In the 1941 standard, a much larger emphasis was placed on the description of head than in the 1921 version, which ended up being part of the reason chows began trending towards being seen as a “head breed”.
Decades later in the 1980’s, the Chow Standard needed to be rewritten from the ground up, to emphasize the importance of evaluating all points of the animal equally, including balance, soundness and correct breed type,.
The smooth coated variety was omitted from this version for reasons I’m still researching.. The smooth coated variety was returned to the standard during the big rewrite in 1986, with many thanks to the Society for the Preservation of the Smooth Chow Chow for their dedication to returning the smooth to the standard
