I am not at all suprised about George's response when the kids were in danger. Growing up, I had a Jack Russell Terrior. (my mom still does, 15 years old and still crazy as can be). He may only be a dog that stands 8 inches high, by a foot and a half long, but in his mind, he is a german shepherd and will do anything to protect his pack. I remember as a kid I was playing outside with my dad and Pete (the dog), and a coyote comes walking through my backyard. As soon as Pete saw the thing he darted at it, barking his brains out. The coyote took off in a hurry to say the least. Regardless of size, a little white missile running directly at you will get your heart pumping! lol.....
Way to go Jack russels! Awesome dogs! They may be annoying as hell the first five years (YAP YAP YAP, JUMP, YAP, JUMP HIGHER, YAP), they are the best!
And Seagoon- You said it brotha. I know so many people who have bought pit bulls because it's cool, and just totally neglect to take care of them.
I recently bought an Eastern Blood Line GSD. I understand the responsibility of owning a large aggressive dog, and I make sure that as a puppy, he is around as many people and dogs as possible, so he isn't aggressive (when he shouldn't be) when he is fully grown.
