Cameras go inside the locked-down houses of well-known faces around the country. However, the filming is done by the homeowners' dogs - so-called Snoop Dogs. While the pooches sniff out treats, chew shoes and go for naps, viewers can play along with the guessing game to try and work out which celebrity owns the adorable doggy. The opening instalment features a four-year-old Lhasa apso and an eight-year-old Labrador mix. Narrated by Kevin McCloud.
