We have already gotten this a few times with Madison, but I sometimes wonder the same thing myself. Madison was a rescue and we know for sure that the guy that owned her parents also had a Pit. I'm not 100% sure if he even knew if her dad was the male Boxer or the Male Pit.
I do not know anything about Pit Bulls. I've read a lot about Boxers since we got Madison and she definitely fits all of the usual Boxer characteristics. But, when she gets excited, her ears go back and her droopy cheeks seem to disappear (especially when she has been running around and her tongue is hanging out). Also, when she lays on her back and starts to chew, her jaw looks like other Pit Bulls that I have seen.
Madison is the first Boxer that I have ever owned and is really the first Boxer that I have been around enough to notice these small things.
So basically, I am asking if your Boxers also do this or do you guys think Madison may be a mix? I really don't care if she is because we weren't trying to find a perfect Boxer, we were trying to save a life, but now that we have her, I have definitely become a huge fan of the Boxer breed.
Here is a link to some pictures of her:

The pictures are from 5 to 9 weeks old. She is 13 weeks old now and is much bigger.
