Pets actually handle travel very well, however, there are a few things you can do to prepare your furry friend for their trip
Familiarise your pet with the carrier
Let your pet become familiar with the pet carrier for a few weeks before travel by leaving it in its' normal living space. This will reduce the stress of travel as your pet will become accustomed to the carrier being in it's natural environment.
If your pet has never adapted well to travelling in a carrier you may find the use of herbal, over-the counter remedies help. There are several calming products on the market (many use valerian, lavender or other natural essences) which you can use before travel to induce a feeling of well-being around the carrier. You can also place their favourite toys and blankets in their box so they are surrounded by familiar smells.
Your pets' health
Reduce the quantity of food within 24 hours of travel but make sure it has enough water.
Take your dog for a walk before leaving for the airport
Give your pet a a light meal 2 hours before placing your pet in the Pet Carrier
Ensure the water bowl in the Pet Carrier is full prior to delivering your pet to the airport
Sedation and use of Tranquillisers
Most airlines, and countries, do not permit the use of sedatives and tranquillisers on animals due to the potential for adverse affects during transport. If sedation is to be administered for valid medical reasons it must be done under the direction of a veterinarian and the administration of the drugs - including time and dosage level - be noted on the health certificate. If such medications are to be used this should only be done in instances where trained individuals, appropriately certified / licensed to administer these drugs, will be accompanying the animal and so are able to take appropriate actions in the event of adverse events.
