After capturing the first brain images of two alert, unrestrained dogs last year, researchers have confirmed their methods and results by replicating them in an experiment involving 13 dogs. The research showed that most of the dogs had a positive response in the caudate region of the brain when given a hand signal indicating they would receive a food treat, as compared to a different hand signal for "no treat."
Mating with more than one male increases reproductive success for female prairie dogs, despite an increase in risks such as increased susceptibility to predation and increased exposure to diseases and parasites. So why would a female prairie dog take the risk? The answer is simple: female prairie dogs that mate with two or more males rear more offspring than those that mate with only one.
Wolves can learn from observing humans and pack members where food is hidden and recognize when humans only pretend to hide food, reports a new study. The findings imply that when our ancestors started to domesticate dogs, they could have built on a pre-existing ability of wolves to learn from others, not necessarily pack members.
Research has revealed that guarding dogs can significantly reduce conflict between livestock and large carnivores, such as cheetahs or leopards, helping to reduce unwarranted killing of endangered species in South Africa.
