Dog Training Services in Columbus Ohio What type of training methods do we use for obedience and off leash control with dog? As a Columbus Ohio Dog Trainer, we will never punish a dog for doing something that is undesired because that ruins trust and does the opposite of forming a strong bond between the owner and their dog while your K9 is learning different obedience commands. We will never condone yelling, punishing or intimidating your K-9 to get your dog to do what you want.
