When should you neuter your dog to avoid health risks?

A new, 10-year study by researchers at the University of California, Davis, examined 35 dog breeds and found vulnerability from neutering, and the age at which they are neutered, varies greatly depending on the breed. View the source article

More than one cognition: A call for change in the field of comparative psychology

Researchers argue that cognitive studies in comparative psychology often wrongly take an anthropocentric approach, resulting in an over-valuation of human-like abilities and the assumption that cognitive skills cluster in animals as they do in humans. The authors advocate for philosophical and procedural changes to the discipline that would lead to a better understanding of animal minds and the evolution of multiple forms of cognition.

Oil spill clean-up gets doggone hairy

Researchers have found that dog fur and human hair products -- recycled from salon wastes and dog groomers -- can be just as good as synthetic fabrics at cleaning up crude oil spills on hard land surfaces like highway roads, pavement, and sealed concrete floors. View the source article

Care for cats? So did people along the Silk Road more than 1,000 years ago

Common domestic cats, as we know them today, might have accompanied Kazakh pastoralists as pets more than 1,000 years ago. This is indicated by new analyses done on an almost complete cat skeleton found during an excavation along the former Silk Road in southern Kazakhstan. An international research team has reconstructed the cat's life, revealing astonishing insights into the relationship between humans and pets at the time. View the source article

Owner behavior affects effort and accuracy in dogs' communications

Researchers have found that dogs adapt their communicative strategies to their environment and that owner behavior influences communicative effort and success. Experimental results found no evidence that dogs rely on communication history or follow the principle of least effort and suggest that owner behavior has a bigger impact on canine communication than previously thought.

Grassroots dog vaccinations can help stop rabies, but not alone

While scientists are trying to find a vaccine for COVID-19, the rabies virus continues to kill 59,000 people every year. But unlike COVID, a vaccine has existed for more than a century. Vaccinating dogs can stop the spread to humans, but systemic challenges make that easier said that done. In a new study, scientists where grassroots campaigns to stop rabies work -- and where they need to be coupled with large-scale efforts. View the source article

How old is your dog in human years? New method better than 'multiply by 7'

How old is your tail-wagging bundle of joy in human years? According to the well-known ''rule of paw,'' one dog year is the equivalent of 7 years. Now scientists say it's wrong. Dogs are much older than we think, and researchers devised a more accurate formula to calculate a dog's age based on the chemical changes in the DNA as organisms grow old. View the source article

Dangerous tick-borne bacterium extremely rare in New Jersey

There's some good news in New Jersey about a potentially deadly tick-borne bacterium. Researchers examined more than 3,000 ticks in the Garden State and found only one carrying Rickettsia rickettsii, the bacterium that causes Rocky Mountain spotted fever. But cases of tick-borne spotted fevers have increased east of the Mississippi River, and more research is needed to understand why. View the source article

Yes, your dog wants to rescue you

Imagine you're a dog. Your owner is trapped in a box and is crying out for help. Are you aware of his despair? If so, can you set him free? And what's more, do you really want to? That's what researchers wanted to know when they gave dogs the chance to rescue their owners. View the source article

Fearful Great Danes provide new insights to genetic causes of fear

Researchers have identified a new genomic region and anxiety-related candidate genes associated with fearfulness in dogs. Findings support their hypothesis that fearfulness and anxiety are hereditary traits in dogs, and there may be shared factors underlying anxiety in both humans and dogs. View the source article

Why cats have more lives than dogs when it comes to snakebite

Cats are twice as likely to survive a venomous snakebite than dogs, and the reasons behind this strange phenomenon have just been revealed. The research team compared the effects of snake venoms on the blood clotting agents in dogs and cats, hoping to help save the lives of our furry friends. View the source article

Saving livestock by thinking like a predator

Humans have struggled to reduce the loss of livestock to carnivores for thousands of years, and yet, solutions remain elusive. According to a new study, solving this ancient puzzle requires going back to Ecology 101. Simply put, getting in the mind of predators -- considering how they hunt, how their prey behaves and the landscape -- will help wildlife managers discourage wild carnivores from preying on valuable livestock.

Dogs can detect traces of gasoline down to one billionth of a teaspoon

Trained dogs can detect fire accelerants such as gasoline in quantities as small as one billionth of a teaspoon, according to new research by chemists. The study provides the lowest estimate of the limit of sensitivity of dogs' noses and has implications for arson investigations. View the source article

The movie 'Jurassic Park' got it wrong: Raptors don't hunt in packs

A new analysis of raptor teeth shows that raptorial dinosaurs likely did not hunt in big, coordinated packs like dogs. Though widely accepted, evidence for this behavior is relatively weak. Recently, scientists have proposed a different model for behavior in raptors that is thought to be more like Komodo dragons, in which individuals may attack the same animal but cooperation is limited.
