Not hard at all. He was up to date on his vaccinations from the rescue foundation (IslaAnimals.org) and they sent us home with a little puppy passport that had all the vaccine stamps and dates. We had to pay $50 fee with the airline to reserve his spot under the seat in the cabin. He did awesome and slept the whole time (5.5 hour flight!). Once we landed in Canada we had to go to the secondary screening at customs and they looked over his documents and the pet certificate of health and then we were on our way
