dogs

Just about everyone loves puppies. But around the country, there's heated disagreement about where, and from whom, people can get one.

While the large national pet store chains don't sell dogs, other chains and shops do. But in several states, including Florida, cities are passing laws that ban puppy sales in pet stores.

At the Petland store in Plantation, Fla., a suburb of Ft. Lauderdale, customers come in all day long to look at and play with the puppies. At this store, in fact, doggie accessories and puppies are all that owner Vicki Siegel sells.

Dogs have an intuitive understanding of fair play and become resentful if they feel that another dog is getting a better deal, a new study has found.

The study, in the Proceedings of the National Academy of Sciences, looked at how dogs react when a buddy is rewarded for the same trick in an unequal way.

We often think about people spreading diseases around the world. This spring, vacationers brought chikungunya from the Caribbean to the United States. Businessmen have likely spread Ebola across international borders in West Africa. And health care workers have carried a new virus from the Middle East to Asia and Europe.

But what about (wo)man's best friend?

At Monday's Boston Marathon, many runners will be on the course to honor the 16 people who lost limbs in last year's bombing. One married couple was among them: Jessica Kensky and Patrick Downes.

Among many dark stories of that day, theirs is among the darkest. They were newlyweds of just seven months when each had their left leg blown off. Their injuries were so severe that they were some of the last victims to leave the hospital.

As part of a series called "My Big Break," All Things Considered is collecting stories of triumph, big and small. These are the moments when everything seems to click, and people leap forward into their careers.

Long before Cesar Millan became the "Dog Whisperer," with TV shows and a best-selling series of books, he had to learn how to ask for a job in English.

In Sochi this week, athletes are competing in a display of human grace and skill. Many will win. Many more will lose, and many tears will be shed.

In New York on Saturday night, athletes of a different breed competed in a display of canine finesse and dexterity. Many won. If any lost, none knew it. Not one shed a tear.

At the Westminster Dog Show's Masters Agility Championship, 225 exuberant dogs dove through tunnels, flew through hoops, leaped over hurdles and wove in and out of poles with the focus of the highest-level Olympic champion.

Our four-legged friends suffer from many of the same cancers that we do. But one type of dog tumor acts like no other: It's contagious.

The tumor spreads from one pooch to another when the dogs have sex or even just touch or lick each other.

"It's a common disease in street dogs all around the world," says geneticist Elizabeth Murchison at the University of Cambridge. "People in the U.S. and U.K. haven't heard of it because it's found mostly in free-roaming dogs in developing countries."

Fishermen around the Northwest are enjoying some exceptional salmon runs this autumn. Puget Sound is teeming with pink salmon and there's a record-breaking fall Chinook run in the Columbia and Snake Rivers.

While there's a serious dog problem in Detroit, the initial results of an effort to count the number of homeless canines in the city indicate there are far fewer than the 50,000 strays that some news accounts have talked about.

For years, PTSD — or post-traumatic stress disorder — has been an issue for military members returning from Iraq and Afghanistan.

But humans aren't the only ones with problems. Military dogs returning from war zones are also showing signs of PTSD. And there's evidence that these canines need some extra tender loving care after their tours of duty.
