Our guard dog takes his job very seriously, and should you attempt to break through the steel-reinforced doors or otherwise attempt to gain access to our home, a merciless fate awaits.
When he gets ahold of your ankle (not if, but when) you're in serious trouble. There is no force in the known universe that will prevent him from stopping you via exsanguination. You're gonna bleed to death because of an ankle-biter.
I think it's the terrier in him; once he latches on, he shakes and rips, and once blood starts flowing, he goes full-auto. People always thing that it's the pit-bulls or other big dogs that they have to be concerned about. Not so: it's the ankle-biting terriers that do the most damage.
Man, I like this dog.
