The study, published in Scientific Reports, suggests that engaging with TV could provide dogs with an enriching experience.
A recent study by researchers at Kyoto University found that dogs across all age groups did not exhibit preferences for generous or selfish individuals, despite their ability to eavesdrop on another dog's interactions. This suggests that reputation formation may be more complex than previously thought in animals like dogs.
A study led by Virginia Tech found that volunteer dog-handler teams can effectively detect the elusive egg masses of the spotted lanternfly, an invasive insect damaging farms and forests across the eastern and central United States. With proper training, dog owners can turn their pets into powerful partners for conservation.
Researchers trained two dogs to distinguish between sebum swabs from people with and without Parkinson's disease, achieving sensitivity of up to 80% and specificity of up to 98%. The study suggests that dogs could help develop a quick, non-invasive method for early detection.
A new study found that acquiring a dog during the COVID-19 lockdown had a short-lived boost in cheerfulness but no long-term positive effects on human well-being. Losing a pet also did not leave a lasting impact on its former owners' well-being.
A new study on ancient dog DNA shows that dogs slowly spread southward alongside early farming societies in the Americas. The research found that all pre-contact dogs in Central and South America descended from a single maternal lineage.
A study found that six breeds are significantly more likely to get diarrhea than generic crossbreeds, while two breeds are less likely. Most dogs recover quickly from diarrhea, but around 38% require antibiotic treatment.
