I've personally seen a considerable difference in the dogs behavior after cutting them, but in every case that I have witnessed; it seems to be more benefecial with our hounds than with the cur dogs?
I'm not sure why...
Incidentally, the only dog I ever regretted cutting was a cur. I wish I had some pups off him!
We have far less problems in the box or at feeding times after cutting these hounds. At the same time my curs that have been cut are still just as likely to be the dominate dog around the house, but have never been growley in the box.
I use a blade rather than a band & always will
