The one I used was called Dutta Corp, The Dutta Corp, and they did an excellent job. They had been recommend to me by a dressage trainer who used to import a lot of horses from Europe. I may have read somewhere they might be transporting the Olympic horses to London, so if that's the case, they must be good! Anyway, I thought they did a fantastic job. They even let me travel with my horse.
I keep hearing good things about Dutta. How did it work to travel with the horse? You were on the same plane? Did you get to see the horse when you arrived?
