Canine eggheads enjoy playing with toys and retrieving objects.
“Gifted” dogs, who have a rare talent for learning lots of words for objects easily, also turn out to be more playful than other dogs, a new study finds.
Prior research in humans has shown a link between playfulness and problem-solving abilities, so animal behavior researchers from Eötvös Loránd University in Budapest, Hungary, wondered if the same was true for rollicking pups.
What is a gifted dog? In the new study, it was Border collies who had proven in prior research that they were able to learn as many as 12 new words per week and then retain them for months.
To take a closer look at the possible association between giftedness and playfulness in dogs, Claudia Fugazza, a researcher in the university’s department of ethology (the study of animal behavior), and her colleagues asked the owners of 165 Border collies to fill out dog personality questionnaires. Twenty-one of the dogs were gifted and the other 114 were just randomly selected with no testing for word learning ability.
The surveys assessed the personality of the animals in five categories:
- Fearfulness, including fear of people, nonsocial fear, fear of dogs, fear of handling.
- Aggression toward people, including general aggression and aggression in certain situations.
- Activity/Excitability, including excitability, playfulness, active engagement and companionability.
- Responsiveness, such as trainability and controllability.
- Aggression toward animals, including aggression toward dogs, prey drive and dominance over other dogs.
For the evaluation of playfulness the owners were asked to rate their dogs in three areas:
- Dog gets bored in play quickly.
- Dog enjoys playing with toys.
- Dog retrieves objects, such as balls, toys and sticks.
The researchers focused solely on Border collies because earlier experiments found that the breed is more likely to be good at learning new words compared to others.
After collecting the survey responses, the researchers then compared the responses from owners of gifted dogs to those from the owners of dogs who had not been identified as gifted.
Playfulness was the only personality trait that was consistently different between the two groups.
It’s not clear from the study whether it’s the playfulness that helps the dogs learn more words, or whether the extra playful ones ended up with more opportunities to learn, said Fugazza, the study’s lead author, said in an email. That’s because gifted dogs tend to learn words for objects when their owners are playing with them.
Are playful dogs smarter?
Not exactly.
“Intelligence is the result of diverse cognitive traits that allow individuals to flexibly solve different types of problems,” Fugazza explained. “Giftedness refers to an extremely good capacity in the case of a specific skill.”
So, maybe gifted dogs are like people who score high on the verbal part of the SATs.
If your pup doesn’t learn words easily, it doesn’t mean it’s a dumb dog. Adam Boyko, an expert in canine genomics, reassures owners that canine intelligence is more than that.
“Both dogs and wolves are playful when they are puppies, but dogs really evolved to living in the human environment and to responding to social cues,” said Boyko, a specialist in the genetics of behavior and an associate professor at the Cornell University College of Veterinary Medicine. “It’s not surprising that the more playful ones exhibit better learning in the domain of learning human words. And it’s not surprising that Border collies, who are bred to respond to human cues, show the propensity to learn words more than other breeds.”
Other breeds of dogs might show intelligence in other ways, Boyko said. For example, wolves are very intelligent although they don’t typically pick up on human cues.
“But they can figure out how to escape,” said Boyko. “Where dogs would look for a person to help, wolves would see how humans did a latch and lock and then the wolves would do it themselves to get out.”
Boyko would like to take the study a step further and look at the genetics of the gifted dogs.
“This is a tantalizing correlation that might be meaningful if you are trying to build better service dogs,” he said.
One thing that can’t be determined from the study is whether the playfulness trait spurred owners to interact more with their dogs and thus teach them more words, said Dr. Nicholas Dodman, a professor emeritus at the Cummings School of Veterinary Medicine at Tufts University, CEO and president of the Center for Canine Behavior Studies and the author of “Pets on the Couch: Neurotic Dogs, Compulsive Cats, Anxious Birds and the New Science of Animal Psychiatry.”
Dodman said the study is interesting but needs to be replicated in a larger number of dogs.
“I would also like to see it done in a different breed,” he said.
The new findings might help people who want to buy or adopt a puppy. It suggests that playfulness might be a good attribute to consider.
“The playful ones might be more likely to interact with a person, assimilate words more easily and be more intelligent,” said Dodman.
Can dogs really detect Covid-19 infections faster and more accurately than a lateral flow test?
Results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner – so no need to swab your throat or nose
Dogs can detect Covid-19 faster and more accurately than a PCR test, a new study shows.
Researchers looked at the ability of canines to recognise the virus and its variants, even when they are obscured by other viruses, like those from common colds and flu.
More than 400 scientists from over 30 countries contributed to the study as well as 147 scent dogs, according to the findings published in the Journal of Osteopathic Medicine.
After analysing many studies covering both field and clinical experiments, Professor Dickey and Junqueira found that dogs who are trained to sniff out scents are “as effective and often more effective” than antigen tests.
A total of 53 dogs were trained to sniff out Covid scents, while 37 were not and scientists found that the dogs that were not trained were in some cases “slightly superior” to those that were pre-trained.
“The previously untrained dogs have the advantage that they are not as prone to indicating on scents other than the Covid–19 associated scent,” the paper said.
The results indicated that not only can dogs detect Covid faster, but they can also do so in a non-intrusive manner. This means you won’t need to put a swab in your throat or nose.
How can dogs detect the virus?
This essentially comes down to the dog’s highly evolved nose with its ability to sense out smells quicker.
Dogs possess up to 300 million olfactory receptors in their noses, compared to about six million in humans. And the part of a dog’s brain that is devoted to analysing smells is about “40 times greater” than humans. Canines also have ‘neophilia’, which means they are attracted to new and interesting odours
And so, with all these enhancements, dogs can detect very low concentrations of odours associated with Covid infections.
“They can detect the equivalent of one drop of an odorous substance in 10.5 Olympic-sized swimming pools,” Professor Dickey said. “For perspective, this is about three orders of magnitude better than with scientific instrumentation.”
Scientists also found that in some cases, the animals were also able to detect the virus in pre-symptomatic and asymptomatic patients, “whose viral load was too low for conventional tests to work.”
Professor Dickey has said that dogs can also differentiate Covid and its different variants in the presence of other respiratory viruses. This included the common cold or flu.
“They’re much more effective. In fact, one of the authors that we quote in the paper commented that the RT-PCR test is not the gold standard anymore. It’s the dog. And they’re so quick,” he added. “They can give you the yes or no within seconds if they’re directly smelling you.”
How was the study conducted to see if dogs can really detect Covid-19?
In some studies, the dogs gave a person a quick sniff, sitting down to see if the person has Covid. In another study, the dog was given a sweat sample to smell for a few minutes.
The press release has said that scent dogs, such as beagles, basset hounds and coonhounds are the ideal candidates for sniffing out the virus, given their “natural tendencies to rely on odours to relate to the world.”
But the studies which the researchers analysed showed a variety of dogs were up for the challenge and were able to sniff out the Covid odour. With a few weeks of training, puppies, older dogs, purebred and mixed breeds, both male and female were able to sniff such odours out and “all performed admirably,” the Eureka Alert press release said.
Although there has been success with dogs detecting such viruses, researchers believe there are still many challenges with using dogs for medical diagnoses.
“There’s quite a bit of research, but it’s still considered by many as a kind of a curiosity,” said Professor Dickey.
In conclusion, Professor Dickey and Junqueira said after reviewing the studies, believe that scent dogs deserve “their place as a serious diagnostic methodology that could be particularly useful during future pandemics, potentially as part of rapid routine health screenings in public spaces.”
“Perhaps, most importantly, we argue that the impressive international quality and quantity of COVID scent dog research described in our paper for the first time, demonstrates that medical scent dogs are finally ready for a host of mainstream medical applications,” they added.
