I like this list best (Molly moves up to #4 from 5 on that list )...
The Most Popular Dog Names of 2014 | Rover Blog
Molly is also the name of my oldest son's girlfriend... We have to specify 'Molly the human' and 'Molly the dog'..
..Unless its context makes sense:
Molly ate another xbox controller <- dog
Molly is picking up the younger kids after school <- human
Molly is pregnant <- This one raised some eyebrows last year when Molly the dog was pregnant.
We haven't ran into any other dog named Kevin.
