I took both of my dogs overseas to the UK for vet school. They were both mixed breeds of a medium size. Do your research on pet shipping companies and the services they offer. It can be expensive. I did everything myself because I am cheap. I bought cargo space about 2 months before I flew and the appropriate sized international flight accepted crates. You can also rent crates from the airlines. I trained my dogs to get used to their crates as much as possible. I outfitted mine with the biggest water bowls I could and used two per crate. One of my dogs was aggressive so I had a reason to make sure no one opened the crate during transport to check on her. I broke up my flight to the UK into two flights. Both left at night when the temperatures would be cooling off and they could spend the least amount of time in a crate. I flew Chicago to NJ, spent the night there and then the next afternoon NJ to Glasgow. I made sure the hotel knew I had two dogs in crates and would need assistance. One of my dogs was 9 and the other 6. I had all of my paperwork in order and travelled with copies just in case. The receiving country are the guidelines to need to research and the requirements of the airline. You will need to know what tests, microchip, vaccinations and health certificate you will need. I flew United and they were amazing, this was shortly after several brachycephalic dogs dies during transport. The people that actually handle to the animals were extremely nice and explained everything. I watched both of my dogs be loaded onto the planes, pick a window seat not he side of the plane where they will be loaded into cargo. If there is a live anything in cargo the cargo area is pressurised and kept at a constant temp I think like 55-60 degrees. Cargo is the safest for animals traveling. I was a nervous wreck and if my dogs were with me by my seat, they would have picked up on that and been miserable as well. As much as you think you are a reassuring force with your animal, you will find out in school that when the owners aren't there, animals are okay. For almost all international flights regardless of your animal being a service animal or not, it's probably too big. Does the dog really need to come with you? Is taking a Husky to the Caribbean the best idea? If you have to evacuate in the event of a hurricane is your dog gonna be able to come with you? What about getting settled first and bringing your dog over at a better time of year?
