What were early versions of the breed often referred to as before the official name adoption in 1870?

Answer

The broken-haired Scotch Terrier

The lineage of the Yorkshire Terrier reveals that the breed went through naming phases reflecting its heritage and function prior to formal recognition. The dogs initially developed by Scottish migrants in Yorkshire for vermin control retained characteristics strongly associated with other terrier types from their origin region. Consequently, these early iterations of the breed were frequently designated by the descriptive name, the broken-haired Scotch Terrier. The official adoption of the name Yorkshire Terrier did not occur until the year 1870, marking a significant milestone in the breed's formal acceptance.
