Cali went all the way through her obedience cgc and therapy program in her buddy belt. No collar for her. I have been in obedience for years and most teachers are not familiar with toy dogs. A 100 pound dog may need a choke collar at the beginning ( and they can be used humanly) because it may take that to keep them in. On troll and the other dogs safe. Once the bog dogs calm down they do well with regular collars or harnesses. If you show in the AKC ring you must use a collar -I have a small collar that I made for her that does not tighten for that.
Don't be intimidated by the big dog trainers. Just learn what your dogs needs to do and do it with the harness. Your dog is smart enough to learn it all, and they do not need to be man-handled to get it.
