No one can help you with this, it is up to you. I find it hard to be without a dog, but I also understand the constraints that puts on us.
We are fostering a dog now, but I am not sure she will ever get adopted. With that, we have the same issue, you cannot just fly to 'xyz' as we have a dog and worse than that she has some issues that I would not wish to impose on friends...
Your call... I would have trouble leaving my dog home for a month without me... my wife? that is a different story
