i'm not really a specialist of dog species

so i had to look up what a jack russel terrier is.

doesn't look too threatening to me, but perhaps if i were wearing body armor and armed with military weaponry, i'd think differently.

Haltom City police Sgt. Terry Stayer said Friday that a preliminary report on the incident showed that the animal was aggressive.

uh-huh. aggressive enough to... pee on your boots? scratch your ankle? put a tear in your BDUs? what exactly?
