In their place are Charlie, Alfie and Ruby For many pet owners, their dogs and cats are as much a part of the family as the human beings. So much so that when it comes to deciding what to call them, traditional choices such as Fido and Felix have given way to fashionable baby names. A study of more than 50,000 pet names has found that the most popular for both cats and dogs was Poppy - which was also the 13th most popular name for a baby girl last year, according to the Office for National Statistics. In their place are Charlie, Alfie and Ruby - three names that appear in the top 20 list for both babies and pets. The decline of traditional names is demonstrated by the fate of Rover and Fido, which were both in the top ten in the 1970s but have fallen to 840 and 1,480 respectively in the study by John Lewis Pet Insurance. The Harry Potter books, children's TV and celebrity choices seem to set the trend for our four-legged friends. Popular names for dogs include Charlie and Lola, from the BBC CBeebies cartoon series; Peppa, from Peppa Pig; Dora, from Dora The Explorer; Woody from the Toy Story films; Winnie, from Winnie The Pooh; and Minnie, after Minnie Mouse. Harry Potter inspires both cat and dog lovers with Harry, Luna Lovegood, Dumbledore, Fleur Delacour, Draco, Lupin, Severus and Dudley all appearing on the list.
