Have you measured her?? Hanna is about 22.5 inches which is almost top of the standard (23 max) and I think she is tiny. However that was due to the fact that around my area there are many badly bred boxers who are taller and bigger. So she is smaller than some of the one locally here, however she is within standard and they are not.
Best to measure her from the withers to the ground.
