Researchers have developed a set of tests that can quantify cognitive changes in aging dogs and accurately detect canine cognitive dysfunction syndrome, a disorder with similar pathology and outcomes as Alzheimer's disease in humans. The findings show promise for both humans and dogs in understanding Alzheimer's progression.
Hyperactivity, impulsivity, and inattention are more common in male dogs and young puppies, researchers say. The findings correspond to age and gender associated with ADHD in humans.
Studying 50 species of primates, researchers found 80% of the species studied performed corpse carrying behaviors as a way to process grief. Following the loss of an infant, some primate mothers carried the body for up to four months following death.
Domestic cats choose not a contrafreeload, a behavior where most animals prefer to work for their food.
While the response to numbers may be an evolutionary trait we share with some animals, our ability to perceive language and digits underpins our advanced mathematical skills.
After 14,000 years of domestication, dogs have an edge in both cognition and people-reading skills over wolves.
