all the pet relocation companies quoted me around 7k to take my german shepherd from the united states to saudi arabia. I am a student so I only have a few grand for my whole move. I don’t undestand if I get him in the cargo on my plane, how will he survive a 20+ flight with no food, water or potty breaks? would i be able to take him out during layovers? I am super stressed and lost about this whole process and would appreciate any guidance on the matter. Thank you!

he is a german shepherd, male, 3 years old, weighs 82 lbs
