‘Inside’ – about which the Portsmouth artist has been leaving hints and clues across the city – will run from Friday, July 16 to Sunday, August 1.
The News exclusively revealed that it takes place in the old casino in Osborne Road, Southsea.
My Dog Sighs said: ‘I knew the casino because the owner had let me paint the outside for a previous project.
‘When he let me inside I instantly knew how perfect it was for me and was delighted that I was given permission to use it.’
Take a sneak peek at what to expect from the exhibition in these photos from PA.
Tickets are £10 for adults, £5 for concessions and children go free. They are available from mydogsighs.co.uk.
