Hello Scott, I'm Dr. Deb.
I recently came online and see that your question about Kira hasn't been answered. I'm so sorry that you've had to wait for a response,but if you still need assistance, I'd like to help if I can.
While hip dysplasia can be seen even at this early of an age, it's not a commonly seen problem. I can't entirely reassure you, of course, that she doesn't have this issue but more than likely, the way she walks and sits is not related to this condition. It's just her being a puppy.
She's still young and got quite a bit of growing to do. Her muscle tone/mass is still developing and many pups at this age have problems with stairs.
If she were my pup, I wouldn't be too concerned...not at this age anyway. You can always have x-rays taken but I'd probably wait until she matures more before considering this step.
I hope this helps although, again, my apologies for the delayed reply. Deb
