Updated at the bottom: Surgeons confirm that the leg was saved.

Surgery was wrapping up this afternoon on Gordo the dog. An official at Advanced Critical Care-Los Angeles said veterinary surgeons were working on saving his leg and that the operation was almost complete.

The owners opted to save the pooch's right, rear leg rather than amputate, said hospital representative Shannon Brown.

An outpouring of donations via the veterinary facility's website could cover the cost of the procedure, but that's not entirely clear yet, she said:

“We're thrilled with the support,” Brown said, “but we don't have a final cost for the procedure.”

The dog, estimated to be 1 to 2 years old, was struck by a van being chased by authorities in South Los Angeles about 9:06 p.m. last night, authorities said.
