I was very surprised to see at least 3 dogs on our last flight coming home from Orlando. Is it the "norm" for airlines to allow dogs onto its flights? My husband is really allergic to dogs and if one of these dogs was next to him, he very possible could have a bad allergic reaction. Would the airlines move his seat if a dog was next to him? Aren't the dogs usually put in a special place where people are not in contact with them?
