The mournful, pleading, eyebrows-up expression dogs make is so familiar that we have made it into an idiom: puppy-dog eyes. A new study suggests it's yet another example of dogs' ability to communicate with people, one that evolved as the animals were domesticated from ancient wolves at least 15,000 years ago.

What does a cat do when nobody's looking? One way to find out is to set up a pet cam to spy on kitty at home. Another way is to put little video cameras on cats' collars, set the animals loose and examine hours and hours of footage.

Strolling with a leashed dog can impart a significant and rising injury risk in older adults, new study finds.

Lil Bub is a kitten-size cat with 2 million Instagram followers, a talk show, a stage production, an album and a book. The new study reveals the weird DNA behind what is often described as her magical appeal.

There is a spot on 14th Street NW in Washington that is often littered with the remains of takeout chicken. In the text vernacular of dog walker Perry Edon III, it is a "bone zone."

Thousands of kids around the world have been asking that question for four years - and using camera traps to get some wild answers.

Steven Lindsay, a public health entomologist at Durham University in England, has been researching malaria control for decades. His preferred approach, he says, is to "sit on the boundaries," drumming up ideas that others might not. So it's perhaps unsurprising that his latest project was inspired by the baggage-claim area at Dulles International A...

The young golden eagle on the operating table showed no outward signs of trauma. An X-ray had revealed no fractures.

Goats get a lot of love on the Internet. They get less in the pages of animal cognition journals. The darlings of such research tend to be primates, whales, dolphins, dogs and horses. Goats, on the other hand, "are not considered to be the smartest cookies," said Christian Nawroth, an agricultural scientist at the Leibniz Institute for Farm Animal ...

Justice is an 8-year-old American quarter horse who used to be named Shadow. And when he was named Shadow, he suffered. At a veterinarian's exam last year, he was 300 pounds underweight, his black coat lice-ridden, his skin scabbed and his genitals so frostbitten that they might still require amputation.

The largest grizzly hunt in the Lower 48 in more than 40 years is set to open next month in Wyoming, and more than 7,000 people applied for a chance to kill one of up to 22 bears.

As a raccoon spent much of Tuesday climbing a 25-story skyscraper in downtown St. Paul, Minnesota, the world watched, terrified that this suspense story would end in a tragic plummet. (It didn't.)

President Donald Trump and North Korean leader Kim Jong Un captivated the world on Tuesday morning with a historic summit that seemed to lower the prospect of a devastating global war. Not long after, a Minnesota raccoon captured some of the attention and seemed to raise the prospect of a collective national heart attack.

It is not clear exactly when or precisely how, but at some point thousands of years ago, dogs became the world's first domesticated animal.

Lwiro Primates, a rehabilitation center and sanctuary for nearly 200 orphaned chimpanzees and monkeys in Congo, shared a heart-melting video of a baby chimp rescue on Wednesday. In it, tiny Mussa sits in the lap of a pilot who is flying the animal from Virunga National Park to safety with Lwiro.
