This book has saved me countless hours in training my Pitbull mix, she was a recue and an assumed breeder for a dog fighting ring. She's had awful trust issues especially with men and this book has really helped me to develop strategies to regain control and build her trust with me. I'm not sure if i'm allowed to post links here but this is a really good deal for about $50 is what i paid. The website looks awful imo but this one isn't much better, let's be honest

if anybody has any other recommendations, they are greatly appreciated, she's made amazing progress but she's still not fully there, she's finally playing with us but flinches when you reach to grab the toy
