well we cant leave out the german shepherd that mauled a 10 yr old boy because the boy was playing catch with a friend and the dog wanted the ball....or even the pomeranian that literaly ripped a 1 week old baby to shreds cause it thought it was its chew toy
Competition for toys or food or attention, dogs don't always see children the same way they view adults.
We certainly can't leave out German Shepherds and Pomeranians who kill. We'll mention them on the rare occasion they actually kill people. But in the mean time - we're really up to our ears in fatal pit bull attacks.
