revenge? no. this dog, unprovoked, chewed through a chain link kennel, went into the main yard (where the bandogs are) kicked the CRAP out of a dog twice her size- she literally peeled ALL the skin off the top of his head and the back of his neck. and there was blood EVERYWHERE. no knows why she did it either, those two have never had a problem before. in front of me they act like perfect angels...
