The Labrador Retriever! 
In the build-up to the Westminster Dog Show this weekend (more on this later), the AKC has released the list of the most popular dogs of 2012. To no one’s surprise (at least at this blog) the Labrador Retriever reigns as most popular. The German Shepherd(#2) and the Golden Retriever (#3) were runners up. Chihuahuas, alas, have fallen off the Top Ten.
Miss Congeniality has yet to be announced.
Labs are such versatile dogs I think they will have a long reign at the top.
