The Yorkshire terrier is named Britain’s dirtiest dog in a bizarre test to find our dirtiest fidos

Dirty puppy! The Yorkshire terrier is named Britain’s dirtiest dog in a bizarre test to find our dirtiest fidos

  • The muddiest dog was the Yorkshire terrier which collected the greatest proportion of soil
  • Scientists used a sample of 30 dogs to find which breed collected the most mud
  • 61% of owners need to give their dog a deep clean every week










You might assume your own dog claims to be among the muddiest in Britain, especially after a winter walk.

But scientists say that when it comes to the sticky stuff, one breed stands head and paws above the rest – the Yorkshire terrier.

A sample of 30 dogs – including a Great Dane, Labrador, Cockapoo, Chihuahua, Lhasa Apso and “wildcard” mixed breeds – were tested to see which collected the most slime.

Each took three long walks with their owners under similar testing conditions, with the mud they collected then cleaned and weighed by scientists.

The muddiest dog was Ollie Mo, a Yorkshire terrier, who scooped up the highest proportion of soil to his own body weight – 14g, or 0.29%.

Evie, a bearded collie, finished second at 0.15% of her weight.

Houndslow, a St. Bernard, picked up most of the soil, but the 42g was just 0.05% of his weight.

The challenge was led by automaker Jeep and soil experts from the James Hutton Institute.

Lorna Dawson of the institute said: “Dog breed and size, environment and weather all influence the amount of evidence recovered.”

A Jeep survey of 2,000 dog owners found that owners spend about an hour and 20 minutes each week cleaning up after their muddy dogs.

Over the course of a year, they spend 23 hours washing their dogs, 24 hours cleaning up their mess around the house, and about 22 hours cleaning their cars.

Every week, 61% of dog owners deep clean their dog at least once, while 35% clean their car after a muddy walk one or more times.

The James Hutton Institute is a recognized world-renowned research organization specializing in earth, crop, water, environmental and socio-economic sciences.

Miss Dawson added: “We are delighted to be working on this interesting experiment with a range of dogs and their owners.

“Using approaches similar to those used in our forensic case work, we were able to disentangle the many factors at play and show some insight into these primary and secondary transference interactions.”
