I wouldn't do it. You don't have time for a dog. Eventually you will give up the training to be with the dog, or you will ignore the dog more to continue training, and may even give up the dog at some point. It's not fair to the dog, and if you're anything like me, you'll have a constant feeling of being pulled in two directions. Why put yourself through that, much less the dog?

There's no rush to get a dog. Finish your training, and when you're in a place where you can be home more, then consider it.
