If I had to choose, it'd be Victoria. I use a lot of positive reinforcement training with my own dogs, so of course she'd be my choice. She certainly couldn't do any harm to my dogs, IMO. And to be honest, I don't feel that Cesar could do any harm to my dogs either (can't really imagine him doing anything detrimental or extreme to my dogs considering they don't have any behavioural concerns that would warrant anything extreme like you generally see on his show). But his methods are methods that I prefer not be used on my dogs regardless.
With that said though, I really don't care for any of the TV trainers and would not take my dogs to any of them. The main two (Cesar and Victoria) both seem like nice enough people when not training dogs, but as far as actual training and behaviour management goes, I feel that there is much better talent and knowledge right here in my own city.
And since he was brought up: I wouldn't go near Brad Pattison for anything. A co-worker of my mom's daughter went to one of his seminars (free ticket) and the things he did and the stuff she heard and witnessed in real life were just disgusting. Perhaps moreso than what is shown on TV. She didn't stay to finish. He was obnoxious, rude, belittling, and his training philosophies were nuts. I know a few people who trained under him and with him as well, and the one person inparticular can't stand him and has since learned much better methods.
