Japanese airline JAL has imposed a ban on bulldogs after heat-related deaths, the BBC reports. The problem isn't in the cargo hold, where they ride in climate-controlled baskets, but sitting on the toasty tarmac, or in baggage handling areas that aren't air conditioned. All other dog breeds, 60,000 of which flew JAL last year, will continue to be allowed on board.
Bulldogs are particularly susceptible to overheating underneath their collars, as well as from complications related to their flat noses. JAL is the second Japanese airline to ban bulldogs from their flights.
