Thank you for the input, I was starting to panic.
I hope you are still checking in on this post.
The left hip looks very good (the left is on the right side of the x-ray). The right one looks loose, with a shallow socket - definitely some issues there. BUT I would not rush into surgery just now.
According to the vet, the shallow socket is the main problem, that is leading to a flattening of the femur head and bilateral articular incongruity.
i would start swimming that puppy for exercise to help tighten up the hips. The xrays are a little crooked as well, which can be misleading on interpretation . Other then walking funny any other symptoms? Also I would see an orthopedic surgeon for a consult before making any decisions on cutting this puppy.
He presented Ortolani positive sign on both legs.
Like I said, he has accentuated cow hocks, the hocks even cross when walking, particularly when is a little tired.
Other symptoms are lameness, plus he always sits and lies down on his side, never straight, and always get up with his front legs first after lying down. He is on anti-inflammatory meds for 7 days (today is the last day) and we walk much better with the meds, which indicate that he is in pain walking off-meds.
The vet recommended physical therapy (hydrotherapy) to build muscle do prepare for a femoral osteotomy.
But I will ask for a 2nd opinion like you said.
