Tools For Elektrik Punishment/Corrections Without The Use Of Tools?

Punishment/Corrections without the use of tools? - tools for elektrik

A question about the formation of the previous correction to think about me.
Most coaches use the correction here say things like prong collars, collars Collars Buckle Electric, etc., but that these collars are illegal or not someone lives their faith in "tools" of dog training, but we think the dog is always a correction .

How could you correct the dog without such tools?

Thank you in advance for any answer, I am curious what answers you get. :)
