I think that if your dog is growling at you, you need to look at why, and help them become more comfortable with the situation.
If we had caught Honey's skin in her harness, causing her to be more wary and possibly leading her to growl when we approached with it again, we would need to go back to basics to get her to trust the harness again.
A growl is a sign something is wrong - if your dog were to be growling at you, you need to take steps to solve the thing that is wrong, not tell him/her off for growling. The positive of growl is the fact that you
haven't been bitten - it gives you the chance to solve the problem...
Yes, it would not be a good place to be if your dog was growling at you over everyday things, but the problem is not the growl but the fact that they are feeling frightened or insecure...
