Yorkies and other breeds with delicate necks should be allowed to wear the harness! There's a reason why they aren't wearing a collar, so why should they to take a test? After the test, they are free to go back to the harness. I don't think it makes any sense... And why risk the "extreme injury" part? If the dog's neck
isn't hurt, and they make you test with the collar and then they
do get injured, well, that's just not right. And who would be responsible? The owner because they can't stop their dog from choking itself? Or AKC, who won't let the dog test without risking being hurt? I think AKC should be responsible if something were to happen. Especially during the separation part. I wouldn't be there to try to stop Sapphire from choking, but the person in there is told to just hold the end of the leash and let Sapphire do whatever, including choking herself constantly...
