The village's pub has been getting a makeover off-screen in recent months, but has its grand re-opening in tonight's (June 15) episode.
Dawson, who plays Darren Osborne, told Inside Soap: "The old set had lots of nooks and crannies, so often people in the background weren't needed for every shot because they'd be out of sight of the camera.
"But now everyone can be seen - there's nowhere to hide - so pub filming days are like one big party. We get excited and everybody messes around. There's usually someone shouting, 'Shut up!' It's mayhem."
Viewers will see Jack Osborne (Jimmy McKenna) become infuriated in the next few days as the Savages take up residence in their new houseboat just outside The Dog.
Dawson added: "[Jack] asks Darren to find out when they'll be moving the boat, but Darren's not all that bothered because Dodger is his mate.
"So Jack tells the Savages that if they don't move their boat, he'll take them to court because they're putting his livelihood at risk. And this is just the beginning of the rivalry between the Osbornes and the Savages."
