It’s travel season again — when people ponder the safety of putting pets on planes. Many animal professionals warn against it — particularly during the summer, dead of winter and holidays, when temperatures and traffic can take their toll.

Unless your pet is relatively small and has a flattened muzzle that can obstruct breathing, he’s likely to be stowed in his carrier in the cargo hold. But the hold does not have the same pressurization, climate control or lighting as the main cabin — and no one’s around. That means your pet could face unmonitored risks at cruising altitude. Pre-flight sedation is also risky, because it can compromise breathing and decrease a pet’s ability to regulate his body temperature.

But if flying with Fido or Felix is your only option, consult your veterinarian for important ways to maximize your pet’s in-flight safety.
