I brought my dog, Cosita, back with me this past June. It was fairly easy. I adopted her from SAGA Humane Society. They provided health and vaccination certificates. Your main challenge might be the flight home. American does not allow dogs in the cabin in the Belize region. I am not sure about USAir. When it reaches a certain outdoor temperature the airlines will not carry the dog in the cargo hold due to the danger of the heat. So, fairly easy to take the dog out, assuming you can get a flight for your new friend. SimonB, Kathy at Pampered Paws and Dr. Heather and staff at SAGA were all wonderful resources. Good luck. We love Cosita. She is a part chihuahua who looks like a tiny golden retriever.
