It's impossible to say who will take on Donald Trump in the 2020 presidential election, but if he is defeated by a Democrat, it's likely that a dog will return to the White House after a multi-year absence.
Whether named Maple, Bailey, Champ or Skye, a dog appears to be a must-have accessory for Democratic candidates seeking to take on Trump, who stands out from his predecessors for, among other reasons, not having a pet.
From the third minute of the speech launching his campaign on April 14, Democratic phenomenon Pete Buttigieg, the mayor of the city of South Bend in the state of Indiana, brought his two dogs to the fore.
"I grew up in South Bend, in the same neighborhood where Chasten (his husband) and I live today, with our two dogs, Buddy and Truman," Buttigieg said.
The couple's two dogs have their own Twitter account with nearly 70,000 followers.

Senator Elizabeth Warren of Massachusetts also placed her golden retriever front and center in her bid for America's highest office, putting the dog on the same footing as her husband.
"Today, I thought I'd bring the two guys in my life: Bruce and Bailey. If anyone wants to stay around and take a picture, I'll be here and we can do that, and Bailey will be out there with his own separate photo line," she said to delighted cheers from supporters.
Photos and videos show her bathing Bailey or taking selfies with the pooch.
Another Democratic hopeful, Beto O'Rourke, has two dogs, Artemis and Rosie, who are the stars of many family photos.
Among others vying for the presidency, Representative Tim Ryan of Ohio is accompanied by Bear and Buckeye, dogs he has referred to as "two of the best friends our family could have asked for."
Senator Kirsten Gillibrand of New York bombarded her supporters with images of Maple, her goldendoodle, a cross between a golden retriever and a poodle.
- National Dogs in Politics Day-
Former Colorado governor John Hickenlooper has a dog named Skye, which he featured in a video on Instagram in which he spoke with his arm around the pooch.
"Hi, I'm John Hickenlooper. This is my faithful dog Skye and I'm running for president," he said.
In a country where people celebrate "National Dogs in Politics Day," man's best friend sometimes plays a decisive role.
Accused of receiving illegal campaign contributions, California senator Richard Nixon defended himself in a television and radio address before 60 million Americans on September 23, 1952.
He assured them that he had accepted only a single gift -- a dog for his children named Checkers.
Thus managing to strike an emotional chord with the country, Nixon saved his candidacy, and the "Checkers Speech" went down in history.
On the other hand, any failure can be expensive in the politico-canine era.
During elections in 2008 and 2012, Republican presidential candidate Mitt Romney was reproached for a dark episode dating from 1983.
In June of that year, the Romney family traveled over 600 miles (1,000 kilometers) from Massachusetts to Canada, with their Irish setter strapped onto the roof rack.
Despite the installation of a windshield aimed at protecting Seamus, the dog suffered diarrhea.
Returning to the 2020 race, of all the dogs in the running, Major and Champ are in the lead, with their master former vice president Joe Biden the current Democratic front runner.
The Biden couple's dogs could then potentially succeed Bo and Sunny -- the Obama family's Portuguese water dogs -- in the White House.
Before Barack Obama, presidents Jimmy Carter, Ronald Reagan and Bill Clinton all had dogs.
Both generations of Bush presidential families also had dogs: Barney and Miss Beazley, George W. Bush's Scottish terriers, even had a website, Barney.gov.
Sully, George H.W. Bush's Labrador service dog, accompanied the former president's casket to Washington, where his funeral was held in December.
