I had an Airedale a long time ago and she was practically fearless. Very friendly with people, and dynamite on other animals or dogs. They can teach much bigger dogs a lesson in good manners. Good brushing keeps the smell away from them and the breed lives really long. Like other terriers that I have had, she loved an opportunity to fight. I would worry if I had other dogs or other pets at home, but otherwise, there would be no problem at all.
