Strict compliance with specific pet travel rules of carriers is required for airline travel. The maximum weight is typically around 20 pounds for cabin pets. Some snub-nosed dog breeds are prohibited by their travel rules. Airline travel rules require IATA-compliant containers. My bulldog needed to be transported in the cargo space by a Lufthansa flight, which necessitated alternative travel arrangements, and preparation resulted in no last-minute travel denials.

Choose IATA-compliant carriers with due diligence. Measure your pet while standing upright to ensure you get the proper size. Carriers need to have both bolt locks and suitable absorbent liners. The ventilation grids must comprise 16% of the surface area. My terrier used an extra-large crate because of his height. Using the wrong carrier will result in rejection at check-in.

Proactively managing breed-specific restrictions is paramount. Snub-nosed dogs, such as pugs, are frequently prohibited from air transport as cargo. Airlines perceive bulldogs as high risk. Hence, the airline carrier's restrictions should always be verified before transportation. I helped an individual reroute their French bulldog through a pet-friendly carrier. Transportation in temperate months decreases the chances of respiratory problems.

Carefully prepare health certificates. Obtain your certificates at least ten days prior to the departure date. Include the microchip numbers that correspond with the vaccination records. The international flights require a USDA endorsement. My client's cat was delayed in travel because this stamp was neglected. Obtain duplicates and carry them in a waterproof sleeve.
