Ok I have now traveled about 5 times with Merlin in cargo (once over 7 hour flight time) so here's just my 2 cents.
- Merlin was not traumatized in any way or medicated in any way. Get them used to the crate, drive around in the crate in the car, play loud music...they'll be fine.
Other than needing to pee and being tired, Merlin has never had a problem flying or even been crazy to get out of his kennel. Just stay calm.
- freeze some water halfway as deep as their dish (have TWO dishes on the crate door)
- Attach paperwork to crate on where your dog is going
- Stick some weewee pads down under bedding
- Bring babywipes/clorox wipes/paper towels in your carryon with you to clean any potential mess so you aren't loading a gross crate with you to your car/travel location
Alaska airlines and Delta will put a little ticket on your dogs kennel which a flight attendant will give you when you sit down to prove your dog is on the plane. I also reminded attendants of this.
I have had great experiences flying with him, overall..especially with staff who assured me that it is climate controlled and safe down there. Plus just with his behavior, I know he isn't traumatized. He still hops in his crate at check-in ready for his peanut butter kong
