Oh, I wouldn't hit Dafner now.
For one because she doesn't bite me, but also because I know that 'Auch!' and walking away would be more than enough punishment for her, now. Initially walking away would've been a wrong answer, and just saying 'auch' not effective enough.
Those dog collars are crazy, if you think about it..which most people don't, I guess. One wonders whether people are just lazy, or if they truly believe they have a special breed of dog, called "uncontrollable". Uhm...NO, you just can't face up to the fact that you lack leadership qualities. Strange world..blame the dog/horse for our mistakes and shortcomings.
