Buzz: Dogs just seem to get the point

WE KNOW that several animal species align their bodies to the Earth's magnetic field lines when performing certain behaviors such as grazing, hunting or migrating, but until now it wasn't known whether dogs did the same thing. In a two-year study published in Frontiers in Zoology, European researchers proved magnetic sensitivity in dogs by measuring the direction faced by 70 dogs of 37 different breeds when defecating or urinating and comparing the data to geomagnetic conditions at the time. Turns out that when the Earth's magnetic field is calm - only about 20 percent of the daylight period - dogs prefer to line up along the north-south axis.

* Got dust? And dogs? Good news! Your child may have less risk of developing asthma and allergies. A new study suggests that exposure to dust from homes with dogs may change the immune response to allergens and other asthma triggers by affecting the makeup of the bugs that inhabit the gut. Dog-associated house dust can play a key role in preventing allergic inflammation.
