When Christina Ricci landed at JFK yesterday, she was as compliant as can be -- not so her petite pooch.

TMZ was with Ricci every step of the way after her cross-country flight, even when Ramon -- her "baby" -- wanted to relieve herself. But she had performance anxiety (the dog, not Christina) and couldn't quite do her thang.
