Should the dominant dog color be a bit bigger if you use it as a safety with the prong?

Hello Cindy:

Thank you very much for your answers to my e-mails in the past.

It always helps. My GSD pupp Emma is 6 months old today; doing great!!

I have a question about sizing the dominant dog collar if you are going to use it as a safety with the prong collar. I follow your advise on how to properly use and size these collars; however, should the dominant dog collar be a bit bigger if you use it as a safety with prong?

I am a bit confused. I want my prong to be the function and have the dominant dog collar only as a back up in case the prong brakes. I am wandering if the dog would not get "two" corrections if the dominant dog collar is basically the same size as the prong.

Thank you again for your help and looking forward for your feedback.

Best Regards,
Robert

PS: The last time I asked you about correcting my puppy for eating my turkey sandwich. Thank you for "waking me up"; I was ahead of myself in the training.
