My dog is 80 pounds and he's a good boy but between the alergies, the fur, the possibility of disrupting other passengers, and the fact that he takes up two seats (a dog would have to be pretty small to comfortably curl up in one seat for multiple hours) I can see why airline companies aren't keen on it.
