Hungry dog saved by vets after swallowing 111 pennies...

A Jack Russell terrier, while lacking in common sense, was brimming with common cents.

The beloved pet pooch inhaled a mini-mint of 111 pennies behind its Manhattan owner’s back, and veterinarians had to rescue the ailing dog after its sudden change in diet.

Doctors at BluePearl Veterinary Partners, working methodically on 13-year-old Jack, removed all the coins from the penny-popping pooch’s insides during a two-hour operation. The coins were fished out five at a time, said Jack’s owner, Tim Kelleher.

The Wall Street worker said he knew something was wrong last Friday when Jack began vomiting in their home.

The dog grew progressively worse over 24 hours after ingesting the coin collection while licking up crumbs from a leftover bagel.

“He’s like a voracious Tasmanian devil — if there’s food, he’s got to get it,” said Kelleher, who lives and works in the Financial District.

“He climbed on my desk to get at the bag with the bagel and knocked the change all over the floor. While he was licking up the crumbs, he swallowed the pennies.”

An X-ray showed $1.11 worth of pennies lodged inside the white-furred terrier. And the zinc in the coins posed a lethal threat to the canine cutie’s kidneys and liver. “If Jack would not have had the pennies removed the consequences would have been fatal,” said Dr. Amy Zalcman, who helped treat the dog at the W. 55th St. office.

Kelleher said he let Zalcman keep the change once the pennies were removed. Jack showed absolutely no ill effects from his poorly advised meal.

“He’s doing great,” Kelleher said Tuesday. “He’s driving me crazy again.”
