My husband and I do a lot of traveling and end up leaving Liesl either with my parents or in-laws. I would love to have her come with us to a lot of places, but refuse to put her "down below" as cargo. Are cavs small enough to fit in those carry-on pet carriers comfortably? Also, I've heard different opinions in terms of how strict flight attendants are with the dogs on board. One woman I talked to wasn't allowed to unzip the bag even enough to let her dog poke his nose out and had to keep the carrier completely under the seat in front of her. Yet, I've heard that others have had their dogs on their lap. Let me know what you all think!
