  • iconAre amoebae safe harbors for plague?
    Amoebae, single-celled organisms common in soil, water and grade-school science classrooms, may play a key role in the survival and spread of deadly plague bacteria. New research shows that plague bacteria, Yersinia pestis, not only survive, but thrive and replicate once ingested by an amoeba. The discovery could help scientists understand why plague outbreaks can smolder, stay dormant for years, and re-emerge with a vengeance.

  • iconDogs are more expressive when someone is looking
    Dogs produce more facial expressions when humans are looking at them, according to new research.
  • iconDomestication 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.
  • iconUnraveling 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
  • iconHow 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.
  • iconThe hormone that could be making your dog aggressive discovered
    Thousands of people are hospitalized every year for dog bites, and aggressive behavior is a major reason dogs end up in shelters. Biologists have studied the biology behind canine aggression, specifically the role of the hormones vasopressin and oxytocin.

    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.

  • 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.

    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.
