My 3 year old Mal bites solid, but does not like to OUT. When he does out, he goes into a rear guard and bark. Do you have any suggestions?

Mr. Frawley,

My name is Justin, and I am a K9 security Officer at a hospital in Scottsdale AZ. I have a question about outs, recalls, and a rear guard and bark. My partner is a 3 year old Malinois that was trained in IPO. His bites are very solid, but he does not want to out. When he does out, he will go into a rear guard and bark (for the escort, like he was trained before in Europe.) We had an incident last training night where Robbie got "Dirty" when he was in the guard and bark, he bite the agitator. Do you have any ideas on how to change him from a rear guard and bark to a front guard and bark? Also he does not want to recall after an out, again any suggestions would be great. We have tried a pinch collar, an E-collar, and even an Electric prod. He is a great partner, and we want to stop this quickly so we do not have an incident in the hospital, of an accidental bite. (Just on the side we are NPCA certified, and train with the Scottsdale PD every week. - Just so you know the general background)

Thank you for you time and wealth of knowledge
Justin and Robbie
