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
Scott:You're welcome.It's really difficult to evaluate the gait in a pup this age as to whether or not it's normal or secondary to issues with the hips. If this were an older pup, then I might be a little more concerned but I've seen puppies outgrow bunny hopping. Her narrow stance may simply reflect that her rear still has catching up to do with the rest of her body (often the case in larger breed dogs).At this point, I'd ensure that she's being fed a balanced food labeled for puppies (my preference) or one labeled for all life stages.I'd not overfeed her but keep her on the leaner side (not too thin but not too fat either).I'd provide non-slippery surfaces for her to walk on. Area rugs are good if you don't have carpet.I wouldn't let her jump off and on anything higher than a stair riser.I wouldn't take her for long walks. Exercise is important but she shouldn't go for walks longer than 10-15 minutes at a time.Consider joint supplements such as Dasaquin or Cosequin or a product from Kemin, called Re-Flex Bone and Joint Maintenance (LINK).
