Yes, that's the website I got the Mutt Muffs from. They are very pricey for what they are, but it is worth it for all the looks you get when your dog hops out of the aircraft at your destination wearing a bloody headset ferchrissake! I am not so convinced they are better than stuffing cotton wool in their ears, but you have to have a pretty pliant dog to do that and it is easier to shake cotton wool out.
Lizzie does like to sit on my lap when I fly and is getting quite good. I have to do the rudder pedals obviously and she has a job reaching the flap lever, but otherwise suprisingly little problem. R/T has been a bit of an issue, I guess, but we're working on it.
