You can carry small animals on airlines for a fee, as long as they are in a closed kennel. Or you can check them. Remember that flights are usually not that long either.
I was once on the Crescent in coach. I had just boarded in the middle of the night when this little dog crawled up under my feet. I picked it up and asked around if anyone had a dog but no one answered. When the conductor came around to take tickets, I told him I had a dog, so he asked around and it just turned out to be the woman in front of me. Maybe she didn't hear me. The conductor, unfortunately, had to let her off the train. I think she had just let the dog out to stretch it's legs or something. I'm not sure.
On my recent Canadian trip, there was a couple that brought a large dog with them. He was checked in the baggage car. On long breaks they were allowed to go walk him. Also I think they were able to access him while the train was moving. But still, the Canadian can sometimes not make station stops for hours at a time. It was only the major station stops that we made a long enough stop for them.
