Veterinarian John-Paul Carew successfully removed the knife from 6-month-old "Elsie."
The blade was lodged between the dog's esophagus and stomach for four days.
The 13-inch serrated knife was removed last week during a two-hour surgery.
PLANTATION, Florida (AP) -- The veterinarian thought the X-ray was a joke.
Jon-Paul Carew has seen strange items get into the stomachs of dogs before, things like kebab skewers and small utensils. But a 13-inch serrated knife in a 6-month-old puppy?
That was a new one.
"I was just flabbergasted," said Carew, of Imperial Point Animal Hospital in Fort Lauderdale. (Watch how puppy is doing -- 1:34)
The knife was removed this week from Elsie, a Saint Bernard puppy. The dog's owner, Jane Scarola, wrapped it in a towel and put it in a cabinet atop the refrigerator.
"I'm going to frame it and give it to Dr. Carew," Scarola said. "He should hang it. Everybody should know what puppies are capable of putting down their throats."
She thinks one of her six other dogs -- four Saint Bernards, a German shepherd and a Labrador -- somehow got the knife off a counter and it eventually made its way to Elsie.
"She wants to eat everything and anything," Scarola said.
I'm happy she's doing fine
