I don't have a dog but I would like a small one like this...

and now I know I could travel with it if I wanted to. Maybe I have been under a rock for a while but I saw 5 dogs in the airport these past few days, and one was traveling on my plane! I have never seen this before so it was weird seeing it sitting in a seat more behaved than a human. Luckily it didn't bark so I would rather that than the crying baby. I wonder how much that costs, is it just like any other carry-on?
After writing this I decided to read the American Airlines American Way magazine. At the back were some travel tips including this one, "
Carry on Pets must stay in their kennels and under the seat in front of you at all times. AA assumes no liability for the well-being of carry-on pets."
