Bulletproof Vests For Dogs
A third-grader’s idea saves lives
  My morning ritual involves Grape Nuts cereal, a cup of tea, and an assessment of the day’s possibilities based on the cover story in my local paper, The Arizona Daily Sun. If the cover story is good news, charming, funny or positive in any way, I consider it a good omen for the day. If it is bad news, depressing, dull, or a downer for any other reason, I take immediate action by temporarily...

Super Bowl Sniffers
Dogs help keep the big event safe
  The Super Bowl is an exciting event, but like any big gathering, it poses security risks. Where there are security risks, there are often human-canine teams whose job it is to secure the area and keep it safe for everyone.   Bomb-sniffing dogs (and their human handlers) from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are working long hours searching for explosives in Dallas....

Some Dogs Love Guys
What is it about them?
  Some dogs seem to adore men. They may be very fond of women and perfectly responsive to them, but an extra level of joy comes to them when interacting with men. We’ve probably all met dogs like this—they just love guys, especially guys who pay attention to them at all. No matter how many great women are in their lives and how wonderful their relationships might be with these females, there’s...

Old Dog Bone Fragment Found
What does it mean?
A graduate student studying the diet and nutrition of people living in Texas between 1,000 and 10,000 years ago has found evidence that those people were eating dog meat. Samuel Belknap III was sorting through dried human waste and found a bone that DNA tests suggest came from a domesticated dog, not a fox or wolf. The bone was found in a pile of human excrement and had the orange-brown color...

Chihuahua Survives Owl Attack
His winter coat may have saved him
Chico the Chihuahua survived an attack by a great horned owl. In one sense, he was very lucky because a four-pound dog is easy prey for large owls that are capable of killing and eating much larger animals, such as skunks and raccoons. On the other hand, Chico was unlucky, because owls are usually deterred from attacking small dogs by the frightening presence of a human, and Chico’s guardian was...

“Little Hugo” the Dog Causes Controversy
Venezuela and Columbia in conflict over soap opera
Venezuela and Columbia are two countries that have long had a complicated relationship. Serious matters (such as accusations by one country that the other country was harboring Marxist guerrillas with the intent of overthrowing the government of the first country) strain the relationship. So, too, it seems, do less important problems such as a soap opera made in one country that doesn’t show the...

Does Tail Length Matter?
Robot dog helps answer this question
  Dogs communicate with their tails in ways that are more complex than people thought even a few years ago, and new studies continue to reveal more about the information that tails convey. Many people have wondered whether dogs with docked tails or naturally short tails are less able to communicate than dogs whose tails are long and have not been docked.   In a recent study called “Behavioural...

Language Ability of a Dog
It goes way beyond a big vocabulary
[Editor's update: A February 9 episode of Nova will feature Chaser.]   In a recent study in the journal Behavioural Processes, John W. Pilley and Alliston K. Reid have demonstrated an impressive level of language ability in a Border Collie named Chaser. It’s certainly easy to be most impressed by the fact that she knows the names of 1,022 objects, which she was taught over a nearly three-year...

Burglar Goes Through Doggy Door
Homeowner shoots the intruder
  The great thing about dog doors is that they allow access in and out of your home. That is also their biggest drawback. A man entered a home in Oklahoma City through a dog door, apparently with the intent of robbing it, but instead, he was shot by the owner of the house. Though he got away, he was later apprehended at a convenience store when the clerk saw that he had been shot and called 911....
Good Dog: Studies & Research
Yawns Are Contagious!
Catch one from your dog.
Dog Yawns
A new study provides the first scientific evidence that dogs yawn in response to human yawns. The contagious nature of yawns has previously only been demonstrated in humans and other primates, but in a recent issue of Biology Letters, scientists Ramiro M. Joly-Mascheroni, Atsushi Senju and Alex J. Shepherd report that dogs can also “catch” human yawns. The dogs in the study each spent five...
