Aggression in Dogs


After years of seeing clients with aggressive dogs, one big lesson I’ve learned is that it’s important to be as optimistic as possible. It’s my job to give realistic assessments of situations, and to help clients safely manage them. It’s also my job to move heaven and earth to help them improve both the situation and their dog’s behavior. If they are committed to making the effort, I am never without hope. Each case has the potential to surprise me with a better outcome than I might have predicted, and surprise happy endings are my favorite kind of success story.
