I'm going to have to agree with what Red, Nolu and others said about the socializing situation. Red has been involved with Rotties for a long time and has loads of experience with dealing with these sorts of situations, DA etc. Also, as was mentioned, always be careful around dog parks. You may have a dog that's perfect around other dogs but you cannot guarantee that the other dogs in the park are fine with other dogs. I've seen too many people bring their DR, DA dogs into dog parks thinking their dogs would be fine only to regret it later when something terrible happens. Why take that risk? Anyways, she really is adorable! Can't wait to see more pictures of her.
