PREVIEW: Big Dog Britain, Channel 4

The world has gone dog mad, but sales of the very biggest breeds are in decline. Why are Great Danes losing out to French bulldogs in the popularity stakes?

This programme meets the owners who are overshadowed by their pets, to find out why we're in danger of overlooking our larger canine friends. We meet the Bones family and their Newfoundlands, the Mathers family and their Irish wolfhounds, and the owners of Great Danes, English Mastiffs and St Bernards, to help us find the answer.

Big Dog Britain airs Thursday 01st July at 10pm on Channel 4.
