As a result of specialised breeding, there are significant differences between field and trial-bred and show-bred lines of Labradors. In the United States, the former are sometimes mistakenly referred to as "American" and the latter as "English." In fact, both field and show types are bred in both countries and all Labrador Retrievers are descended from British lines.<ref>{{cite web|last=American Kennel Club|first=The Labrador Retriever Club, Inc.|title=American vs. English|url=http://www.thelabradorclub.com/subpages/show_contents.php?page=English+vs.+American|access-date=2 September 2012|archive-url=https://web.archive.org/web/20170705101113/http://www.thelabradorclub.com/subpages/show_contents.php?page=English+vs.+American|archive-date=5 July 2017|url-status=dead}}</ref>
