<human>: Provide a brief overview of the text.

To give some background, my wife and I adopted our dog a little over a year ago.  He is a 2 1/2 year old, 75 lb Lab mix, and an absolute sweetie.  When we got him we had no plans of moving out of the US and we had every intention of settling here.  It seems that plan may change and we might find ourselves moving to my wife's home country.  We would like to bring him with us if at all possible.  

I've done some preliminary research and it does seem that it's somewhat difficult, but not impossible to bring my dog with me. My main concern now is how he will react to the trip and the transition.  I don't think I could travel with him in the plane cabin.  So that would leave the cargo hold(It's about a 14 hour flight).  That just seems like it might be traumatic for a dog.  Anybody know what the travel is like for them in the cargo hold? Are there other options that I could look into?   We would also be moving from a quiet suburb to a big city.  So that would be a bit of a change for him.  Our alternative to bringing him with us would probably be to leave him with family in the US.  

Does anybody have any experience with this? Any advice? If we end up moving it probably wouldn't be for another 2 years.  So I would have plenty of time to plan this out.
<bot>: I might be moving overseas.  I have a dog and would like to bring him, but I have some concerns and could use some advice.
