No arguments to any of the above. Had a 110 pound Chesapeake that was built like Arnold in his prime, an amazing hunting pard and a family shadow too. Like most that have shared a blind and gone afield with a good working retriever, I have some amazing stories....
Fast forward to about four years ago.... My sister is a veterinary tech and the clinic where she was employed ended up with a pit after someone wanted to be like Michael Vick. The vet was going to put the dog down but all the techs that cared for her protested and launched a campaign to find her a home. My love & I agreed to foster the dog for 30 days until a suitable owner could be found to keep her from being euthanized. Yah, I know.
The dog was delivered by my sister and another vet tech with a care package that included a Dog Whisperer DVD on aggressive breeds (what did we get ourselves into???). As a result, I've researched the breed to gain a better understanding and had many Cesar Millan DVD evenings with my love. In due course, I watched both our dog and our family change for the better. At the time the dog arrived, #2 son was a HS freshman and had begun to implode. Witnessing my love calmly and assertively correct a pit and/or quell a snarling teen that outweighed her was well worth overcoming both stereotypes....
Accordingly, they are not for everyone. An unfortunate number are relegated to a compensatory role, or worse, by owners who either squander the breed's inherent stalwart and resolute nature or fail to recognize their true strengths. Perhaps, someone reading this would be willing to making a positive difference in the life of one dog...
... and in return, they would unconditionally do the same for you and yours....
