When my dogs race out the doggie door at night and start barking at passers-by, I figure they're just doing their job–warning ne'er-do-wells to move along and not linger by my gate. After all, there are plenty of seedy characters wandering the dimly-lit streets of midtown and downtown Tucson at night. If you live near the US-Mexico border, the seedy characters your barking dog encounters could be much more dangerous than drunken students, hookers, or small-time dope dealers.
After the jump, watch what this Bisbee dog found outside of her fence.
