For the dog run area having a low masonary perimeter wall capped with steel fencing and a "jail" style door might work well for the dog and be visually appealing from motor park area. Then install a dog door in the mudroom exterior door for convenience.
Installing a perimeter invisible fence has been one of my better moves. Being able to let the dogs out when ever they want and not have to worry about them breaching the perimeter is good peace of mind. And after a couple months they don't need to wear the invisible fence collar to obey the perimeter.
