Béla K. in Hungary shares this photo of his 11-day-old puppies. The fur is already smoothing on their muzzles while remaining wavy elsewhere.
This photo showcases the distinctive texture of the Kuvasz coat:
“The hair should be neither excessively curly nor straight, but should...have waves and swirls. In 1924, the official term was fluctuosus, ‘wavy,’ which was replaced in 1935 by undulans, ‘undulating.’"
