Ed (rottweiler/pit cross) has been wearing one of these for a couple of years now and when it wears out he'll have another. It's an excellent design; strong as anything, easy to put on, with a sturdy grab handle and a useful D-ring in front for gentle tugs back onto the One True Path when his attention wanders. It's much lighter than a leather harness, and if he rolls in the mud it goes into the washing machine. The only thing his Person objects to is the velcro label space - the blank option is OK, but a no-velcro-no-label version would be better still.
