Thanks for the concern. But don't worry, I've already emailed them some questions. I asked them what methods she used to build aggression when attack training, where the trainers were certified, if you are able to bring your own dog, how they train for personal protection/shutzhund etc. I also called a couple references and asked them a few questions, and they assured me that it was a great place with positive training methods only. Ashley's (binka_nugget's) dogs' trainer also says that she learned alot there and Ashley says that she's very knowledgeable and informative.
