Have recently moved to Zurich from Houston, Texas - heading back to Houston to get my dog and move him here now that I have found a place to live. I'm booked on United Airlines from Houston through Newark and on to Zurich. It looks like United has a PetSafe program that should track my dog through all of the flights etc. Does anyone have any experience with United/international flights/dogs? Anything good? Anything to watch out for? Any tips for packing him? He's a 10 year old Corgi.
