In my experience, seeing is believing.
I take my dog lots of places where there are lots of people. I always carry treats with me, and almost always we end up "performing" tricks for someone. We really gather crowds at parks or little league games.
The best thing you can do is to take your pup to age appropriate training, and keep going.
Along with obedience teach cute tricks like shake, roll over, wave, spin, balance the ball on your snout, crawl, roll (rolling a ball along the ground with your nose) walk backwards, etc.
Make her a model dog so that everyone who meets her will love her.
Inevitably after meeting her and having fun with her, people will ask what breed she is. Smile a big smile and say she's half pitbull half rottweiler.
I do have to wonder about the idiots that bred their dog, the chances that their pit went in heat and the first and only dog that got to her was a rott? Perhaps they were going to make a fortune on designer dogs? A pitweiller? And nobody wanted one?
At our shelter about a month ago two litters of pups were dropped off, one border collie/aussie pups and one havanese/shitzu. Do you call those a haveashit? I am almost sure someone thought they were having designer dogs and when they could not sell them in the paper they just dumped them at the shelter. Well one of the litters brought in distemper, and our shelter was closed for adoptions for three weeks because of it.
I get so damned mad at people I just wanna scream.
I am glad your Mae found a great home and thank you for finding great homes for the others too. Please pass along all advice you get here to the other proud new parents.
