Western Europe
By the 1500’s Europe and its dark ages has gotten left behind when it comes to lapdogs, a gap that the modern renaissance nobility is no less interested in overtaking once again.
The European lapdog is usually small, with lots of fur that can be styled in fashionable ways. Miniature spaniels, curly dogs and dogs with silky long hair are favourites of the ladies. White or piebald dogs in particular are popular. They can be cut and styled in different ways, and although not held in quite the regard of it's Chinese counterparts, they are still spoiled.
Dutchmen bring in the first Chinese style of lapdogs in the 16th century, a dog with short fur, hanging ears, a tail curled over its back and a sharp stop and short face. To begin with these dogs are called “Dutch Bulldogs” for their similarity to the stature and short faces of the bulldogs of the time (more similar to modern Staffordshire Bull Terriers), but it's fairly quickly changed to “Pug”. These new tiny dogs with lots of personality quickly gain favour amongst Europe’s higher classes, and are mixed with a wide variety of dogs to create smaller variants of other breeds.
Despite Foo Dogs being a tightly guarded treasure, very similar dogs did and still do live in families and on the streets of Beijing and other Chinese cities. Even though today we mostly see the long haired variants, as the last chapter shows they historically existed in short coats too. These would be the dogs brought back to Europe by merchants in the 16th and 17th century and called a pug. Although not quite what we think of today when we think of a pug, any dog that was small and had a short face would be called a pug in those days, when the breed of a dog was decided based on looks and not pedigree.
