I live in NJ near Manhattan and always leave from Newark airport. As I'm sure you know, leave yourself plenty of time to get to the airport with the potential traffic en route to LaGuardi. What cruise ship are you going on and when?
Smooth sailing (and flying),

I fly out of LaGuardia about every other week to Miami or San Juan. I've never encountered a dog. Just plan extra time for the crowds going through security. Pack light when it comes to your carry-on.
