Two-year-old Mable has been at Battersea for 476 days and is the shelter's longest-staying resident.She was brought into the Old Windsor centre as a stray in April last year and has spent half her life in kennels.
The six Instagram dogs will have their own stand for the first time.
Between them, the six dogs have more than 300,000 followers on Instagram.
He struggled to adjust to kennel life at first when he was brought in a stray, but has since gone on to live in a foster home.
The cute pooch loves snuggling up on people's laps and following them around.
Although who could blame anybody for choosing a dog that looks good in a bow tie and spectacles.
