goldens are a great breed, but not one to get into protection work...Its just not in them. You may be able to teach them to bark, but you wont be able to count on them for that. I started training dogs with service dogs for disabled vets. I.E. turn on/off lights, open fridge, seizure response dogs, and such. I now train mainly Shutzhund, Personal Protection, and Basic Obedience. (need to do obedience to make a living.)
My point being, GRs were GREAT for service work, because of there soft, open nature towards most humans, and their almsot NEED to please.
Believe it or not, I am a FIRM believer in APBT. I have one, he is shutzhund trained, and plays with 2 year olds all the time. My father in law even lets his kids play with Manson. Pits are VERY loyal, and protective by nature.
Im stoned, thats why I am jumping all around. Bear with me.:jointsmile:
You will DEFINITELY want a professional trainer regardless. There is a very fine line between teaching a dog to protect, and teaching a dog to attack. Not a chance I would recommend taking.
Have any questions, post em, Im subscribed:thumbsup:

shutzhund is what you wanna look into if you want a protective dog that you can still have as a family pet. Personal Protection dogs, not so much....
