Life has a beautiful way of surprising us, and sometimes, those surprises come in the form of a furry, four-legged companion. Meet Johanna Carrington, a remarkable centenarian who, despite a life filled with challenges, has always carried a deep love for dogs.
Johanna’s journey began in war-torn Germany, where owning a dog was a distant dream. She and her late husband once shared their home with eight Pekingese dogs, a testament to their shared love for these loyal creatures. However, when her beloved dog Rocky passed away, Johanna was left feeling alone in her house, yearning for a furry friend.
One might think that, at the age of 100, adopting another dog could be a challenge. Johanna was uncertain if the shelter would allow someone of her age to adopt. Fortunately, a caring neighbor who supports Muttville Senior Dog Rescue in San Francisco suggested that this organization might have the perfect solution.
Muttville Senior Dog Rescue recognized that Johanna Carrington and a senior dog would be an ideal match. After careful consideration, Johanna adopted Gnocchi, a charming 11-year-old Chihuahua, whom she lovingly renamed Gucci.
Gucci’s life had a rocky start; he was rescued from a hoarding situation where his previous owner had 22 dogs. Being the only pampered pooch in his new home brought him immense joy. Johanna’s caregiver, Eddie Martinez, and her daughter, Debbie Carrington, made a heartfelt commitment to ensure that Gucci’s golden years would be filled with love and care.
The moment Gucci entered his new home, he seemed to recognize that he belonged there. Johanna recalled the heartwarming first encounter, saying, “He approached the home as though he’d been here before. It was incredible. When he spotted me seated in my chair, he leapt up and perched on my lap. He made himself extremely at ease. Right away, he was just our kid.”
Now, Gucci enjoys a life fit for a pampered pup. He has “oodles and oodles” of toys to play fetch with, daily back massages while watching TV with his new mom, and even the privilege of burrowing under the covers in bed for extra comfort.
Debbie Carrington, Johanna’s daughter, shared how Gucci’s arrival transformed their home, saying, “It was sort of sad here after she lost her other dog. It was silent and melancholy until Gucci came in and brought excitement into the house. Laughing at him running around and doing silly things, and then him resting on her lap with her when she’s in her chair or bed, it’s just making her very happy.”
The heartwarming bond between Johanna and Gucci is a testament to the joy and companionship that animals bring into our lives, regardless of age. In fact, scientific research supports the positive impact of pet ownership on emotional and social well-being, particularly in older individuals.
As Johanna approaches her 101st birthday in December, she and Gucci plan to celebrate this special milestone together. For Johanna, dogs have played a significant role in her long and healthy life, proving that the love between a human and their furry friend knows no age limits.
In a world that often seems fast-paced and hectic, the story of Johanna and Gucci reminds us of the simple yet profound happiness that animals can bring into our homes and hearts.
Dogs have nose for COVID-19, studies show. Why aren’t they used for testing?
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.
