An ancient Greek formula of ‘physical perfection’ has revealed the most beautiful dog breeds in the world.
Experts have used the Golden Ratio of Beauty – a mathematical calculation which was devised by the Greeks but has proven accurate for centuries – to calculate which are the most attractive dogs on Earth.
According to their analysis, Scotland’s Cairn Terrier is the most beautiful breed, with an impressive golden ratio score of 88.7 per cent.
The closer to 100 per cent, the more a breed represents a ‘mathematical distillation of beauty’ with its ‘statistically perfect proportions’.
Next on the list is another terrier – the ‘Westie’ also from Scotland – followed by the Border Collie and the Rhodesian Ridgeback.
At the other end of the scale, the least attractive dog breeds are the Shih Tzu, the French Bulldog and the Rottweiler, according to the Golden Ratio.
So how does your pooch rank?
Dating back more than 2,000 years, the Golden Ratio – roughly 1:1.618 – compares the measurements, ratios and symmetry of facial features.
The mathematical principle was used by Leonardo Da Vinci for the perfect human male body in his famous work, the Vitruvian Man.
It has since been adapted by scientists to determine the Greek definition of perfect beauty – with celebrities like Aaron Taylor-Johnson and Paul Mescal scoring highly.
Applying the Golden Ratio to dogs, experts at Money.co.uk found some surprising results.

Lastly, the Pembroke Welsh Corgi is a testament to the wide variety of physical features on display on the Golden Ratio list.
