As a pet owner, you may gradually learn to interpret each wag, meow, and bark, but the idea of knowing precisely what your pet is saying is still fascinating. Recent studies show that scientists are now using artificial intelligence (AI) to decode animal communication.
AI as a Tool to Decode Pet Communication
Daniel Mills, a professor of veterinary behavioral medicine at the University of Lincoln in England, emphasized AI’s potential to interpret pets’ communications, noting that it could provide valuable insights into their intentions, The Guardian reported.
This study builds on earlier research in Science Direct showing that cats use 276 facial expressions when interacting with each other. Brittany Florkiewicz of Lyon College noted that cats express themselves differently with humans, adding to the challenge of interpretation—something AI research could help unravel.
How AI Learns to Read Animal Emotions
Mills suggests that training AI to recognize specific traits, like ear position, could be key to identifying certain emotions. Letting AI create its own criteria for expressions could offer new insights and distinctions.
Mills and his team use AI to study the facial expressions of cats, dogs, and horses from online videos to identify emotions. The technology could also improve animal welfare by detecting pain in cows during milking and aiding routine health checks.
Dr. Jake Johnson, a cardiology resident at North Carolina State University’s College of Veterinary Medicine, recently published an article in Frontiers in Veterinary Science. In it, he shares his research findings and offers advice on preventing future accidents involving pets.
What Motivated You To Pursue a Career in Research?
I first encountered the One Health Initiative during my undergraduate studies, and it fundamentally shaped my perspective on the power of collaborative science. This approach emphasizes the connection between veterinary medicine, human health, environmental sciences, and other fields, all working together to improve collective well-being.
What struck me most was the deep interdependence of our health challenges—diseases don’t recognize the boundaries between species or ecosystems. I came to see that discoveries in veterinary medicine often extend far beyond animals, carrying insights that benefit broader scientific and medical communities.
At the core, I believe knowledge holds the greatest value when we share it. Research offers me the chance to contribute to that exchange of ideas, creating ripple effects that reach well beyond any single case I could address in practice.
Could you Share Details About the Research You’re Currently Involved In?
During my cardiology residency and beyond, I focus my research on closing the gap between advanced cardiology knowledge and its practical use in clinics, with a strong emphasis on education.
My aim is to make specialized cardiac training more accessible to veterinary students and clinicians who may have limited exposure to this field. My prior work includes a case report on a cat with an atypical presentation of heart failure, where imaging techniques were key in shaping different clinical approaches.
How Do Veterinarians Investigate Cocaine poisoning In Animals?
Most studies on this subject take place in controlled laboratory settings. Because data in dogs is scarce, veterinary research often relies on information derived from human medicine. However, experimental models frequently fail to reflect real-world clinical situations, so only a small number of case reports are available.
Another difficulty is that pet owners may be unaware of what their dog ingested, or they may hesitate to disclose it. This creates a noticeable gap between controlled research conditions and the unpredictable realities of clinical practice.
What Symptoms Did the Chihuahua Show, and How Was The Diagnosis Made?
The dog was first seen at the referring clinic for collapse episodes and a markedly low heart rate. Because we suspected illicit substance ingestion, we ran a point-of-care urine drug screen that tested positive for cocaine, later confirmed by an external laboratory test.
How can Pet Owners Reduce The Risk of Their Animals Accidentally Consuming These Substances?
Dogs are instinctive scavengers and will often investigate objects they find on the ground, so extra caution is needed during walks. Owners can reduce the risk of ingestion by keeping their dog leashed, monitoring closely for attempts to pick up or eat unfamiliar items, and, if needed, using a basket muzzle.
Teaching commands like “leave it” and “drop it” can be critical in preventing harm if they come across something dangerous. If you suspect your dog has been exposed to something harmful or notice unusual behavior, take them to a veterinarian immediately—acting quickly can save their life.
How Do You See The Significance of Your Research?
Case reports play an essential role in veterinary medicine by documenting real-life cases. They highlight clinical situations that broader studies may overlook, record uncommon presentations for future use, and contribute to our shared knowledge of rare conditions—ultimately enhancing emergency readiness and guiding treatment strategies.
What Are Common Misconceptions In This research, and How Would You Address Them?
A common misunderstanding in toxicology research—especially with illicit substances—is that veterinarians will judge or report owners if they admit their pet may have ingested drugs.
This fear often stops owners from sharing vital details that could save their pet’s life. When owners share what was consumed, when, and how much, vets can give the most effective treatment and monitor closely for complications. The priority is always getting the pet urgent care, not placing blame.
What Future Research Areas Would you Like To See Explored?
Veterinary medicine has advanced rapidly, with procedures like open-heart surgery, kidney transplants, dialysis, and bronchial stents now possible—treatments once thought unattainable. The real challenge, however, is making these life-saving options widely accessible.
Future research should focus on breaking down barriers to advanced care. This includes developing simplified imaging techniques for standard equipment, cost-effective screening tools, and educational strategies that translate specialized knowledge into practical applications for everyday practice.
It’s also important to address the financial side of care through studies on lower-cost treatment alternatives, training general practitioners in basic specialty procedures, and expanding telemedicine for specialist input.
Ultimately, the goal is to make advanced veterinary care more equitable, so pets in rural clinics can receive the same life-saving treatments as those in urban specialty hospitals. Only then can these breakthroughs truly maximize their impact on animal welfare.
In What ways Has Open Science Expanded the Reach and Influence of Your Research?
Knowledge is only valuable when it’s accessible. Removing barriers allows information to reach more people. I aim to equip peers with the tools to apply aspects of cardiology in practice, even with limited resources.

Your dog tilts its head when you cry, paces when you’re anxious, and shows up beside you during your toughest times. Coincidence? Hardly.
After thousands of years of co-evolution, dogs have developed remarkable abilities to read our voices, faces, and even brain chemistry. Specialized areas in their brains respond to human speech, and making eye contact triggers a surge of oxytocin—the “love hormone”—wiring them to sense our emotions.
This emotional awareness is rooted deep in their neurology. Like humans, dogs have specific brain regions attuned to vocal cues. Brain imaging study show that their temporal cortex lights up when they hear voices, especially emotionally charged ones. Sounds like laughter, crying, or yelling trigger activity not only in their auditory cortex but also in the amygdala, the brain’s emotional center.
Dogs are also surprisingly good at reading human faces. When they see images of people, their brains show heightened activity—especially when the face is familiar. One study found that a known human face activates both the emotional and reward centers in a dog’s brain, suggesting they interpret our expressions not in words, but through emotions.
But dogs don’t just notice your emotions—they can absorb them too. This phenomenon, known as emotional contagion, is a basic form of empathy where one being reflects the emotional state of another. A 2019 study showed that some dogs and their humans had synchronized heart rates during moments of stress, their heartbeats aligning in real time.
This kind of empathy doesn’t rely on complex thought—it’s more instinctive, shaped by close relationships. Emotional bonding and learned responses likely prompt your dog to yawn when you do or whine when you’re upset—not any ability to literally read your mind.
The Power Of Oxytocin
One of the most fascinating findings in the human-dog bond is the chemical connection we share. When you and your dog engage in gentle eye contact, both of your oxytocin levels—the so-called “love hormone”—rise.
In a study, owners who spent more time gazing into their dogs’ eyes had a noticeable boost in oxytocin afterward—and so did their dogs. This mutual oxytocin surge strengthens the emotional bond between you, similar to the bonding that happens between parents and infants.
Remarkably, this effect appears to be exclusive to domesticated dogs. Even hand-raised wolves didn’t show the same hormonal response to human eye contact. As dogs evolved alongside humans, they developed this oxytocin feedback loop to forge emotional ties with us. So when your dog locks eyes with you, it’s not just adorable—it’s chemically connecting you both.
Dogs impressively read our body language and facial expressions, in addition to making eye contact. Studies show they can even tell the difference between a smiling face and an angry one—just from photographs.
Dogs have a subtle preference for using the right side of their brain when reading emotional signals, which makes them more likely to focus on the left side of a person’s face—similar to how humans and other primates interpret expressions.
To understand how you’re feeling, dogs draw on several senses. A light, upbeat “Good boy!” paired with a calm stance gives off a very different vibe than a harsh tone and stiff posture. Impressively, dogs can even smell emotions. In a 2018 study, dogs exposed to sweat from frightened people showed higher stress levels than those that smelled sweat from happy individuals. In short, your stress has a scent that unsettles your dog, while your calm happiness can help soothe them.
Born To Bond With Humans
What made dogs so sensitive to human emotions? The key lies in their shared evolutionary path with us. Although their brains are smaller than those of their wild wolf ancestors, domestication may have rewired dogs’ brains to better handle social and emotional cues.
Insights come from a Russian experiment with foxes, where those selectively bred for tameness developed more gray matter in brain areas tied to emotion and reward. This challenges the belief that domestication dulls intelligence—on the contrary, selecting for sociability can strengthen neural pathways involved in bonding.
Over thousands of years living alongside people, dogs have developed brain systems highly attuned to human social signals. Despite having smaller brains than wolves, dogs’ brains may be specially adapted for forming close emotional ties with us.
Dogs likely don’t understand the reasons behind your emotions or grasp that you have separate thoughts. Instead, they’re remarkably skilled at sensing what you’re feeling and responding appropriately.
So while they might not truly “read minds,” dogs connect with us emotionally through behavior and expression. In today’s fast-paced world, that kind of intuitive connection goes beyond mere cuteness—it’s a powerful, evolved form of empathy that shows how friendship can cross the boundaries between species, even without words.

The greatest sorrow of owning a pet is their limited lifespan. Fortunately, scientists are addressing this issue by developing a new cancer vaccine for dogs, which significantly increases their survival rates against certain types of the disease.
Similar to humans, cancer is prevalent in dogs, particularly in larger and older breeds. However, while humans have numerous treatment options available, there are limited choices for dogs battling cancer. Radiation and chemotherapy are frequently used, but their varying success rates, along with associated costs and availability issues, often result in premature loss of canine companions.
Yale Scientists Adapt Human Cancer Treatments for Dual Benefits in Dogs and Humans
For their recent research, scientists at Yale modified existing human cancer therapies to develop a novel version with potential benefits for both humans and dogs, as certain cancers share characteristics across species. They focused on monoclonal antibodies, a burgeoning treatment method where patients are administered protein infusions that target EGFR and HER2, two proteins overexpressed in various cancers such as colorectal or breast cancer.
However, a common issue arises as patients often develop resistance to these antibodies, diminishing the treatment’s effectiveness over time. To address this challenge, the new study aimed to create polyclonal antibodies instead. These antibodies, derived from multiple immune cells, target various regions of EGFR/HER2.
After discovering a compound with such capabilities, the researchers conducted tests on mice followed by trials involving dogs. The results were highly promising, leading to multiple clinical trials over the past eight years, encompassing more than 300 dogs. The treatment effectively targeted tumors and disrupted the pathways facilitating their growth.
According to the researchers, their canine cancer vaccine has nearly doubled the 12-month survival rate for dogs afflicted with certain types of cancer. For instance, dogs diagnosed with osteosarcoma typically have a 35% chance of surviving one year after diagnosis with conventional treatments like chemotherapy. However, the cancer vaccine increased this rate to 60%.
Living Proof of the Cancer Vaccine’s Success
Hunter, an 11-year-old golden retriever, serves as living evidence of the vaccine’s efficacy. Initially diagnosed with osteosarcoma in his front left leg in 2022, Hunter underwent amputation, chemotherapy, and received the new cancer vaccine. Two years later, he continues to lead a happy and active life.
Currently, the team is preparing for additional research to explore the potential of administering the cancer vaccine to healthy dogs as a preventive measure against cancer or to intervene at earlier stages of its development. Any efforts aimed at extending the lives of our beloved pets are considered a success by the team.
The findings from the clinical trial research were published in the journal Translational Oncology. Watch Hunter’s inspiring story in the accompanying video.
‘Dogs suffer greatly from their cancers.’ So a Yale researcher developed a vaccine.
