More than 20,000 dogs will take part, with thousands of visitors attending.
And the first pampered pets have been pictured at the competition, with many dressed in their best clothes for the occasion.
One dog stood out from the crowd in a colourful bodysuit, while another wore a blue coat with green leg warmers and a purple hood.
Molly the German Spitz wrapped up in a fleece. A Border Terrier made their entrance in style on a dog-sized skateboard. Two more dogs looked very patriotic in Union Jack onesies.
Meanwhile, a tiny white dog kept out of the cold in a pink stroller.
And a chilled-out Poodle took it all in their stride, resting their head on a bone-shaped cushion as their fur was groomed.
Other owners could be seen using hair spray and brushes to style their dogs.
