Judge has a beautiful out on a sleeve or toy, a bit possessive but a nice out.
That said.....
When we had the home invasion and he got a live bite, he was choked off, for one, I couldn't have remembered how to out him if I had wanted too(adrenaline, fear etc.) for 2...he just wasn't letting go. He did let loose to regrip but he re gripped and held and shook. He has been trained to bite and hold, that is exactly what he did. A real life scenario with adrenaline and fear etc. is a whole different ball of wax than playing a sport on a sport field with toys. IMHO- just because a dog has to be choked off a bite in a certain scenario doesn't make them unsafe. Let me tell you, I have a new appreciation for the K9s and their handlers. I will tell you, in the situation me and my dog were in, I did not want him letting go, I imagine it is the same in their situations most of the time.
I've had working dogs redirect on me in certain situations, my own dog included. A little redirect doesn't mean the dog is unsafe or unstable IMHO.
FWIW- In my area, most of the K9s are Dual Purpose and all are VERY stable dogs. Well controlled and some even semi social.
