twister I agree, not all parsons are out of control however perky is a JACK russle not a parson, and she came from unknown background, she is definatly NOT out of control! she is a cat she sleeps on the back of the couch and causes the least trouble of the 6, well happy causes the least trouble but perky is right next to her, I have however met several person russle terriers that fight hard, but they are so light that they can be seperated by picking them up by the scruff, a JACK however is heavier, has short legs and a long back, they have strong very well muscled bodys making it near impossable to just pick then up, at least for a small person like me, also a jack russles stomach is so well muscled that they hardly feel anything when being kicked off the other dog, they just slid and continue on with there life, but by no means are they out of control, misty(border collie) starts way more fights then perky she is just tall and light easier to get off the other dog. but that does not mean she is out of control, it just means that misty herself is a nasty little devil
