i read spaniels and beagles have always been on top of the list for bites...i can see pit bulls being #1 for kills but am sure the total count can be done with your fingers.

i have been around several (never owned one tho) and all were/are among the most chill dogs i've had the pleasure to meet! i believe it's mostly environment, and part genes as to what makes pits killers...all dogs bite. but the pits i've known were all very intelligent, loyal/protective and fun! some home owners' policies won't cover if there's one in the home tho...something to check into.
