Some trainers are okay with using punishment because it often works faster, but it’s hard on the dog. They come out looking like stars at the dog’s emotional or physical expense. My personal opinion is that positive punishment is animal abuse. If you read my answer to which training program is best than you know I tried positive punishment. I’ll always carry that guilt, but at least I know I’ll never recommend it to a client. I recommend finding a trainer that is a Certified Professional Dog Trainer (CPDT) or working towards their certification. Just to sit for the CPDT exam requires 300 hours of hands on training. CPDTs are primarily focused on positive reinforcement.
