From Vetstreet’s Kristen Seymour:

Just as today’s second-grade classrooms are no longer filled to the brim with Jennifers and Jasons, the dog names that were most popular a decade or two ago are no longer at the head of the class.

After checking out the most popular and trendiest puppy names, we decided to try something different and determine which names are on the other end of current trends. Using Vetstreet’s data on close to 1.26 million dogs, we took a peek at which names have fallen in popularity since 2003. Here are the 10 male and 10 female dog names that have fallen the farthest in the past decade.

    Sammy was the No. 24 most popular male dog name a decade ago and fell to No. 66 last year. It’s worth noting that Sam is also losing popularity, falling from No. 14 to No. 35 over the same period of time.

    Shadow, which came in as the No. 51 most popular female dog name in 2003, has now fallen to No. 87.

  • #9 Smokey (Male) / Madison (Female)

    Smokey hasn’t fallen out of the top 100, but after going from No. 43 to No. 87 over the last decade, it still earned a spot on this list.

    Although Luke was the No. 56 most popular name for male dogs in 2003, it fell out of the top 100 in 2012.
