That's good that you like to run and exercise. The dog will like to do that with you.
If you like dating, girls, going out with the guys, sporting events, and anything else where you can't take a dog, you can pretty much forget all of that for around a year or longer.
Owning and training a GSD is not just another mouth to feed or a new hobby you can put down when you get bored. It is a lifestyle change and pretty much most of your life as you used to know it will be over and will now revolve around your new pup/dog.
Think hard about your commitment to this animal and how it will affect your lifestyle.
