What you need to teach him is not to bolt out everytime a door is opened. And by chasing him makes it a game.......bolt out door....I get to have people chase me. You never chase your dog. So scooting out the door he knows whats coming. Put a long leash on him or stout cord so he doesn't realize that someone is attached then have someone open the door as soon as he makes for it give a little tug back on the leash and tell him in a stern voice NO. Repeat this a few dozen times and hopefully he will catch on or at least learn respect for the doors from people he lives with. Pugs are stubborn so patience. Door ettiquette should be learned at an early age by all dogs that includes opeinng car doors. I presume from the way you talk there is a bunch of traffic in and out of your house this makes things really hard to keep a dog that likes to bolt out the doors in. It will take effort on everyones part.
