Limo is in need for some serious anger management. She can't stand it when I pull up next to the pasture and Lester comes up. This is the same thing we have to deal with at home when Peanut or any other dog comes up to us while we sit on the couch or bed. Oh and she does it when another dog comes up to her too. She growls, licks nervously and shakes uncontrollably. Sometimes the whites of her eyes go red too.
We've tried our best to "rehabilitate" her, but she seriously goes into that "Red Zone" dog that the Dog Whisperer talks about. We found that forcing her to be submissive and holding her down till she gives up doesn't work at all. It makes it worse. Kicking her out of the room and putting her in a time out works the best.
