As the availability of COVID-19 tests dwindle across Canada, another option to detect the virus in the form of a furry friend may be the next best thing.
Multiple studies show that dogs can be more effective, faster and potentially less expensive than the current tests on the market.
The research has grown since 2020, with University of California Santa Barbara professor Tommy Dickey finding the collective research shows trained scent dogs are “as effective and often more effective” than both the rapid antigen tests many people keep in their homes, and even the PCR tests deployed at clinics and hospitals.
But even with studies showing their effectiveness, COVID-19-detecting dogs are deployed only in certain jurisdictions in various countries.
One such place is the Canines for Care program at Vancouver Coastal Health (VCH), which started looking into the possibility of training dogs to detect COVID-19 in early 2021.
Dr. Marthe Charles, division head of medical microbiology and infection prevention and control at VCH, said the idea stemmed from the early reliance on laboratory testing.
“I think there was a will from public health at the time and also from the various levels of government to try to find a way that was fast, accurate and non-invasive to be able to detect and train as many people as possible,” Charles told Global News in an interview.
Three dogs — two Labrador retrievers and an English springer spaniel — were brought in for training. The dogs were exposed to items such as masks that were worn by patients either negative or positive for the virus. This trained the dogs to recognize what is and is not COVID-19.
Charles said the dogs were trained since being puppies to associate the scent of COVID-19 with food and were rewarded each time they correctly detected a positive case of the virus.
“So from early on in their lives, they’ve associated the scent of a case of COVID to a rewarding scent,” she explained.
This reward method is not just used by VCM. It was also used with a group of dogs sourced in early 2021 for a French study, trained at detection using toys — usually tennis balls — as rewards.
Dr. Carla Simon, owner of Hunter’s Heart Scent Detection Canines in Calgary, said this method of training dogs is common. By using rewards, it can help motivate them to find the scent.
“We would pair, let’s say, the sweat samples with COVID, with their reward, and they notice that every time they find their reward, there’s that special smell,” she explained. “We just have to make it rewarding for the dog.”
She added, however, that the dog chooses the reward so trainers can ensure the canines “show up every day and want to do their job.”
Earlier this month, Dickey along with Heather Junqueira of BioScent, Inc. gathered several peer-reviewed studies into a review that was published in the Journal of Osteopathic Medicine. Dickey said the number of peer-reviewed studies over the past few years went from four to 29, incorporating the work of more than 400 scientists from more than 30 countries and 31,000 samples.
The review noted the effectiveness of dogs’ ability to detect COVID-19 comes down to their noses.
“The nose is not like humans,” Simon said. “It’s massively different, orders of magnitude different, and they can detect things without us being able to smell them.”
Humans have about five to six million olfactory receptors in their noses, while dogs have hundreds of millions. One-third of their brain is devoted to the interpretation of smell — something only five per cent of a human’s brain is committed to, according to Dickey’s review.
The study found dogs’ noses may even be able to detect pre-symptomatic COVID-19 cases, or even those who will develop symptoms later.
Dickey told us in an interview that this could help limit or stop the virus from spreading.
“The longer the wait is between your test and your result, that’s a latent period,” he said. “During that time you’re running around spreading COVID and you don’t know it. The dogs with a direct sniff will be done in seconds.”
Many of the studies conducted, including the work at VCH through the Canine for Care program, have shown dogs’ ability to detect the disease correctly with a success rate of more than 90 per cent. Additionally, the studies also showed a high speed at which the dogs could identify cases. In one study in Thailand, researchers reported the dogs had gone through thousands of samples in just a few weeks.
“The dogs take only one to two seconds to detect the virus per sample. Once they detect a patient, they will sit down,” said Chulalongkorn University professor Kaywalee Chatdarong, who led the 2021 project. “This takes only one to two seconds. Within one minute, they can manage to go through 60 samples.”
Even though the research suggested deploying scent-detection dogs could also be less expensive than rapid or PCR tests, Charles cautioned the logistics that go into training the dog is where it becomes “more prohibitive.”
In VCH’s case, training of the dogs included the medical microbiology lab to provide samples for use, working with infection prevention teams and control nurses, and if a dog identifies an area of concern, cleaning services may need to be utilized. And when it comes to rolling out testing using the dogs, enough staffing is needed for mass screening.
Despite this, while Charles says deploying the dogs widely could be difficult due to staffing and training, they are still one of several tools that can be used in COVID-19 detection.
“I think the way to see those dogs from my perspective is really like another tool in the toolbox and trying to prevent further transmission of pathogen of concern,” she said.
Dickey and Junqueira say dogs should have a place in “serious diagnostic methodology” including in helping should the world face a future pandemic.
Grandfather Fears Dog Wouldn’t Recognize Him After a Year Apart, but Excited Pup Rushes Towards Him, Melting Hearts with Reunion Joy.
One of the best things in life, and I recognize you will agree with me on this, is coming home to a canine bounding up to invite you after a long day at work. One of the many reasons we appreciate our canine friends a lot is the absolute, unrestrained pleasure and thrill of your existence.
Will a dog eventually forget about you after years apart? Fortunately, as evidenced by this story, they will not!
After a year of being away, a blind and deaf puppy saw her grandfather, the owner’s dad, and despite the owner’s fears of a broken bond, the puppy went into ecstatic overdrive.

On TikTok, a sweet video clip of a man called Steve reconciling with his daughter’s dog, Bitsy, went viral. Hayden Kristal’s canine is unique since she was born deaf and blind, but Hayden did not allow that stop her from adopting the puppy when she was just 5 weeks old.
At first, they were stressed over how the puppy would certainly deal with life, but she rapidly proved they had nothing to be afraid. Hayden said, “She has been her own lady because day one. The first thing she did when I brought her residence was to make a beeline for the food dish, creep right into it and eat till she passed out.”
Five years later, she is still a stunning, vivacious canine that still enjoys hanging out with her mother, a few brother or sisters, and other family members. Bitsy and her mom were forced to live besides their relatives last year after COVID limitations were put in place to guarantee their security. As a result, the puppy and the dad would be separated for an entire year.
According to the caption, her dad was concerned that Bitsy will forget him after a year apart, but that was not the situation because the canine knew her grandpa’s embrace right away. She was licking at the man’s face while leaping up and down. Steve was as delighted to see the puppy as she was to see him, and a smile never left his face.
” As quickly as I obtained within scent range, she completely lost her mind with joy. So did I,” Steve wrote on Facebook. “Once again Bitsy proved that the abilities she has are far more impressive than the ones she’s missing. What a really incredible and fantastic soul. Perhaps you can tell from this video just how much we love each other.”
Hayley’s father spends as much time as feasible with his granddog because he loves the animal more than he could have ever pictured. He is her biggest supporter and fan, according to Hayden.
” He will inform anybody who will listen regarding what an amazing canine she is and how much he enjoys her. He does the normal grandfather things of spoiling her with treats and toys and she loves to simply hang out near him.”
Bitsy and her mother have taken several trips across the country, hiking, canoeing, riding the subway, and also skating. “Bitsy is the sweetest, friendliest, most caring, and faithful dog in the world,” Hayden said. “She is bold and sexy and she enjoys adventure!” She likewise appears to have a love of ribs and BBQ sauce.
“She’s taught me a lot regarding love, life, and swallowing whole rotisserie hens before an authority figure can wrench the bird shrapnel from your thieving hyena jaws,” she said in her Instagram article.
It is wonderful that the family can currently be back with each other. Although dogs can see and listen to, Pet Place claims that their primary sense of perception is smell. Because of this, dogs without hearing will depend on touch and smell to inform them when a person is nearby, which will create them to come to be much more connected to their human buddies than formerly. For stability and comfort, they significantly rely on predictable routines, so maintaining things like bedding and feeding bowls in the exact same area is useful.
The big query at this moment is just how much a canine can recall.
For all those years, Hachi waited for his owner at the railway terminal, but existed more to it than simply habit and loyalty?
Swifto insists that, unlike humans, canines have a unique method for keeping, processing, and recalling memories.
They possibly don’t recall all the meals they have actually had because they have bad short-term memory, which is why they maintain asking for even more food. They have an associative memory, which implies that rather than having true memories, they remember experiences based upon associations. As a result, Bitsy most likely recognized the grandpa by his voice and fragrance, which served as a reminder of who he was.
You don’t need to be worried that your dog will soon forget you. And if you come across a particular puppy because of this, there are lots of solutions offered, so put your worry aside and begin cuddling puppies! However, adopt correctly and guarantee that you can offer your dogs.
We send out Bitsy and her household our hottest desires and will keep up with their travels and joie de vivre.
