Wow, that's a lot of moving around the globe! Mind if I ask but how did your dogs react to repeated flying? I've heard of dogs that somehow got out of the crate or possibly were taken out and then escaped, refusing to go back in the crate because the flying had been such a bad experience for them. I've heard a few good things about Dogtainers now so I'm looking forward to their reply.
When they arrived in Dubai - they were really good and looked amazing! My little boy was a little spooked after his first flight but came right after a few days. Their trip to Dubai was a non-stop which was great for me. When they went from Italy to Australia there was one stop and they were taken out of their crates and the crates were cleaned and they were taken for a walk (Dogtainers informed me of this); which I was very happy to hear. When I finally got them home after 30 days in Quarantine they looked amazing and both Mum and kiddies were very very happy!
The great thing with Dogtainers they have agents all over the world - even in Italy they had an English speaking agent. They will answer all your questions and believe me they took away a lot of the stress and worry.
Dogtainers and/or the agents tell you to put a piece of your clothing in with them so they can spell your scent; didn't have any problems with them getting back into their crates - good travellers and well travelled!
