Dogs As Carry On Airplane What Do I Need To Know About Taking My Dog On An Airplane?

What do I need to know about taking my dog on an airplane? - dogs as carry on airplane

I mixed Porki one years, and on Wednesday the first flight. I have so many things in my head! Is that reassuring or not?
Should I a kennel soft or hard?
Does this count as my "baggage?
How will you go to the toilet during the temporary?

Help?
