I don't really like either.

There was an obedience class that I was going to take Jasper to, and it was a rule that they had to wear chokers. So I took him to a clicker training class instead.

I would never use either unless *every* other method/option didn't work-even with help of professionals. However, I'm not sure if I would even use one then.

I prefer to use positive reinforcement, and Jasper learns very fast when I'm telling him what he's doing right(and not wrong)
