Please dont worry, we flew my 4 yr labby over to Sydney last October and he was fine. He is so spoilt and I really worried about him. The flight is so boring all they do is sleep and if he is lucky enough to end up in Sydney he will be looked after really well. My boy actually gained weight!!! I was given the mobile number of the lady looking after him and I could call her whenever I wanted, she even put the phone to his ear so I could speak to him!!!!

We didnt go to see him as we were told that he would feel more unsettled if we turned up and then left him again, but all dogs are different and you will be advised as to what they feel suits your dogs. When we went to pick him up he was in fantastic shape and had really bonded with the lady looking after him. Hope this helps settle your mind a little. Please feel free to PM me if you have any questions.
All the best
Sarah
