  • iconTransmission of NDM bacteria between dogs and humans established
    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.
  • iconKissing bugs kiss their hiding spots goodbye, thanks to tiny radio transmitters
    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.
  • iconProgress in addressing a severe skin disease that affects dogs and humans
    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.
  • iconFirst dogs in the Americas arrived from Siberia, disappeared after European contact
    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.
  • iconWolf reintroduction: Yellowstone's 'landscape of fear' not so scary after all
    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.
  • iconHow do horses read human emotional cues?
    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.
  • iconPeople who feel threatened by vegetarianism more likely to care less about animals
    New research suggests that if people perceive the rise of vegetarianism as a threat to their way of life they are more likely to care less for some animals.
  • iconLarge fenced reserves an effective way to bring wolves back to Scotland
    Research indicates that for wolves to be effective at directly reducing red deer numbers and allowing nature to recover in the Scottish Highlands they may need to be reintroduced to very large fenced reserve.
  • iconPhysiological benefits may be experienced by veterans with PTSD who use service dogs
    A new study shows how veterans with PTSD may benefit physiologically from using service dogs. This study used a physiological marker to define the biobehavioral effects of service dogs on veterans with PTSD.
  • iconDogs can detect agricultural diseases early
    Laurel wilt disease has had a devastating effect on the avocado industry in South Florida in past harvest seasons. Early detection can be instrumental in deterring a widespread infection. The use of scent-discriminating dogs has shown to offer the avocado industry legitimate signs of hope in their fight against the spread of the disease throughout their groves.
  • iconHuman encouragement might influence how dogs solve problems
    A new study sheds light on how people influence animal behavior. Researchers evaluated the behavior of search and rescue dogs and pet dogs when presented with the same problem-solving task. Both sets of dogs persisted at the task for about the same proportion of time, but the search and rescue dogs were more successful at solving the task when encouraged by their owners.
  • iconDogs prefer to eat fat, and cats surprisingly tend toward carbs
    Dogs gravitate toward high-fat food, but cats pounce on carbohydrates with even greater enthusiasm, according to research into the dietary habits of America's two most popular pets.
  • iconDogs can be a potential risk for future influenza pandemic
    Dogs are a potential reservoir for a future influenza pandemic, according to a new study. The study demonstrated that influenza virus can jump from pigs into canines and that influenza is becoming increasingly diverse in canines.
  • iconUpgrading the toolbox for Duchenne muscular dystrophy research with a new rabbit model
    Research to improve our understanding of Duchenne muscular dystrophy (DMD), and the development of new therapies, has previously relied on mouse models. However, physiological differences between the two species has limited how successfully findings in mice can be applied to humans. A newly developed rabbit model, created through the use of CRISPR/Cas-9 genome editing, exhibits greater clinical similarity to human patients than the mouse models currently in use, with huge potential to advance DMD research.
  • iconHow to achieve a peaceful coexistence between wolves and humans
    The persecution of wolves in order to remove them from human settlements has culminated in their near-disappearance in numerous European countries, like Spain and Sweden. Following a recovery of the species, a team of scientists has determined what geographic areas in the Scandinavian country would be most suitable for a redistribution of the specie's range, in the interests of increasing the social acceptance of wolves.
  • iconBlame the mother's gene: Discovery for a blinding canine eye disease
    A new gene for canine congenital eye disease has been identified. Defective RBP4 leads to vitamin A deficiency and abnormal eye development during pregnancy. The study defines a novel recessive mode of maternal inheritance, which may underlie other types of birth defects.
  • iconTick bite protection: New CDC study adds to the promise of permethrin-treated clothing
    The case for permethrin-treated clothing to prevent tick bites keeps getting stronger. In new experiments, clothing treated with an insecticide known as permethrin had strong toxic effects on three primary species of ticks known to spread disease-causing pathogens in the United States. Exposure to permethrin interfered with the ticks' ability to move properly, making them sluggish and likely interfering with their ability to bite.
  • iconCause of E. coli beach closings? Gulls
    Researchers have recently published results identifying the major sources of E. coli breakouts on several beaches on Lake Michigan. They have also researched an effective method of reducing the breakouts and the resulting beach closings.

  • iconHunting dogs may benefit from antioxidant boost in diet
    Free radicals, those DNA-damaging single-oxygen atoms, are produced in spades during exercise. Dogs that exercise a lot, like hunting dogs, may need to consume more antioxidants than their less-active counterparts to protect against this damage. But what diet formulation best meets the needs of these furry athletes? A new study provides some answers in a real-world scenario.
  • iconCarnivores in captivity give birth at the same time of year as those in the wild
    Reproductive seasonality is a fixed characteristic of a species -- researchers have now found that carnivores in captivity give birth at the same time of year as their counterparts in the wild. In some species, the gestation period is shortened in order to provide ideal conditions for the offspring, while for others it is extended.
  • iconFrench bulldogs at risk of various health problems
    French bulldogs, predicted soon to become the most popular dog breed in the UK, are vulnerable to a number of health conditions, according to a new study.
  • iconDogs could be more similar to humans than we thought
    Dog and human gut microbiomes have more similar genes and responses to diet than we previously thought, according to a new study
  • iconHow tumors caused by STD quickly regress in dogs
    The canine transmissible venereal tumor is a contagious cancer that has spread by mating among dogs worldwide. One unique feature of this cancer is that, for unclear reasons, it regresses spontaneously or a few weeks after a single treatment of radiotherapy or chemotherapy. A study shines a light on this mystery, revealing a key role for the immune system in triggering fast cancer rejection in chemotherapy-treated dogs.
  • iconFreezing breakthrough offers hope for African wild dogs

    An international study has shown that mating between domesticated dogs and wild wolves over hundreds of years has left a genetic mark on the wolf gene pool.
  • iconDogs with noise sensitivity should be routinely assessed for pain by vets
    Dogs which show fear or anxiety when faced with loud or sudden noises should be routinely assessed for pain by veterinarians, according to new research. Researchers believe that pain, which could be undiagnosed, could be exacerbated when a noise makes the dogs tense up or 'start', putting extra stress on muscles or joints which are already inflamed leading to and associated with a loud or startling noise.
  • iconFirst evidence of live-traded dogs for Maya ceremonies
    Earliest evidence that Mayas raised and traded dogs and other animals -- probably for ceremonies -- from Ceibal, Guatemala.
  • iconMice change their appearance as a result of frequent exposure to humans
    Many tame domesticated animals have a different appearance compared to their relatives in the wild, for example white patches in their fur or shorter snouts. Researchers have now for the first time shown that wild house mice develop the same visible changes -- without selection, as a result of exposure to humans alone.
  • iconSit, stay, heal: Study finds therapy dogs help stressed university students
    Therapy dog sessions for stressed-out students are an increasingly popular offering at North American universities. Now, new research confirms that some doggy one-on-one time really can do the trick of boosting student wellness.
  • iconHow cats and dogs are consuming and processing parabens
    Many households can claim at least one four-legged friend as part of the family. But pets that primarily stay indoors can have increased rates of diseases, such as diabetes, kidney diseases and hypothyroidism compared with those that stay exclusively outside. Some scientists propose that chemical substances in the home could contribute to these illnesses.
  • iconWho's a good boy? Why 'dog-speak' is important for bonding with your pet
    Scientists have shown that the way we speak to our canine friends is important in relationship-building between pet and owner, similar to the way that 'baby-talk' is to bonding between a baby and an adult.
  • iconBall or stuffed toy -- Do dogs 'know' what they're smelling?
    Dogs' excellent sense of smell is well-known, whether it is in the context of searching for people or for contraband substances. However, the question of how dogs understand what they perceive with their sense of smell has largely been unexplored. Scientists have now found evidence that dogs create a 'mental representation' of the target when they track a scent trail.
  • iconHow are we related? Easy workflow to find gene families
    Researchers have released 'GeneSeqToFamily', an open-source Galaxy workflow that helps scientists to find gene families based on the powerful 'EnsemblCompara GeneTrees' pipeline.

    Bites, kicks, and stings from farm animals, bees, wasps, hornets, and dogs continue to represent the most danger to humans, according to a new study.
  • iconVoice control: Why North Atlantic right whales change calls as they age
    Through extensive listening and analysis of whale calls -- which were recorded by a large collaboration of scientists over the past two decades -- researchers were able to pick up the slow gradual changes in sound production in the marine giants as they age. Looking at spectrograms of the calls, which provide visual representations of the sound, the research team could see the progression of vocal characteristics of the animals from calf throughout adulthood.
  • iconProof-of-concept study reveals feasibility of eliminating rabies in Africa
    Scientists have carried out a mass dog vaccination in Chad and determined its effect on human rabies exposure. The study employed a bio-mathematical method for estimating the transmission dynamics of rabies. The researchers conclude that with political will and the necessary funding, elimination of rabies is possible in Africa.
  • iconCracking the genetic code for complex traits in cattle
    The global 1000 Bull Genomes Consortium identified the genetic basis for accurately predicting the complex trait of height across cattle and dairy breeds by pooling large genomic datasets and phenotypes collected from 58,000 cattle. The team validated their findings using the DNA of a wild auroch, the ancient ancestor to all cattle and dairy breeds, and, in a world first, demonstrated the genes influencing height in cattle also influence the trait in humans and dogs.
  • iconBrain training for old dogs: Could touchscreen games become the Sudoku of man’s best friend?
    Spoiling old dogs in their twilight years by retiring them to the sofa and forgiving them their stubbornness or disobedience, doesn’t do our four-legged friends any good. Regular brain training and lifelong learning create positive emotions and can slow down mental deterioration in old age. Physical limitations, however, often do not allow the same sort of training as used in young dogs. In a new study, a team of researchers led by cognitive biologists propose computer interaction as a practical alternative. In the training lab, old dogs responded positively to cognitive training using educational touchscreen games.
  • iconNearly one in three pugs has an abnormal gait
    Nearly one in three pugs has an abnormal gait, which in turn is linked to other health issues, finds a Swedish study of owners of the breed.
  • iconFat cat? Here's how much to feed to lose weight
    Does your cat lay around all day, only getting up to eat and visit the litter box? Chances are, he's overweight. Maybe you've switched to the 'diet' cat food or tried feeding him less, but you might have noticed it's not easy to get that weight off. A new study explains what it takes to get kitty to slim down.
  • iconFemale cats are more likely to be right-handed, researchers discover
    Researchers have found that female cats are much more likely to use their right paw than males.
  • iconHunting dogs as possible vectors for the infectious disease tularaemia
    Tularaemia is an infectious bacterial disease that is life-threatening for rodents, rabbits and hares, but which can also infect humans and dogs. While contact with contaminated blood or meat makes hunters a high-risk group, the frequency of infections among hunting dogs has not been much studied. Researchers have now confirmed a relevant prevalence of infections in Austrian hunting dogs following a serological study in which seven percent of the animals tested positive. This could lead to more intense debate as to whether the often asymptomatic animals represent an additional risk of infection for people.
  • iconCanine distemper confirmed in Far Eastern leopard, world's most endangered big cat
    The Far Eastern or Amur leopard (Panthera pardus orientalis) is already among the rarest of the world's big cats, but new research reveals that it faces yet another threat: infection with canine distemper virus (CDV).
  • 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.
  • iconExperts raise concerns over raw meat diets for cats and dogs
    Experts are warning dog and cat owners to be aware of the risks associated with feeding their pets raw meat-based diets, instead of the more conventional dry or canned pet foods.
  • iconMost dog treats exceed recommended daily energy allowance
    Most commercially available dog treats contain a range of undefined ingredients, including sugars, and often exceed the recommended daily energy allowance for treats ('complementary feed'), warn researchers.
  • iconCommitted to relatives: Hounds and wolves share their parasites
    Grey wolves, as all wild animals, are hosts to a variety of parasites. The presence of grey wolves in German forests has little influence on the parasite burden of hunting dogs, according to a new study.
  • iconSorry, Grumpy Cat: Study finds dogs are brainier than cats
    The first study to actually count the number of cortical neurons in the brains of a number of carnivores, including cats and dogs, has found that dogs possess significantly more of them than cats.
