Is it time for airlines to add a "beware of dog" warning to their pre-flight safety instructions?That  idea may be on the minds of 122 US Airways customers this morning after  a dog got loose on their flight and bit a passenger and a flight  attendant.
Though the injuries were minor, the incident prompted  the pilot to divert the Newark-to-Phoenix flight to Pittsburgh for an  emergency landing, 
The Associated Press reports.
"The  captain felt in the interest of safety, it was better to land and have  them looked at than continue on," US Airways spokesman Todd Lehmacher  tells the Pittsburgh 
Tribune-Review.
The  culprit: a 12-pound Manchester terrier named Mandy, who got loose after  her owner took her out of the cage, according to the 
Pittsburgh Post-Gazette.
Apparently, the dog's "sedatives began wearing off" and it became agitated, the 
Tribune-Review says, citing Allegheny County police Inspector David Walsh.
A man sitting next to the dog's owner tried to calm the dog.
That's when the trouble started, according to the 
Tribune-Review. The  paper writes the dog bit the man, got loose "and then ran up and down  the aisle of the plane barking. A flight attendant who grabbed the dog  also was bitten."
The 
Post-Gazette says the bite victims  were treated by airport medical personnel. They then got back on the  plane in Pittsburgh and continued on to Phoenix, according to 
Tribune-Review.
However,  separate transportation was arranged for the dog's owner -- identified  only as an 89-year-old New Jersey woman en route to Palm Springs, Calif.
US Airways officials note the carrier does allow small dogs to be brought on board -- 
for a $100-each-way  fee  -- if they fit in a carrier small enough to go under the seat in front  of the passenger. But US Airways adds that its rules require passengers  to keep the pets caged in flight.
