Her stance is perfect.
By the standards I mentioned, yes.
I go by Max von Sephanitz' rules published in 1923 with his development of the German shepherd as coupled with my understanding of mechanical engineering as applied to bio-material and structural sciences. I actually took a course in that under Dr. Bill Purves at Harvey Mudd College. That stance places higher loads on the hips than is optimal and requires the dog to squat excessively before launching forward. It doesn't provide good frictional contact with the ground either. You can see the dog adjust for it when it goes into heel.
Von Sephanitz' book has masterful drawings on the topic.
