New research finds three alternative answers beyond errors in handler or dog training that can explain why dogs trained to identify scat for conservation purposes sometimes collect non-target scats.

A specific virus changes dietary behavior of fire ants, leading researchers to rethink control methods for the invasive species.
A new study chronicles an evolutionary tie between wolves and when bull elk shed their antlers.
The reintroduction of wolves into Yellowstone National Park is tied to the recovery of aspen in areas around the park.
Goats can differentiate between human facial expressions and prefer to interact with happy people, according to a new study.
A virtual dog could soon be used as an educational tool to help prevent dog bites, thanks to an innovative project led by the University of Liverpool's Virtual Engineering Centre (VEC).
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.
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 collagen formulation mixed with pancreatic cells is the first minimally invasive therapy to successfully reverse Type 1 diabetes within 24 hours and maintain insulin independence for at least 90 days, a pre-clinical animal study shows.
Most animals have a keen sense of smell, which assists them in everyday tasks. Now, a new study sheds light on exactly how animals follow smells.
Researchers have uncovered new details in how the olfactory epithelium develops. The new knowledge could help scientists prove that turbinates and the resulting larger surface area of the olfactory epithelium are one definitive reason dogs smell so well.
Airlines are not the only organizations grappling with the complexities surrounding emotional support animals. Colleges and courts are also questioning the need for these animals and the effects they may have on students and juries, respectively, according to new research.
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.
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.
By looking into the brains of locusts, researchers have determined how one smell can affect another, and how a locust can recognize a smell even though its brain activity looks different depending on the context.
Dogs infected with Leishmania infantum, a parasite transmitted by the sand fly Phlebotomus perniciosus, are at risk for spreading leishmaniasis infections to humans. A new test provides an easier-than-ever way to test dogs for exposure to P. perniciosus sand flies, and could be used in monitoring the effectiveness of sand fly control efforts.
Many dogs show empathy if their owner is in distress and will also try to help rescue them. Scientists have just tested whether there is truth in the notion that dogs have a prosocial and empathetic nature.
Researchers have found therapy dogs to be effective in reducing the symptoms of attention deficit/hyperactivity disorder (ADHD) in children.
In 2015, a New Delhi-metallo-beta-lactamase (NDM) Escherichia coli bacteria was discovered in two Finnish dogs. A new article reveals that the dogs' owner did also carry the bacterium. This is presumably the first time in the world that the transmission of NDM-bacteria between a dog and a human has been reported.
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. They typically move at night and hide during day, and uncovering their secretive movements could play a key role in reducing their impact as a disease vector.
Both dogs and humans can suffer from ichthyosis, a disorder in which the skin becomes very dry, scaly, and prone to secondary infections. Medical researchers have uncovered new details about one form of the disease and took a step toward developing a topical therapy.
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.
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.
Scientists demonstrated for the first time that horses integrate human facial expressions and voice tones to perceive human emotion, regardless of whether the person is familiar or not.
Dogs are capable of understanding the emotions behind an expression on a human face. This study is the latest to reveal just how connected dogs are with people. The research also provides evidence that dogs use different parts of their brains to process human emotions.
