I agree with working rott and others. One cannot allow a PP dog to guess.
In my view, ONE of the major difference between a "sport protection dog" and a "personal protection dog" is that a personal protection dog DOES NOT ENGAGE ON ITS OWN. NEVER. Some will argue about this point, but those that do don't train real personal protection dog for the real world. Ask ANY lawyer. And if you don't think a lawyer will not be involved in this decision process, think again. There are many aspects of "work" the dog must do RELIABLY and predictably.
Some may argue about home invasion. Should the dog not guard on its own? What if your family member is crawling into the window late at night, in the dark or comes into the back yard? Do you want your trained dog to react on its own? Probably not. Most clients do not fully understand the ramification of their request and it is up to the responsible trainer to educate the client and match the dog with the client.
You STILL want control.
Now, some may confuse a sentry dog (junk yard dog) with a PP dog. There is a HUGE difference.
YOu see, the dog WANTS to bite. Training the dog, with the right temperment, is training it WHEN NOT TO BITE AND WHEN IT IS APPROPRIATE WHEN IT COMPLIES WITH THE HANDLER'S COMMAND.
A dog is not a mind reader and if you expect it to be, you are in for a rude and expensive awakening.
