I have a large dog that I got here in Germany that I plan on taking with me when I go back to America. Breed bans are no problem, she's a mix between Kangal and Garafiano. I already have the proper crate for her travel, I just would like to know what would be the safest and most comfortable way for her to get there? Is there a really good service that takes care of that? Which service/airline is best? How much would it cost? Are there any size restrictiuons? What companies/airlines should I avoid? Any ideas would be of great help.
