Veterinarian Stephen Cutter of the Ark Animal Hospital in the Northern Territory said the frog underwent emergency surgery to reattach its skin to its back after the amphibian was run over by a lawn mower, The (Brisbane) Courier-Mail reported Tuesday.
Cutter said the frog would not have survived for long without the surgery.
"It was a pretty horrific injury," he said. "It basically took the top layer of the skin off and did some internal injuries."
"But from day one she fought to live. It's very lucky to be alive," Cutter said.
He said the frog, dubbed Victoria after Victa brand lawnmowers, "looks great" after a month of recovering from her ordeal at wildlife refuge Nina's Ark, near Batchelor.
