  • iconDog burial as common ritual in Neolithic populations of north-eastern Iberian Peninsula
    Coinciding with the Pit Grave culture (4200-3600 years before our era), coming from Southern Europe, the Neolithic communities of the north-eastern Iberian Peninsula started a ceremonial activity related to the sacrifice and burial of dogs. The high amount of cases that are recorded in Catalonia suggests it was a general practice and it proves the tight relationship between humans and these animals, which, apart from being buried next to them, were fed a similar diet to humans'.
  • iconCancer comparison across species highlights new drug targets
    Cancer genes in mucosal melanoma, a rare and poorly understood subtype of melanoma, have been compared in humans, dogs and horses for the first time. Researchers sequenced the genomes of the same cancer across different species to pinpoint key cancer genes. The results give insights into how cancer evolves across the tree of life and could guide the development of new therapies.

  • iconDogs know when they don't know
    Researchers have shown that dogs possess some 'metacognitive' abilities -- specifically, they are aware of when they do not have enough information to solve a problem and will actively seek more information. The researchers created a test in which dogs had to find a reward behind one of two fences. They found that the dogs looked for additional information significantly more often when they had not seen where the reward was hidden.
  • iconPrototype of robot dog nose
    Every day, thousands of trained K9 dogs sniff out narcotics, explosives and missing people. These dogs are invaluable for security, but they're also expensive. Researchers have made the beginning steps toward an artificial 'robot nose' device that officers could use instead of dogs. The heart of the system would be living odor receptors grown from mouse genes that respond to target odors, including the smells of cocaine and explosives.

    A study analyzed environmental exposures, like pet and secondhand smoke, to determine if they have a role in asthma control among children whose asthma is managed per NAEPP (EPR-3) guidelines. Researchers found that once asthma guidelines are followed, environmental exposures to pets or secondhand smoke were not significant factors in overall asthma improvement over time.

  • iconFresh and raw diets for dogs may have health benefits, study says
    Many dog owners think of their furry companions as part of the family, and now products are available to feed them that way, too. Some owners are moving away from traditional extruded kibble products, instead choosing ultra-premium fresh and raw diets found in the refrigerated aisle. The foods may look more similar to what we'd feed a member of the family, but many of the newer diets haven't been rigorously tested for performance in dogs.
  • iconMore than a label: shelter dog genotyping reveals inaccuracy of breed assignments
    Scientists used genetic testing in over 900 shelter dogs to identify breed heritage in the largest study of its kind. The researchers found widespread genetic diversity: 125 breeds in the sample and an average of three breed matches per dog. The accuracy of shelter staff in identifying more than one breed in the dog's heritage based just on physical appearance was only 10 percent. How breed labels can impact shelter dogs is discussed.

    A new blood test can quickly spots early signs of liver disease in dogs, a study suggests. The test means that fewer dogs will have to undergo invasive liver biopsies.
  • iconSequenced fox genome hints at genetic basis of behavior
    For nearly 60 years, the red fox has been teaching scientists about animal behavior. In a long-term experiment, Russian foxes have been selected for tameness or aggression, recreating the process of domestication from wolves to modern dogs in real time. Today, with the first-ever publication of the fox genome, scientists will begin to understand the genetic basis of tame and aggressive behaviors, which could shed light on human behavior, as well.

    Researchers have successfully attached miniature radio transmitters to kissing bugs and tracked their movements. Also known as triatomine bugs, kissing bugs transmit the pathogen that causes Chagas disease in humans and animals.

  • iconFirst dogs in the Americas arrived from Siberia, disappeared after European contact
    A new study offers an enhanced view of the origins and ultimate fate of the first dogs in the Americas. The dogs were not domesticated North American wolves, as some have speculated, but likely followed their human counterparts over a land bridge that once connected North Asia and the Americas, the study found.
  • iconWolf reintroduction: Yellowstone's 'landscape of fear' not so scary after all
    After wolves were reintroduced to Yellowstone National Park in the mid-1990s, some scientists thought the large predator reestablished a 'landscape of fear' that caused elk, the wolf's main prey, to avoid risky places where wolves killed them. But according to recent findings, Yellowstone's 'landscape of fear' is not as scary as first thought.
