Following the death of a dog on board a recent flight, United has spent the last month reviewing their PetSafe program. Changes include not allowing any pets to fly to hot-weather destinations like Las Vegas in the summer and only allowing dogs and cats to fly in cargo, they've banned dozens of breeds from also flying in cargo.
"We are doing this to further minimize risk and ensure the comfort of pets we fly," Charles Hobart, a spokesman for United Airlines, told People. "We flew all sorts of animals. Geese, foxes, leopards, you name it, we pretty much flew it. That will change moving forward. We'll only fly dogs and cats as pets that belong to our customers."
The airline is still reviewing its policy on breeds allowed to fly in the cabin.
The breeds listed are the most susceptible to respiratory failure.
