Regarding the obedience, it varies from judge to judge. I've had some judges do group heeling on leash of all the dogs together and that's all there is. I had another judge that wanted almost an entire BH routine! I've had other judges want to see a jump and retrieve (if the dog knows it). Years ago, the judge wanted all the dogs to do a meter jump. My son's Flat-coated Retriever hadn't been taught to jump and we literally taught her that day, starting with a few boards, then gradually raising it up to a full meter, which she climbed. I've never seen that since, however. I've even seen some judges skip the obedience entirely, saying he'd seen enough during the AD. I should say that it had poured rain the entire AD that time, so everyone was pretty miserable by the time it ended, including the judge.
