    Owners of seriously or terminally ill pets are more likely to suffer with stress and symptoms of depression and anxiety, as well as poorer quality of life, compared with owners of healthy animals, finds a study.
  • iconDogs' social skills linked to oxytocin sensitivity
    The tendency of dogs to seek contact with their owners is associated with genetic variations in sensitivity for the hormone oxytocin, according to a new study. The results contribute to our knowledge of how dogs have changed during their development from wolf to household pet.
  • iconWolves 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.
  • iconAre you barking up the wrong tree by sleeping with your dog?
    Let sleeping dogs lie … in the bedroom. That’s according to a new study that’s sure to set many tails wagging.

    New research shows that predation rates of moose have increased near areas of high human disturbance, but low human activity, such as tailings ponds and pit mines.
  • iconAn 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.
  • iconBeetle'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.
  • iconNew therapeutic antibody for dog cancers
    Scientists have developed a new chimeric antibody that suppresses malignant cancers in dogs, showing promise for safe and effective treatment of intractable cancers.
  • iconSuccessful guide dogs have 'tough love' moms, study finds
    Much has been written on the pitfalls of being a helicopter parent, one who insulates children from adversity rather than encouraging their independence. A new study seems to back up this finding -- in dogs.
  • iconLargest-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.

    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.
  • iconWhole 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.
  • iconNo simple way of predicting breathing difficulties in pugs, French bulldogs and bulldogs from external features
    As many as a half of all short-nosed dogs such as pugs, French bulldogs and bulldogs experience breathing difficulties related to their facial structure. However, research suggests that there is no way to accurately predict from visible features whether an apparently healthy pug or French bulldog will go on to develop breathing difficulties.
  • iconNew MRI contrast agent tested on big animals
    Experiments in dogs, rabbits and monkeys show the efficacy and biocompatibility of a new MRI/MRA contrast agent in detecting stroke. This T1 MRI contrast agent based on ultrasmall iron oxide nanoparticles could become a possible alternative to clinically used gadolinium-based agents.

  • iconDog 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.
  • iconSearch and rescue dogs do their jobs despite travel stress
    When disaster strikes, you want the very best tools, functioning at their peak. In the case of catastrophic earthquakes, tornadoes, or even bombings in war zones, those tools are search and rescue dogs. But researchers have found that getting dogs to disaster sites can add to the animals' stress.

  • iconOrigin 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.
  • iconFirst 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.
  • iconFOXI3 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.
  • iconTracking leishmaniasis in dogs, wild animals and sand flies in Brazil
    Researchers have surveyed the environmentally protected area in Campinas, Southeastern Brazil, which has undergone several changes by human action, especially the implementation of condominiums, and revealed that more than one percent of dogs, as well as some opossums and insect species in the area carry the parasite responsible for the most dangerous form of leishmaniasis.
  • iconReal-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.
  • iconDon'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.
  • iconDogs to sniff out chemicals that identify human remains
    New research to help improve accuracy of criminal investigations involves a partnership between humans and their canine coworkers.
  • iconPiglets 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.
  • iconMemory 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.

    Researchers are paving the way for more precision in determining surgical margins for an aggressive tumor common in cats by analyzing tissue contraction at various stages of the post-operative examination process.
  • iconSensitivity 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.
  • iconNatural capital: Holistic management makes ecosystems healthier, people wealthier
    A new study puts a price on ecosystems by recognizing the value of a 'natural capital' asset -- in this case, fish in the Baltic Sea -- and connecting it with holistic ecosystem management to calculate asset values for the interacting parts of an ecosystem.
  • iconDogs 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.
  • iconCensus 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.
  • iconGene finding to eradicate severe blistering disorder of the skin found in dogs
    Researchers have identified a novel gene defect that causes a hereditary blistering disorder of the skin, epidermolysis bullosa, in dogs. Epidermolysis bullosa, found in the Central Asian Shepherd dog breed, occurs also in humans due to an identical gene found in both canines and humans.
  • iconOutnumbered and on others' turf, misfits sometimes thrive
    Evolutionary biologists have long assumed that when an individual of a species wanders into a different environment than it is adapted to, it will be at a competitive disadvantage compared to natives of the same species which are adapted to that environment. Studying fish in Canada, scientists found the opposite.
  • iconDog skull study reveals genetic changes linked to face shape
    A study of dog DNA has revealed a genetic mutation linked to flat face shapes such as those seen in pugs and bulldogs.
  • iconWolves need space to roam to control expanding coyote populations
    Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded, according to a new study. The results were similar across three continents, showing that as top predators' ranges were cut back and fragmented, they were no longer able to control smaller predators.

    Pet dogs provide valuable social support for kids when they're stressed, according to a study by researchers, who were among the first to document stress-buffering effects of pets for children.
  • iconThe family dog could help boost physical activity for kids with disabilities
    The family dog could serve as a partner and ally in efforts to help children with disabilities incorporate more physical activity into their daily lives. A case study of one 10-year-old boy with cerebral palsy and his family's dog, found the intervention program led to a wide range of improvements for the child.
  • iconNovel antibiotic resistance gene in milk
    A new antibiotic resistance gene has been found in bacteria from dairy cows. This gene confers resistance to all beta-lactam antibiotics including the last generation of cephalosporins used against methicillin-resistant Staphylococcus aureus. A transfer to S. aureus which is likely according to the researchers would jeopardize the use of reserve antibiotics to treat human infections caused by multidrug-resistant bacteria in hospitals.
  • iconThe evolution of dog breeds now mapped
    When people migrate, Canis familiaris travels with them. Piecing together the details of those migrations has proved difficult because the clues are scattered across the genomes of hundreds of dog breeds. However, in a new report, researchers have used gene sequences from 161 modern breeds to assemble an evolutionary tree of dogs. The map of dog breeds, which is the largest to date, unearths new evidence that dogs traveled with humans across the Bering land bridge.
  • iconHow dogs interact with others plays a role in decision-making
    Dynamics between familiar dogs may influence their likelihood of learning from each other, new research shows. How dogs interact with others plays a big role in how they respond under conditions that require quick thinking.
  • iconTarantula wolf spiders use their lateral eyes to calculate distance
    A necessary part of any animal's sense of direction is a positioning system, allowing it to have an idea of the relation between where it is and where it wants to go; this is known as odometry. A new study shows that tarantula wolf spiders (Lycosa tarantula) use their posterior lateral eyes and anterior lateral eyes (they have a total of four pairs of eyes) to establish the distance they have traveled.
