. Long before you train a dog to hold or 'bite', you will have a 100% leave in place if you are doing it properly and it will always be a game. When people only train the flashy guardy bits but miss out the basic obedience training it gets dangerous. My best dog, who I would have loved to work in schutzhund/IPO or similar was the steadiest, best natured, as safe as any dog could ever be who would have loved the training but sadly, his legs weren't good enough. He was the only one of my 11 (to date) rotts that I would even have contemplated training to that level. All except one of the others were

I'm not saying you are, but in case anyone reading conflates the two issues (personal protection and sport/breeding assessments) in Schutzhund/was IPO now IP/IGP you can't go forward to do any of it unless the dog has passed the BH (traffic safe companion dog test).
The dog must be able to be scanned for a microchip/walk through a group of people and touched by the judge before it can start the trial.
If the dog DQs in obedience, it cannot proceed to protection. If it DQs in protection for lack of control, all points are lost for tracking and obedience. In fact if it DQs in any phase.
If the dog doesn't react after three commands (recall, let go of dumbbell, let go of sleeve etc) it's DQ.
At big competitions the dog must undergo a rigorous vet check.
They **cannot** be aggressive to humans and in obedience two dogs report in together and one works while the other stays in a down. So no dog aggression either.
The dog can be DQd at any time before it gets it's workbook back.
When I assess dogs I do pretty much the second part of the BH or condensed ZAP WT character evaluation (which has more environmental elements) with no heeling pattern/down stay.
