CASSELTON, N.D. – Boomer may be a buster: Measuring 3 feet tall at the shoulders and 7 feet long from nose to destructive wagging tail, his owner thinks she may have the world's tallest living dog.

Caryn Weber says her 3-year-old Landseer Newfoundland keeps all four paws on the floor when he drinks from the kitchen faucet in her family's farm house in eastern North Dakota.

Boomer can stare into a car window eye to eye with a driver. A 20-pound bag of dry dog food lasts a couple of weeks.

Weber says the fluffy black and white dog "comes into the house and his tail is so high everything gets knocked around."

Weber plans to send Boomer's measurements to Guinness World Records. The previous record holder was a nearly 4-foot-tall Great Dane that died this summer.
