Hi,
does anyone know where I can get info on crate sizes and shipping info.
I am sending a puppy to the USA but he has to travel on his own so any info on making his journey go smoothly will be appreciated.
He is going on a direct flight and there will be someone there at both sides to sort him out, me on this side and the new owner at the other.

If you go to BA cargo webpage they have a section with diagrams on how to measure your dog for the correct Crate to fly it in.

It goes nose to base of tail for length - floor to top of ears for height and shoulder to shoulder for width. My puppies went together in the same box being litter mates and I had to do the shoulder to shoulder width X3 to comply with the regulations which meant they went in a clipper 4.

Good luck
