A bomb-sniffing military dog with two tours of duty in Afghanistan under his collar was refused entry on a U.S. Airways flight last week because the pilot feared it could become aggressive. 

Alongside his Navy handler, the 6-year-old German shepherd named Kevin was on his way to help patrol the Democratic National Convention in Charlotte, North Carolina when barred entry on the commercial airliner.

According to the Washington Times, the dog had flown on commercial flights before, sitting beside the bulkhead of the passenger cabin with his handler.

But last Saturday while boarding at the Sky Harbor International Airport in Phoenix, Arizona, the pilot questioned the handler, asking if he was trained to attack.

'During the boarding process, the captain asked the passenger if the dog was an attack dog

'The passenger answered "sometimes." Out of caution, the captain denied boarding. We don’t transport attack dogs,' said Mr Christie.

According to an unnamed source speaking with the Times, handlers are not allowed to release details on military working dogs' training.
