Does anyone have any experience of flying with dogs? Apparently a friend of a friend brings his dog back to the US every summer for a couple of months holiday and I'm wondering what kind of experience that is for the dog? I'm not talking about lap dogs travelling in the cabin, but more the bigger dogs who have to travel in the hold. My guess is that it's not pleasant, but I don't know. Perhaps someone on here has relocated or some of the breeders have had dogs travel?
