I entered my pitbull terrier (Pedro) into JJ’s 3 week on-boarding training program for his insecurities/lack of impulse control and he ended up staying for about 4 weeks. When I got Pedro back his behavior was drastically better! Car rides are less traumatic, walks are manageable, and I can open the door without him lunging at the person knocking. He still has some impulse to work on, but it is nothing like when he first started. Very kind and very dedicated crew! Would recommend wholeheartedly!
