The only thing "retarded" is you shifting the discussion from intensity to "food possessive behavior."
The OP was talking about KILL-possessive behavior, not "food" ...
My dog Stormbringer could be petted while he ate dog food, no problem ... but he would NOT let you get near a KILL or a BONE he had.
Let one of your dogs kill something, or give it a dead rabbit ... and try to take it away from them ... and you might be in for a surprise
