I just brought my 2 dogs to Lorenzo's today for an evaluation and to determine what my best options were. The trainers that I spoke with seemed very friendly at first. One of them was newer and somewhat seemed to be in training himself. I was immediately concerned when their first move was to bring out choke chains (called correction collars by some). What they did to my dogs was sickening. They used full strength to jerk and choke my dog to get him to walk with them, and my dogs were shaking in fear. They had a demo of what the expected results were to be. The dog that was used in the demo (and had been fully trained by them) was fearful and shaking. There was not a single tail wagging in there.
I made a point to ask if dogs were even happy once they go through training with them, and of course they said yes. I truly believe the answer is no. I got in my car and cried because I was horrified by what just happened and what I saw.
So go to Lorenzo's if you want your dog to be extremely obedient and also extremely afraid of you. All of the dogs looked like they had their spirits crushed. I could see these methods of training winding up causing aggression. I will obviously not proceed with training here.
