I've had a husky/german shepherd mix, a Boxer mix, a Vizsla (That dog is insane! Crazy high energy!), an elkhound, and a lab mix that have all loved running. Any dog that is high energy and some medium energy dogs will love running. You must make sure that the rest of your lifestyle supports a high energy dog. Do not just get one for a running partner and then neglect their needs the rest of the time. They need at least 45-60 minutes of exercise every single day (can be broken up into 2 sessions). If you cannot provide that then do not get a high energy dog. This is the reason why there are so many of these dogs in the shelters. People think they know what a high energy dog needs, but then when they get it home they get overwhelmed. Here is a really good guideline for responsible dog ownership:

I have to add, as this is a major pet peeve of mine, keep your dogs on a leash people! It is much more cruel to let your dog be hit by a car than it is to keep them in a fence. If you do not have enough space for a properly sized fence (according to your dog's size and activity level), then you should not have that dog. It is not only dangerous for your dog, it is a danger to other people, children, and animals. Even if your dog is non-aggressive (any dog can bite if provoked), they can cause car accidents by running in front of people (and I know of several people who have died because of this!). Most states also have leash laws, which means it is illegal to let your dog run loose. In my state if your dog causes an accident/is hit not only does your dog get hurt, but you are held liable for the accident. Which means you pay for the damages. In some areas they will fine you or even take your dog from you for letting them loose. Also, you should know that children are just naturally annoying to a lot of dogs, and are often bit by dogs who have never shown aggression before (which is why you should never leave a small child alone with any dog). If anyone is bit by your dog for any reason you can be sued, even if it was provoked. Again, not singling anyone out, this is just one of those things that really irks me.
Ok, rant over (I am one of those crazy dog people)! That said, dogs make amazing exercise buddies. They need exercise and attention everyday so it forces you to get out there even if you don't feel like it. And they are just a bundle of fun!
