Driving will be much easier on them. Probably on you also- traveling with dogs on planes is tough, especially older dogs who have not done it before.
Set up an area in back with bedding for them, stop every few hours to pee and rest and give them a bite to eat if they need. They should do okay- they may not love it, but they'll be fine.
Planes are loud, heavy vibrations, high activity level (strangers, screaming kids, etc), they have to be confined in a tiny carrier under the seat, no chance to potty for long periods of time- at their age, I'd definitely go for the car.
I've worked service dogs for quite a few years and flown with a working dog as well. Even for service dogs, who are trained for it and do not ride in carriers, flying is exhausting. |
