Genetic study uncovers evolutionary history of dingoes
A major study of dingo DNA has revealed dingoes most likely migrated to Australia in two separate waves via a former land bridge with Papua New Guinea. The find has significant implications for conservation, with researchers recommending the two genetically distinct populations of dingoes be treated as different groups for management and conservation purposes.

Domestication has not made dogs cooperate more with each other compared to wolves
Following domestication, dogs should be more tolerant and cooperative with conspecifics and humans compared to wolves. But looking at both in more naturalistic living conditions, however, speaks for more cooperative behavior of wolves. Researchers now show that the wild ancestors are excelling their domesticated relatives in teamwork. In an experimental approach dogs but not wolves failed to cooperatively pull the two ends of a rope to obtain a piece of food.

Unraveling the genetics of disc disease in dogs
Since the early 1900s, veterinarians have observed intervertebral disc disease -- a common cause of back pain, rear limb paralysis and inability to walk -- more frequently in dogs with short legs (dachshund, French bulldog, and Pekingese to name a few.) But they couldn't pinpoint why -- until now.Why short-legged dogs more likely to develop painful disease

How rabies can induce frenzied behavior
Scientists may finally understand how the rabies virus can drastically change its host's behavior to help spread the disease, which kills about 59,000 people annually. A new study shows how a small piece of the rabies virus can bind to and inhibit certain receptors in the brain that play a crucial role in regulating the behavior of mammals. This interferes with communication in the brain and induces frenzied behaviors that favor the transmission of the virus.

Wolves understand cause and effect better than dogs
A rattle will only make noise if you shake it. Animals like the wolf also understand such connections and are better at this than their domesticated descendants. Researchers say that wolves have a better causal understanding than dogs and that they follow human-given communicative cues equally well. The study provides insight that the process of domestication can also affect an animal's causal understanding.

An alternative to wolf control to save endangered caribou
The iconic woodland caribou across North America face increasing predation pressures from wolves. A short-term solution to caribou conservation would be to kill wolves. But a new government policy looks at reducing the invasive species moose numbers propping up the wolf population. Researchers have now evaluated the effects of this policy on the caribou population.

Beetle's best friend: Trained dogs most efficient in monitoring hermit beetle larvae
Considered at risk of extinction, hermit beetles need to be efficiently monitored. However, due to their life cycle, standard sampling is unreasonably time-consuming and quite damaging to both the species and their habitat. In searching for a solution, scientists suggested that trained dogs might be more successful.

Largest-ever study of pets and kids' health finds no link
A large body of research has reported an association between the pet ownership and better health among children. But a new study that is the largest-ever to explore the issue contradicts the common thinking. Researchers did find that children from pet-owning families tended to have better general health, but those differences disappeared when factors such as family income and family housing were considered.

The truth about cats' and dogs' environmental impact
US cats and dogs cause 25-30 percent of the environmental impact of meat consumption in this country. The nation's 163 million cats and dogs eat as much food as all the people in France. People should keep their pets -- and keep feeding them meat -- but there may be steps pet owners can take to reduce their environmental impact, says a researcher.

Whole genome sequencing identifies cause of zoonotic epidemic
For the first time, researchers have used whole genome sequencing to identify the cause of a zoonotic infection that sparked a national epidemic. Researchers describe their use of whole genome sequencing to determine the cause of a respiratory disease that ripped through a population of native horses in Iceland several years ago.

Dog walking could be key to ensuring activity in later life
Regularly walking a dog boosts levels of physical activity in older people, especially during the winter, a new study has shown. Researchers found that owning or walking a dog was one of the most effective ways to beat the usual decline in later-life activity, even combatting the effects of bad weather. Dog owners were sedentary for 30 minutes less per day, on average.

Origin of modern dog has a single geographic origin, study reveals
By analyzing the DNA of two prehistoric dogs from Germany, an international research team has determined that their genomes were the probable ancestors of modern European dogs. The finding suggests a single domestication event of modern dogs from a population of gray wolves that occurred between 20,000 and 40,000 years ago.

First genomic biomarkers in extracellular vesicles in veterinary patients
Important biomarkers have been found in extracellular vesicles in dogs with myxomatous mitral valve disease and congestive heart failure. This is the first biomarker discovery based on extracellular vesicles in a veterinary disease. These findings could provide important insight into the molecular basis, diagnosis and therapies for myxomatous mitral valve disease in dogs, as well as mitral valve prolapse, a similar disease in humans.

FOXI3 gene is involved in dental cusp formation
Hairless dog breeds differ from other dogs not only by lacking a coat, but also in the number and nature of their teeth. Scientists studied the skulls and teeth of pedigreed hairless dogs from the collection of the Phyletisches Museum of the University of Jena. Thus, they furthered our understanding of the involvement of the FOXI3 gene in the development of teeth - not only in hairless dogs, but potentially also in other mammals including humans.

Real-time vapor analysis could improve training of explosive-detecting dogs
With a sense of smell much greater than humans, dogs are considered the gold standard for explosive detection in many situations. But that doesn't mean there isn't room for improvement. In a new study, scientists report on a new, more rigorous approach to training dogs and their handlers based on real-time analysis of what canines actually smell when they are exposed to explosive materials.

Don't lose sleep over sharing your bed with your pet or kids
About half of all pet owners share their beds or bedrooms with their pets. Studies about co-sleeping are limited to the bedtime arrangements of adults, or parents and their children. Researchers say that society regards both human-animal and adult-child co-sleeping with apprehension. These concerns should be set aside because both practices have their benefits, says the lead author of a new study.

Piglets prefer new toys, behavior study shows
We can't help but be tempted by new things. We see it in a child's eyes when she opens a new toy, and feel it every time a new version of the iPhone is released. It turns out our preference for shiny, new things is pretty universal throughout the animal kingdom. Yes, even piglets prefer new toys.

Memory for stimulus sequences distinguishes humans from other animals
Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities. Despite these differences, however, it has been difficult to identify specific mental capacities that distinguish humans from other animals. Researchers have now discovered that humans have a much better memory to recognize and remember sequential information.

Sensitivity to inequity is in wolves' and dogs' blood
Not only dogs but also wolves react to inequity -- similar to humans or primates, suggests new research. Wolves and dogs refused to cooperate in an experiment when only the partner got a treat or they themselves received a lower quality reward. The sensitivity to inequity is not likely to be an effect of domestication, as assumed so far. It is rather a behavior inherited from a common ancestor.

Red and eastern wolves are probably not recent hybrids
A research team is calling into question a 2016 study that concluded eastern and red wolves are not distinct species, but rather recent hybrids of gray wolves and coyotes. In a new comment paper, the team argues the study's genomic data and analyses do not definitively prove recent hybridization -- but rather provide support for the genetic and evolutionary distinctiveness of red and eastern wolves.

Dogs help in breast carcinoma research
Cancer of the mammary glands in dogs is very similar to human breast carcinoma. For this reason, treatment methods from human medicine are often used for dogs. Conversely, scientific knowledge gained from canine mammary tumors may also be important to human medicine. Researchers were able to show how similar these tumors are in both dogs and humans.

Census shows which mammals survive in forests surrounded by sugarcane plantations
A census of medium and large mammals found in 22 forest remnants surrounded by sugarcane plantations in the state. They found approximately 90% of all the species of mammals expected for São Paulo State but in smaller forest fragments, the researchers recorded only 20 percent - 50 percent of the species expected to occur across the region. This means that up to 80 percent were locally extinct in some cases.
