WASHINGTON (AP) — The University of Georgia's bulldog mascot, Uga, gets a special medical procedure to help him fly safely. But many other short-snouted dogs do not fare as well when put on an aircraft, new data shows.

Dogs with pushed-back faces such as English bulldogs and pugs accounted for roughly half the purebred dog deaths on airlines in the past five years, the Transportation Department disclosed Friday.

Overall, at least 122 dog deaths have been reported since May 2005, when U.S. airlines were required to start disclosing them, the department says. The dogs died while being shipped as cargo.

English bulldogs accounted for 25 of the deaths, the single highest number among the 108 purebreds on the list. Pugs were next, with 11 deaths; followed by golden retrievers and labradors, with seven deaths each; French bulldogs, with six; and American Staffordshire terriers, four. Boxers, cockapoos, Pekingese and Pomeranians each accounted for two deaths.

Owners should consult with veterinarians before putting their dogs on planes, the department said. It believes the deaths represent a tiny percentage of the pets shipped on airlines. The department said mixed breeds accounted for four airline deaths and a dozen dogs who died were of unknown breed.
