I just started a control unleashed class tonight w/ Onyx, who has fear aggression issues. I read the book about 6 mos ago(need to refresh) and am excited to go thru the class. I started off tonight going to a CGC class, stayed for the CU to observe and decided we needed the CU class first. Onyx was very well behaved, but we had already been thru a class for an hour before this, so next week we'll see! What I loved about it is the touch time, and relaxation massage as the class begins, puts the dogs in a different state of mind.
