I would still be careful. My trainer doesn't allow choke collars even if someone wanted to use one. If they want you to do leash corrections I would run the other way. It can make problems worse and it's painful for your dog.
I really hope all goes well. We liked our first class so much we did about 5 more!!! Canine Good Citizen was the most fun. Training classes are a good way to spend time with your dog and have him totally focused you and and on learning new things!
