Believe me, it would be easier to fly with the dog, but it's just one of those moving scheduling things. He has to be out of his house by the end of the month, but he's got to finish some work in LA in November. His job requires him to drive all over SoCal, and he'll be staying with family members in Pasadena, Laguna Niguel, San Diego, etc. He is also planning on a couple of nights in hotels, and probably sleeping in his car for a few nights. I can't make it down since I've got things to do and sitting in a car watching him work isn't one of them. Me sleeping in a car on the streets of LA is just never going to happen, ever, either.
Anyway, he feels that it will be less stressful on the dog, and him, if the dog has an actual home for the month instead of living out of the car.
The dog is probably juuuuust a little too big to go under the seat as well, so I figure she'll be in a cargo hold whether I'm on the plane or not.
