Dogs are man's best friend. They are known to be most loyal animals ever that, sometimes, they are even more admirable than humans. Dogs even become part of our families that we consider them as an extended (even immediate) family member.

In a research published in the journal Memory & Cognition about misnaming, it states that people tend to make blunders on this. However, did you know that dog is the only pet "whose name is substituted for loved ones?" It is because "we think of dogs are human-like family members."

Because of this, it is not surprising that we give such high importance on our beloved canines' names.

According to a press release sent to Nature World News, Bella is the most popular name bestowed to most of the dogs in the U.S. These are followed by Lucy, Charlie, Zoe and Lily.

An interesting theory behind the popularity of the name Bella is said to be inspired by the character Bella Swan from the popular book-turned-movie "Twilight." Meanwhile, the names Lucy and Charlie are classic favorites.

Meanwhile, the most popular breed in the U.S. is the Labrador retriever, with almost 70 percent of Americans favoring this active dog breed. The second place goes to the smallest dog in the world, the chihuahua.

Pitbulls might look scary, but according to a report, many people consider potties to be easy to train, good with children and protective. Welsh corgis, German shepherds and golden retrievers are also part of this hall of fame.

The numbers prove how popular pet ownership is among Americans, and that it is not just a trend or a pastime. Owning a pet will make people happier, reduce stress, and will boost our self-esteem, according to scientific studies.
