just wanted to add: my sister in law has a very dominant intact pitbull that is VERY aggressive towards anything that eneters his space but is totally in love with his older sister playmate/basset hound. they play together and rough it up but when the 8 year old bh says enough, the pit stops in its tracts and says uncle. they were raised together and when I bring chili into the house it isnt so simple. dominance is a wild dog traight that cant be forgotten...petsin the same household seem to break all other barriers my chili however isnt part of the pitbulls family...even tho I know the pit just wants to play...its too dominant/strong for chili...meanwhile the basset hound as old as she is can put that pit in its place in half a sec.
