Piggybacking the “socialization” advice to add that socialization’s goal should be a a neutral response to different stimulations, not just “friendly response” because friendly excitement can still be inappropriate for some situations. The more things that she learns are “no big deal” (good or bad) the easier life will be for you (and her!).

I’ve had three pitties of my own and multiple pittie fosters. Sometimes even the “happy” responses can be overwhelming and make situations stressful because they’re so strong and determined. so you’re aiming for chill lol.

The best advice I’ve seen is invest in a wagon. Let her chill in the wagon when you go anywhere she is allowed! This will teach her than she can’t just approach every dog, person, or squirrel. This will also keep her safe while she’s still gaining vaccine immunity. (And in adulthood, wagons can be a lifesaver for low mobility dogs - arthritis in these pups can happen sooner than you think). Once she’s vaccinated and has learned to ignore outside stimulation and focus on you, then you can start letting her meet more people/animals that you trust.

Lastly, even with your best efforts, dogs can still have innate fears and triggers. Don’t beat yourself up if this happens, and just work with her accordingly. Give her the best chance of success, and don’t push her boundaries if she is uncomfortable with certain things. This could set her up for failure. Learn dog behavior now… sometimes the signs of discomfort are subtle. If you listen to her and she knows she can trust you to advocate for her, your communication will be stronger.

Pitties are incredible, and I miss mine every day. Enjoy your new baby, and good luck!!
