I had never heard of this until Finkie's recent post about an instructor recommending spraying a disobedient dog with a combination of water and vinegar. Alas, I witnessed a friend doing the same thing to her dog today. What's worse, this occurred at a dog sporting event with public presence (i.e. anyone could have witnessed or overheard what happened). I'm not going to tell my friend how to control her dog (who, btw, deserved what she got), and I'm not going to lose a friend over this, but jeez! I was pretty shocked. Is there ANYONE here who thinks this is justifiable, no matter the dog's behavior?
