I prefer the Gentle Leader too
We are fortunate here as we have a wonderful make of head halter - 'Black Dog'. It suits a Boxer more than any other brand we have tried. This halter is very light and fine, easily adjusted and does not look in the least bit 'muzzle' like. I'm not sure if they are available outside Australia, but here is the URL
www.blackdog.net.au or direct to the head halter page
