports in holland) you have to have your dog chipped. They don't accept any other form of identification, like some old dogs still have a tattoo number in their ear, but they don't accept this any more.
Well, the test is pretty easy for the average dog. It is mostly everyday stuff, that any dog needs to be able to handle in every day life.
But for the agressive or fearfull dog, it can be a tough one.
I failed the first time I did the exam with Cooper, as he had a run in with another not so friendly dog. He lunged at this dog, that had been challenging him all day. And we were send off the field immidiately. Lunging is an absolute NO NO in this test.
The other dog wasn't so obvious in his aggression, so he was allowed to continue, as the examiner had not seen what caused Cooper to lunge.
Fortunately for us, my instructor did see it and she had a word with the examinor, so they failed the test also.
This guy was really getting on my nerves, as he had been following me around even when his dog growled at Cooper. His dog was constantly staring at Cooper, so I kept moving away from them to create distance. But the owner didn't notice this AT ALL

So when we had to do the group test, where you have to do some heelwork with a group and passing each other, Cooper was all fired up. I managed to steer clear of the dog and his owner for a while, but suddenly he popped up in front of me, coming straight at me. And thats when Cooper lunged...
Second time we passed, but only because my instructor managed to get me into the group with only female dogs(of which some were in heat, that's why they were in a separate group

) And being the charmer he is, we had no problems there and we passed

Little cheating

Of course this was well before Cooper's behaviour got really bad. I think he was about two years old then. His behaviour wasn't all that bad, back then.
