When would you like your pet to travel?
Contact the airline you choose to confirm that they accept your pet on the flight that you prefer. Some airlines restrict the number of animals they carry on a flight so the more advance notice you give them the better it is.
Transportation of snub nose dogs, such as boxers, pugs, bulldogs and Pekinese, in hot seasons is not recommended. These animals have difficulty in maintaining a normal body temperature in hot weather.
What is your pet’s size and weight?
Only small dogs and cats can travel in the cabin. Some airlines may not even allow them in, and will transport them as special baggage in a heated and ventilated hold. Do not worry, cats and dogs actually travel better this way because it is quieter and they will rest in a darkened environment
Do you have a suitable container for your pet?
It is important you purchase the right sized container for your animal. Airlines use the following indications to ensure the animal has enough space to turn about normally while standing, to stand and sit erect, and to lie in a natural position.
Guidance for Dimensions of Container
The data presented above gives a guideline for ascertaining the correct size for a container. They relate to an animal standing in a natural position.
The calculated dimensions are internal container dimensions.
A) length of animal from tip of nose to base/root of tail.
B) height from ground to elbow joint. A+1⁄2 B = length of container.
C) width across shoulders or widest point (whichever is the greater). Cx2 = width of container.
D) height of animal in natural standing position from top of the head or the ear tip to the floor
(whichever is higher) / height of the container (top flat or arched)
Minimum internal container dimensions:
A + ½ B = Length C x 2 + Width D = Height
Snub nosed breeds require 10% larger container
Food and water containers (troughs) accessible from outside the container are required. The carrier, or government agency, may require that additional food be provided in a pouch attached to the container with feeding instructions.
How many animals will be traveling?
The United States Department of Agriculture (USDA) Animal Welfare Act (AWA) states that “no
more than two live puppies or kittens, 8 weeks to 6 months of age, that are of comparable size and weighing 20 lb. (9 kg) or less each, may be transported in the same primary enclosure via air carrier.” This is a good practice to follow for all animal shipments, no matter what country they are traveling in.
Remember, animals may become stressed and aggressive when traveling by air and should not be placed in the same container unless they are young puppies or kittens. Animals which share the same household may become stressed and aggressive towards each other when traveling by air.
