Which is the most owned dog breed and the less?

I personally think the most owned is the golden retriever, maybe not. Help my sane curiosity?

There are more popular breeds like Golden Retrievers, Labradors and German Shepherds. But I don't think there is a most "less" owned dog breed, all have a different amount of popularity.

Labrador is the most popular breed worldwide running up is the Golden retriever. The least owned would be the Catalburun.

According to the AKC registry, Labrador Retrievers are the most registered and therefore most owned dogs.American Foxhounds and English Foxhounds are on the bottom of the list and least common.http://www.akc.org/reg/dogreg_stats.cfm

Chihuahua's are the most owned closely followed by the Golden Retriever.
