Can you find the actual test some where on line? Or ask your trainer?
In case our CGN is identical, #8 for us was the same as #1 but the person had a dog with them. The dog had already passed his CGN. We walked toward each other, met, dogs sat, we shook hands and said hello, then we went on our way. Because both dogs were heeling on the left when we met the dogs were separated by us.
#2 was a very brief pet on the head. Not at all like the kind of smoochie pets and full body hugs some people, kids, really want to give your dog when you meet them.
