3 muts (mixed unknown terrier).
1 (actually known) 1/4 american bull - 3/4 american staffordshire terrier (looks like your tan am bull but a little more slight, he is only 85 lbs) Last alarm, and possibly the last thing an intruder will see, he is very serious about guarding his house
2 Chihuahua / datschund (?) mix (18 lbs, 85 lbs of stupid, was supposed to be pure breed, but daddy had to have gotten in under the fence and he is almost positively dats.) First thing heard, you'll never see him in the dark, he is black
3 Cattle dog (???) - 40 lbs of love and energy. Rescue with no history Second thing heard, sounds vicious, but no harm will come.
