I'm a dog lover, and schutzhund competitor. I am around dogs with working drives everyday. I STRONGLY discourage "jumping" in on one of these dogs. Before you get any dog that still has this level of "pack drive" you need to understand "prey drive", "defense drive", and "fight drive". My fear is that this dog is still basically wild (it is ALL about responsible breeding programs that span decades, and that is missing for this breed to be a companion dog), and without proper training will not know the difference between a rabbit running through a field and a kid getting stung by a bee. Even with training, you still may never overcome instinct.
I often hear people say "My dog would protect my old lady if i wasn't home, he would bite the hell out of a burglar with a weapon!" i say "Great! Would he bite the shit out of your sons 16 year old friend who came running in the house for supper carrying a baseball bat?" Until you are ready to train, trial, test and proof a dog, stick with the animal shelter. Alot of great, loyal dogs there that will bark if someone is outside. That is all you really want- an audible alarm that will discourage the bad guy, and buy you enough time to prepare and have the old lady call 911.
For anybody buying a pure bred, PLEASE make sure they are legit breeders. They should be willing to buy back a dog at full purchase price for the first 2 years, no questions asked. This will ensure they are selecting the right dog for you, whether you are looking for longevity, family companion, working ability, confirmation, search and rescue- whatever. Do not support "greeders" that are puppy mills feeding the animal shelter.
I will get off my soap box now.
