My Elkhound would run at the drop of a hat! Basically chalked up to the Nordic breed type behavior. He would come back whenever it worked but, he loved people so much, they wound up taking him in the two times he got away (more than a run just up the street).
Once, when he was about 9 weeks old, the collar we had was still a little big for him he slipped his head out. He looked down at the collar, up to me holding the leash not attached to him anymore, down at the collar, back up at me with a spark in his eye that he knew
he was free. He took off like a bat out of hell!
The first time he got away, we were in one of the off-leash dog parks in Calgary practicing one of the training methods for off-leash/sticking around. Basically your to let him get ahead with a little distance, then you duck and hide, so that the puppy panics when it turns around with you not in sight - or so it's supposed to go.
Nope. He turns, notices we aren't there, and bolts! Freedom! He went to one of the neighboring houses, started to play with the kids, their dog, their neighbors kids, etc. Happy as a clam. They kept him overnight, and turned him into the pound the next morning. The second time he got away was from our yard - the Meter reader left the side gate open. Basically the same result, but just around the block from us.
Elkhounds have the same temperament - great with people, and especially kids, but not so great with other dogs (supposedly by both males and females, and most issues with the same sex). I can see where it would be an issue because our Elkhound was very friendly, and very friendly with other dogs to the point where he was pushy about it. Never one to start a fight, elevate a fight, or even get in a fight, but he would sometimes get other dominant breeds a little uptight with his incessant sniffing and playfulness.

Yes, I know. A life jacket on a Dog!?! He loved the water. To a point. That point was to the bottom of his chest. Basically he liked to wade. Hated to swim (he is a barrel chested breed, and I've heard while some can and do like to swim, most don't because they're not built/balanced to). But he loved to be in the canoe. We weren't sure how much he would panic being out in middle of the lake, especially if he ended up in the water out there.
