Definitely!! Get an ortho specialist on board. You live in the capital of Canada, and I got to believe you have some good very good university vet teaching hospitals with-in reach.

A shallow hip socket can be genetic, she was born with it, or perhaps due to a chronic dislocated hip joint. Bur one reason for hip dysplasia is from shallow hip sockets :-(

Now FHO surgery is done for Leggs Perthes disease which arises from necrosis of a small artery to the femoral head. The head of the femur essentially over times can dis-integrate.

It sounds like the vet is not going for a full hip replacement, but just deepening the acetabulum of the pelvus where the femoral head is meant to fit snugly into.

This type of surgery is certainly worthy of a second opinion from an ortho surgeon, or another ortho surgeon if you have not already seen an ortho surgeon

I wish you much luck and a very successful surgery.
