I have a cat and I want to take her with me to Romania and I need to know the requirements and costs. She has a pet carrier already.

I have a 12 wk old Coton de Tulear puppy (similar to a Bichon or Havanese). I know you do not want to allow the puppy to jump on the furniture or be anywhere above the ground because the puppy may become dominant. But what about the car seat? I bring my puppy in her carrier in the car. It only fits on top of the back seat, not on the floor. Is this the same as allowing her on the sofa? Thanks.
