If you are still reading Coley, do take heed, the site is glib crap, no decent trainer would even have a 5 month old pup started in anything other than obedience, nor could they yet know if it will have the nerve and temperament to be a stable protection dog as an adult, nor would they tell you that in one day you can learn to handle a protection trained dog, absolute bull XXXX.
I have done quite a lot of protection and obedience training with my own dogs and never ever would I send a dog away, you need to learn just as much as the dog does, more in fact.
It is like riding a bike, looks easy, but it take skills which you need to learn too, you also need an extremely stable dog and you need to see it trained and make sure it is not 'table' trained as others have told you.
Learn a lot more before you commit to a trained dog, many dogs will protect naturally and all you need do is obedience.
I doubt Cesar knows their reputation or he would not have been seen near them, he did have Daddy protection trained, but would not use methods even I who live hundreds of Ks away have heard they do use.
Anyway, he trains people, not dogs, he only rehabilitates dogs, different thing altogether 8>)
