This one is tricky. Rescues are complicated sometimes and it can be extremely difficult, if not impossible, to entirety work out the harm they have experienced before being rescued. Sometimes not even Cesar Milan could fix that, but that means as that dogs owner you must be mindful of that dogs potential fight response to seeming innocuous catalysts. I am one of those owners, so I am speaking from experience. No dog park, very structured introductions to other dogs and visitors to our house. That is my responsibility, and she is a great dog within the reality I have created for her. It is exhausting sometimes though.
