A surprised woman found a giant dog had been drawn on her patio doors - by a slug!

The artistic creature left the trail on the door of Ann George, from Kennington.

Mrs George said: "I spotted it on the conservatory window this morning and thought it was a bit different."

Multimedia consultant Ann said the slug's masterpiece even saved it from death.

She added: "The artistic slug nearly had salt poured on it but after I realised what it had created I thought I'd leave it alone!"
