Holy cow, Perdue. I said "congratulations" on the trainer you found before seeing your post about who they are. These methods are considered very "old school", as are Koehlers. Koehlers' being considered out right animal abuse by many well respected pros' in the industry. I'm not talking about a pop on a prong collar, but rather dogs being strung up, air supply cut off, damaged trachea, bruised hocks from stick corrections. I've seen extreme abuse in these types of programs. As far as trainers relying strictly on physical punishment to achieve obedience, it's considered the lazy mans way of training. I just want to caution you... look out for your dogs well being. Granted, many of us who are trainers can drop a dog in a second and demand a down-stay, even from an aggressive dog in a group setting. Most of us also know better though and work to achieve a level of training that eliminates the dogs desire to break that stay and go after the dog next him. It can be done without these methods. Be careful about what you allow them to do to your dog in the name of "obedience." I have a client whose Malinois turned on him, after extensive training with a Koehler method school. Another whose dog, while never considering disobeying the male owner who did this method of training with him, then attacked the female owner when she corrected him for stealing food. (Simply grabbing his collar and trying to pull him off the counter.) It took a lot of "rehab" and re-training for one that came to me. The other was put down. Yes, they can guarantee it will change your dogs response and behavior, but not always for the better. What compensation do they offer if your dog happens to be one of the dogs ruined with this type of training? Just a thought.
