I didn't see any significant hip joint problem even the x-ray position isn't standard and good enough.
By viewing the video, I do suspect the problem possible on the knee but I can't say it is because I don't examine the dog by myself.
please ask your doctor to double at knee or other area.
Yes as I told you I did suspect something wrong on the knee. I can't tell anything without a good position of VDand lateral x-ray.
You also didn't mark which leg is which on the x-ray, so I can't tell you which one has problem or both have problems.
Please has good x-ray taken and post here as soon as possible.
I need to see the lateral view of x-ray of knee as I told you in last response.
Please ask your doctor to mark the side of the position. It is a common sense for a doctor.
