But can you teach it new tricks? 600-year-old dog puzzles experts

The 600-year-old bronze silhouette of a snarling dog unearthed on Teesside is baffling archaeologists.

The 9in-long "Hound of Hartlepool" was found by Tees Archaeology before building work began on the new Headland Sports Hall.

The dog has now been cleaned up and conserved by Durham University experts who are trying to work out what it is.
