KTVT reports that "we learned that 5000 pets are injured or die on airplanes every year. We first received the support of a local humane society and then took a dog named Rex on a series of flights around the country. We had temperature and humidity sensors inside the kennel and traveled on the same aircraft as Rex. We had Rex examined by a veterinarian at every destination and was always in good health. One airline lost the dog, another left him in the rain, another left him alone and without water, another left him on the hot tarmac when it was 90-plus degrees outside."
