8. Bentley for Male, Olive for Female -Bentley didn’t make it into the top 100 until 2010, but since then it has risen to No. 58. It’s even more popular for male dogs, with a spot in the top 10, so it’s one to watch for kitties. Olive landed at No. 56 in 2012 after a fairly recent entrance to the top 100 back in 2008.
