Well, I'm absolutely a sucker for anything Japan produces (obviously).
They produce fantastic hunting dogs- animals that are all at once, scent AND sighthounds, and a variety of sizes. Many of these animals are still used today for purposes that existed nearly 6000 years ago. Shibas, and Kai Ken are still used as boar hunters even now!
I find the Japanese aesthetic incredibly pleasing as well. Shiba Inus, Kai Ken, Kishus, Hokkaidos, and Akitas are just a few of the native Japanese breeds that have very distinct, clean, beautiful looks. The Japanese state that these dogs should be "a symphony of triangles," and I think they truly hit the mark.
With so many breeds that look like a variation on one theme (Nordic-types with small, triangular prick ears, curly tails, and double coats), one might be surprised to see that Japan also produces breeds that vary quite distinctly from this norm. The Tosa Inu is, to my mind, one of the most pleasing looking mastiff-type breeds, I've ever seen. These dogs are massive without being course or garish. They still maintain a Japanese aesthetic sense that I have difficulty explaining, but really do enjoy. They are absolutely beautiful animals. And for those that enjoy toy dogs, Japanese Chin are *truly* wonderful little companions. They're beautiful animals, extraordinarily loving, yet they have a slightly imperial air that always reminds you of their aristocratic beginnings. I've never been a "toy" person...but I've really fallen in love with this breed since meeting some fantastic examples as of late.
And for a second pick, I can't help but agree with the people who chose OZ!! I'm such a sucker for the Aussie breeds- so much looking forward to adding an ACD into my life. What I REALLY love about these breeds is how absolutely functional their standards are. There is a reason for EVERYTHING in the ACD standard- down to coat color.
