On the trail of the truffle flavor

Truffles, along with caviar, are among the most expensive foods in the world. Because they grow underground, people use trained dogs or pigs to find them. But the distinctive smell of truffles is not only of interest to gourmets. A group of scientists has discovered that the smell of white truffles is largely produced by soil bacteria which are trapped inside truffle fruiting bodies.

Agonizing rabies deaths can be stopped worldwide

Ridding the world of rabies in humans is cost-effective and achievable through mass dog vaccination programs, an international team of researchers says. A rabies vaccine has long existed. Even so, the disease kills an estimated 69,000 people worldwide -- that's 189 each day. Forty percent of them are children, mostly in Africa and Asia. The disease is spread primarily through the saliva of infecte

Being sheepish about climate adaptation

In a first-of-its kind study that combined molecular and environmental data, researchers performed a search for genes under environmental selection from domesticated sheep breeds. They identified 17 genes that are involved in energy metabolism, endocrine and autoimmune regulation.

New hope for beloved family pets: New blood test for canine cancer

Nearly one out of four dogs will develop cancer in their lifetime and 20 per cent of those will be lymphoma cases. Now, a new user-friendly electronic system for diagnosing lymphoma in dogs in the early stages, and for remission monitoring, has been developed by scientists.

Dogs can be pessimists, too

Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that most would have an optimistic outlook on life. In fact some dogs are distinctly more pessimistic than others, new research shows.

Dogs respond to goal-directed behavior at similar level to infants

Dogs look at a person interacting with a new object longer than a person interacting with a familiar object moved to a different location, suggesting perception of goal-directed behavior, according to a new study.

Iberian pig genome remains unchanged after five centuries

A team of Spanish researchers have obtained the first partial genome sequence of an ancient pig. Extracted from a sixteenth century pig found at the site of the Montsoriu Castle in Girona, the data obtained indicates that this ancient pig is closely related to today's Iberian pig. Researchers also discard the hypothesis that Asian pigs were crossed with modern Iberian pigs.

Cat bites dog: In India's human dominated landscapes, top prey for leopards is dogs

In India’s human dominated agricultural landscapes, where leopards prowl at night, it’s not livestock that’s primarily on the menu -- it is man’s best friend.

Impact of movies on dog breed popularity

The effect of movies featuring dogs on the popularity of dog breeds can last up to 10 years and is correlated with the general success of the movies, according to new research.

When it comes to pit bulls, animal shelter workers intentionally misidentify

Recent research asserts that shelter workers operating in areas restricted by breed-specific legislation (BSL) are more likely to consciously mislabel a dog's breed if they felt it were to increase the dog's chances of being adopted and/or avoid being euthanized.

New cancer drug for dogs benefits human research, drug development

A new cancer drug for ‘man’s best friend’ is helping advance cancer therapies for humans, too. The drug, Verdinexor, works by preventing powerful tumor suppressing proteins from leaving the nucleus of cells, an exodus which allows cancer to grow unchecked. It's the first new therapeutic option for dog lymphoma in more than two decades, potentially offering vets another alternative for treating the

Electronic training collars present welfare risk to pet dogs

The results of a recent study have revealed that the immediate effects of training pet dogs with an electronic collar cause behavioural signs of distress, particularly when used at high settings.

Global snapshot of infectious canine cancer shows how to control disease

While countries with dog control policies have curbed an infectious and gruesome canine cancer, the disease is continuing to lurk in the majority of dog populations around the world, particularly in areas with many free-roaming dogs, researchers report.

New research reveals how wild rabbits were genetically transformed into tame rabbits

The genetic changes that transformed wild animals into domesticated forms have long been a mystery. An international team of scientists has now made a breakthrough by showing that many genes controlling the development of the brain and the nervous system were particularly important for rabbit domestication. The study gives answers to many genetic questions.

Wolves susceptible to yawn contagion: Social bonds may increase yawning contagion between wolves

Wolves may be susceptible to yawn contagion, according to a new study. Researchers suggest that contagious yawning may be linked to human capacity for empathy, but little evidence apart from studies on primates, exists that links contagious yawning to empathy in other animals. Recently, researchers have documented domestic dogs demonstrating contagious yawning when exposed to human yawns in a scie

Sheepdogs use simple rules to herd sheep

Sheepdogs use just two simple rules to round up large herds of sheep, scientists have discovered. The findings could lead to the development of robots that can gather and herd livestock, crowd control techniques, or new methods to clean up the environment.

Education, dog-friendly neighborhoods could tackle obesity

Investing in dog owner education and facilities as a strategy to target physical inactivity and problems such as obesity in both people and their pets. It is estimated that 40% of dog owners don't take their dogs for a walk. In the UK, almost a quarter of households own a dog, but less than half of adults meet the recommended level of 150 minutes a week of physical activity.

Pig pheromone proves useful in curtailing bad behavior in dogs

Androstenone can stop dogs from barking, jumping, researchers report. Androstenone is produced by pigs in their saliva or fat, but Boar Mate androstenone is synthesized in a laboratory. One spray of Boar Mate on Toto was all it took to set the wheels of experimentation in motion.

Forensics research to make cadaver dogs more efficient

Specially-trained victim recovery dogs can perform phenomenal feats in sniffing out the whereabouts of bodies and body parts, even beneath mounds of rubble or deep below water. But now a researcher is investigating ways in which they can carry out their grim but vital tasks even more efficiently.

Injected bacteria shrink tumors in rats, dogs and humans

A modified version of the Clostridium novyi (C. novyi-NT) bacterium can produce a strong and precisely targeted anti-tumor response in rats, dogs and now humans, according to a new report. In its natural form, C. novyi is found in the soil and, in certain cases, can cause tissue-damaging infection in cattle, sheep and humans. The microbe thrives only in oxygen-poor environments, which makes it a t

Animal therapy reduces need for pain medication after joint-replacement surgery

Patients recovering from total joint replacement surgery who receive animal-assisted therapy (AAT) require less pain medication than those who do not experience this type of therapy. Animal-assisted therapy (AAT) has been used in a variety of health-care settings to improve quality of life and physical, social, emotional and/or cognitive health for patients.

Skull shape risk factors could help in welfare of toy dog breeds

Two significant risk factors associated with painful neurological diseases in the skull shape of the Cavalier King Charles Spaniel have been identified by researchers. The findings could help in tackling these conditions in toy dog breeds and could be used in breeding guidelines.

Veterinarians use nanoparticles to deliver cancer treatment in dogs, cats

Veterinarians are testing the use of gold nanoparticles and a targeted laser treatment for solid tumors in dogs and cats. The nanoparticles circulate in the bloodstream and become temporarily captured within the incomplete blood vessel walls common in solid tumors. Then, a non-ablative laser is employed against the tumor.

Social network research may boost prairie dog conservation efforts

Using statistical tools to map social connections in prairie dogs, researchers have uncovered relationships that escaped traditional observational techniques, shedding light on prairie dog communities that may help limit the spread of bubonic plague and guide future conservation efforts.

Humans share fairness concerns with other species

Humans aren’t the only species to react strongly to actions they consider unfair. A similar drive for fairness in monkeys and some dogs may offer insight into people’s desire for equity, according to experts.

Rising temperatures can be hard on a dog's life

Veterinarians say it is important to know the signs of heat exhaustion to make sure your pet isn't overdoing it this summer.

Dog jealousy: Study suggests primordial origins for the 'green-eyed monster'

Dogs exhibit jealous behaviors. The first experimental test of jealousy in dogs supports the view that there may be a more basic form of jealousy, which evolved to protect social bonds from interlopers.

African elephant genome suggests they are superior smellers

Sense of smell is critical for survival in many mammals. In a new study, researchers examined the olfactory receptor repertoire encoded in 13 mammalian species and found that African elephants have the largest number of OR genes ever characterized; more than twice that found in dogs, and five times more than in humans.

Asian genes in European pigs result in more piglets

Pigs that are bred commercially in Europe are found to have a highly varied mosaic of different European and Asian gene variants. The Asian genes in particular result in a large number of piglets in European pig breeds. Researchers now explain that a number of important characteristics of European pigs have Asian origins. They previously demonstrated that the genetic diversity among commercial pig

Dog food goes gourmet: Nine emerging trends in pet food

Four out of five pet owners now consider their pet a member of the family, and consumers are shifting their priorities when it comes to purchasing food for their pets accordingly. One expert writes about recent trends in gourmet pet food in a newly published article.
