Thanks for the replies, guys! Connor is the kind of dog that will grab the leash while being walked and chew it! If he is in the back seat, he will just chew the h#ll out of his harness, webbing or not. There doesn't seem to be a spray substance in existence that tastes bad enough (though stick antiperspirant seems to work some) for my taste bud challenged boy. I wish there was a indestructable harness out there. It would be worth its weight in Gold!
