UK's Crufts dog show opens with growing global appeal

With plenty of barks, treats and tail-wagging, the world's biggest and most famous dog show got underway Thursday in Britain, with a record number of overseas entries among those bidding for Crufts glory.

More than 20,000 pooches of varying size, shape and personality will descend on Birmingham's National Exhibition Centre for the four-day showcase, with one claiming the coveted "Best in Show" crown late Sunday. Widely regarded as the pinnacle for any canine and its owner, both have travelled in unprecedented numbers from around the world this year to come to heel on Crufts' famous green carpets.
