Dogs and humans are more alike than we thought, study finds - Texas A&M Stories

Skyler: Hey there, dog lovers — welcome to Frosty the Dog, the show that celebrates everything wonderful, weird, and completely heartwarming about our best friends. I'm Skyler, your host, and I am so glad you're here. This show is named for a very special boy — Frosty — the goodest, most beloved dog, the one who inspired all of this, and honestly the one I think about every single time I sit down to tell these stories. We're going to be celebrating Frosty and dogs just like him all episode long. Before we dive in, a huge thank you to our sponsors — starting, as always, with our primary sponsor and namesake, Frosty — the best boy in the whole world. We're also brought to you by Ada, who helps clients integrate A I into their workflows; Ago Consulting — that's "Ahh-Go" — silicon development consulting from A I to SoC; and Zen Semiconductor, an umbrella company with a portfolio of companies across the silicon industry. These are the good people keeping this show going, and we love them for it. Okay — today we have got some genuinely mind-blowing dog stories for you. We're talking about how dogs and humans are more alike than anyone realized, a look at science that could actually help dogs — and us — live longer, and some fascinating new thinking about breeds and behavior. Plus, there's a college that is doing something so clever with dogs that I wish it had existed when I was in school. Let's go. Skyler: Alright, thread one — Dog Science and Discovery — and friends, this one is going to make you look at your dog a little differently. In a good way. In a "wait, are you basically a furry little person?" kind of way. Researchers at Texas A&M University have been digging into the biological and behavioral overlap between dogs and humans, and what they're finding is genuinely surprising. The short version? Dogs and humans are more alike than we thought. And I mean that in a deep, scientific sense — not just the "we both love naps and snacks" sense, though, I mean, Frosty would absolutely agree on that front too. Skyler: So here's what's so compelling about this. Dogs are one of the only animals on the planet that have been living alongside humans for tens of thousands of years — we're talking somewhere in the range of fifteen thousand years or more of shared history, shared environments, shared diseases even. And that long cohabitation has left real marks, biologically. Dogs and humans have been shaped by each other. We've influenced each other's evolution in ways scientists are only now starting to fully appreciate. And when researchers look closely at things like how dogs' bodies respond to stress, how they age, how they get sick — they find these remarkable parallels to human biology. Skyler: Texas A&M is actually home to one of the most ambitious dog health research programs in the world, and a big part of what makes their work so exciting is that they're not just studying dogs for the sake of dogs — though honestly that would be reason enough, right, Frosty? — they're studying dogs because understanding dogs teaches us something profound about ourselves. The diseases dogs get, the way they age, the way their bodies work — these things mirror human health in ways that could open up new doors in medicine. Skyler: And think about that for a second. Frosty, our very own best boy, and every dog you've ever loved — they're not just companions. They're kind of our biological cousins in this really unexpected way. Dogs get cancer. Dogs get diabetes. Dogs experience anxiety and cognitive decline. And because they go through these things on a shorter timeline than we do — dogs age faster than humans — they actually give scientists a faster window into processes that take decades to study in people. That's remarkable. That's Frosty-level remarkable. Skyler: What I love most about this research is what it says about the relationship. It's not just emotional, this bond between dogs and humans. It's written into our biology. We changed each other. We made each other. And now, understanding one might help us save the other. If that doesn't make you want to go hug your dog right now, I don't know what will. Skyler: Okay, thread two — Dogs and Humans — and this one builds beautifully on what we just talked about, because it takes that science and turns it into something with real stakes. Real lives. Possibly longer ones. CBS News and 60 Minutes did a deep dive recently into research that is essentially asking: what if studying dogs could help both dogs and humans live longer, healthier lives? And the answer, it turns out, might be yes. Genuinely, scientifically, yes. Skyler: The centerpiece of this conversation is something called the Dog Aging Project. Now, this is a large-scale, long-term scientific study — one of the biggest of its kind — that is following tens of thousands of dogs across the United States over many years, tracking their health, their habits, their environments, and their genetics. The goal is to understand what makes some dogs age well and live long, and what puts other dogs at risk. And the reason it matters beyond dogs — beyond our beloved Frosty and every dog like him — is that aging in dogs and aging in humans share a lot of the same underlying biology. Skyler: Scientists involved in this work have pointed out that dogs are actually one of the best models we have for studying aging. They live in our homes. They breathe our air. They eat food that isn't so different from ours in a lot of cases. They experience stress. They form emotional bonds. And they develop many of the same age-related conditions we do — heart disease, cancer, cognitive decline — but they do it in a compressed timeframe. A dog might go through the equivalent of a human's entire aging process in ten to fifteen years. That means researchers can actually watch it happen, study it in real time, in a way that's just not possible with humans. Skyler: And here's where the bond part really comes in, because the Dog Aging Project isn't just scientists studying dogs in a lab. It's dog owners — regular people, families, kids, folks just like you and me — participating with their own dogs. Submitting health information, surveys, samples. It's citizen science in the most heartwarming form. You and your dog, together, contributing to something that could change medicine. I think about Frosty and I think — that is exactly the kind of partnership dogs have always been ready for. Showing up. Being part of something bigger. Skyler: And then there's another piece of this puzzle that is almost too cool — researchers at Oregon State University have been looking at something that sounds almost science-fiction-y but is completely real. They've been studying the gut microbiome in dogs — that's the community of microorganisms living in a dog's digestive system — and they found early evidence that which microorganisms live in a dog's gut may be connected to how well that dog survives cancer. Specifically, they looked at dogs undergoing cancer treatment and found that the makeup of their gut microbiome seemed to have a relationship with their outcomes. Skyler: Now, this is early research — they're careful to say that — but it's exciting because the same question is being asked in human cancer research right now. The gut microbiome is one of the hottest areas in all of medicine. And here are dogs, once again, helping us understand something that could ultimately benefit both species. Frosty would probably just be happy knowing that scientists care this much. I know I am. Skyler: What I keep coming back to is this idea that the dog-and-human bond isn't just about love, as real and enormous as that love is. It's about partnership in the truest sense. We take care of dogs. And in this very literal, scientific way — they're taking care of us too. They always have been. Skyler: Thread three — Understanding Dogs — and this is where I really geek out, because we're talking about behavior, genetics, A I, and one of the most lovable canine classrooms you have ever heard of. Let's start with the science, because there's a genuinely fascinating conversation happening right now about whether a dog's breed actually determines how they're going to behave — and the answer is a lot more complicated than you might think. Skyler: Dogster recently tackled this head-on, looking at what genetic science actually tells us versus the stereotypes we've built up around breeds over the years. And here's the headline: genes do play a role in behavior, absolutely — but they are far from the whole story. A study published in the journal Science a couple of years ago looked at data from tens of thousands of dogs and found that while breed can influence certain tendencies, it explains a surprisingly small portion of the variation in individual dog behavior. In other words? The Labrador next door who hates water and the Border Collie who couldn't care less about herding — those dogs are not anomalies. They're totally normal. Skyler: What matters just as much — maybe more — is the individual dog. Their experiences. Their environment. The humans in their life. How they were raised, socialized, loved. And I think about Frosty here, because Frosty is the perfect reminder that every dog is their own whole person. You can know a breed's history inside and out and still be completely surprised by who that individual dog turns out to be. That surprise is part of the magic. Skyler: This is actually really important stuff, because breed stereotypes have real consequences. They affect adoption rates. They affect legislation — breed-specific laws that restrict or ban certain dogs. Understanding that behavior is more about the individual than the breed could genuinely change how we treat dogs at a policy level. Science, in this case, is on the side of giving every dog a fair shot. And honestly, Frosty would want that. Skyler: Now, A I is becoming a tool in this world of understanding dogs, and it's a fascinating development. Researchers and technologists are working on systems that can analyze dog vocalizations, body language, and facial expressions to help decode what dogs are feeling and communicating. There are early-stage A I tools being developed that look at things like the pitch and rhythm of barks, the position of ears and tails, the subtle facial muscle movements dogs make — and try to map those to emotional states. Is this dog stressed? Is this dog happy? Is this dog in pain? Skyler: Now, we're not at the point where your phone can translate your dog's every thought — and maybe Frosty prefers a little mystery — but the research is genuinely progressing. And what's exciting is that A I can process enormous amounts of behavioral data in a way that human researchers just can't do at scale. It could help veterinarians catch signs of pain earlier. It could help animal shelters better match dogs with families. It could help trainers understand when a dog is overwhelmed. The potential is real. Skyler: And speaking of places doing creative things with dogs and learning — Eckerd College in Florida has done something absolutely delightful. They've partnered with Dogs Inc, which is an organization that trains service dogs, to create what they're calling a canine classroom. College students at Eckerd are raising and socializing puppies that are being trained to become service dogs. These students live with the puppies, care for them, take them to classes, expose them to all the sights and sounds and people of college life — which, as anyone who went to college knows, is quite a range of experiences. Skyler: And the magic of this is that it works on every level at once. The puppies get the critical early socialization they need to become excellent service dogs — exposure to all kinds of environments, people, sounds. The students get something that I think you really can't teach in a classroom: responsibility, empathy, and a crash course in reading another creature's needs. And the people who will eventually receive these service dogs — who may have mobility challenges, or other disabilities — they get a dog who is extraordinarily well-prepared to change their life. Skyler: That is the bond right there. A puppy, a college student, and someone they haven't met yet — all connected by this thread of care and intention. Frosty would have loved a college campus, I think. All those people to meet. All those backpacks to sniff. All that love going in all directions at once. Skyler: Understanding dogs better — through genetics, through behavioral science, through A I, through programs like this one — it all leads to the same place. Better lives for dogs. Deeper connections between dogs and the humans who love them. And a world that sees dogs not just as pets, but as partners, individuals, and — as Frosty has always known — irreplaceable. Skyler: And that, my friends, is a wrap on today's episode of Frosty the Dog. I hope you're walking away feeling what I always feel after diving into these stories — this enormous, warm sense of wonder at what dogs are, what they do, and how lucky we are to share our lives with them. Every single story today came back to the same thing: dogs and humans, in it together, making each other better. And I think that's about as beautiful as it gets. As Frosty would say — and Frosty would absolutely say this — every day with a dog is a good day. We miss you, best boy. This show is yours.
