Very good points brought up in the last two posts. My rescued lab/boxer/and yes, pit, I think, is the sweetest gal in the world. BUT she nipped some big guy in the dog park the other day. Protecting her ball. He was cool about it, I wasn't. I am always aware that she has that side to her, whether she's a lab or a pit! She came to us with a fear of men, and was really doing well, but if I'm next to her and the ball is there too, she's unpredictable with men.

My beloved Thandi, the Rhodesian ridgeback, bit my son more than once. Exactly that--a large dog, had enough of being bugged, and was putting him in his place, like a pack animal will do. Unfortunately, when a big dog does that, it leaves damage. Thandi was unable to be around young children or other animals, especially as she got older. Just something I was always aware of.

I strongly suggest keeping a regular schedule at the dog park, I've found with my two rescues that socializing them in the park has made all the difference. They are still HELL when on a leash if another dog is nearby, but in the park everyone plays well.

Mika, my rescue, is wonderful with children, people, anyone, BUT I always watch her body language.
