Can our pets really say ‘I love you’? Science is finding out - University of California

Skyler: Hey there, dog lovers — welcome to Frosty the Dog, the show where we celebrate the most wonderful creatures on four paws. I'm Skyler, your host, and I am so happy you're here. This show is named for Frosty — the best boy, my heart, the dog who inspired every single episode — and we celebrate him in everything we do here. We've got an amazing lineup today: science that'll make your jaw drop, a story about the bond between dogs and people that I have to warn you might make you cry, and some really cool stuff about how we're learning to actually understand what our dogs are thinking and feeling. 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 also want to thank Ada, who helps clients integrate A I into their workflows — they are doing some genuinely cool things; Ago Consulting — that's "Ahh-Go" Consulting — silicon development consulting from A I to SoC; and Zen Semiconductor, an umbrella company with a portfolio of companies across the silicon industry. We are so grateful for all of them. Now — let's talk about dogs. Skyler: Okay, thread one — Dog Science and Discovery — and oh, do I have something good for you today. So here's a question that I think every single person who has ever loved a dog has asked: does my dog actually love me? Like, really? Or is it just that I have the treats and the food bowl? I think about this with Frosty all the time. He'd give me that look — you know the look — and I'd think, buddy, are you telling me something right now? Well, science is getting really, really close to an answer, and what they're finding is genuinely beautiful. Skyler: Researchers at the University of California have been digging into this exact question — can our pets actually communicate love to us? And what they're discovering is that yes, dogs have a whole repertoire of ways they express deep emotional attachment. And it's not just tail wags, though Frosty's tail wag could have powered a small wind turbine, so let's not dismiss those either. Skyler: Here's what the science is showing. Dogs have evolved — over thousands of years of living alongside humans — to be extraordinarily tuned in to us. They read our faces. They track our eyes. They respond to our emotional states in ways that are genuinely sophisticated and that go way beyond simple conditioning. When a dog looks into your eyes, both you and the dog actually release oxytocin — that's the bonding hormone, the same one that flows between a parent and a newborn baby. That is not nothing. That is biology saying: this connection is real. Skyler: And it goes deeper than that. Dogs adjust their behavior based on how they think we're feeling. If you're sad, a well-bonded dog will often come and just... be near you. Not because you asked. Not because there's food. But because something in them responds to your distress. Researchers call this empathic responding, and it's one of the things that makes dogs genuinely unique in the animal kingdom. Skyler: What the UC researchers are exploring now is how dogs communicate these feelings back to us — what are the specific signals, the postures, the vocalizations, the gaze patterns that mean "I love you" in dog? Because if we can decode that language more precisely, we get closer to understanding what's really going on inside that wonderful furry head. And I'll tell you what — every time I think about Frosty padding over and resting his chin on my knee for no reason at all, I think, yeah, buddy. Message received. Loud and clear. That was love, and science is starting to prove it. Skyler: The reason I find this research so exciting is that it validates what dog people have always known in their bones. This isn't anthropomorphizing. This isn't projecting. The bond is real. The emotion is real. And science — beautiful, rigorous science — is catching up to what Frosty already knew. Skyler: Thread two — Dogs and Humans — and friends, I have two stories for you today, and they live on very different ends of the emotional spectrum, so take a breath. Skyler: Let's start with something that is a little bit complicated but really important. There's a serious issue unfolding in Florida — and honestly across the country — around fake service dogs. The Tampa Bay Times recently ran a piece about this, and I think it deserves our attention because it's a story about the real service dog bond, and what's at stake when people abuse it. Skyler: Here's the situation. In most of the United States, anyone can walk into a store or a restaurant or board a plane and claim their dog is a service animal. There's no registry. There's no certification that's legally required. Businesses can only ask two questions: is this a service animal required because of a disability, and what work or task has the dog been trained to perform? They can't ask for documentation. They can't ask for a demonstration. And some people — and I say this with real frustration — are exploiting that. They're buying vests online, slapping them on their untrained pets, and calling them service dogs. Skyler: Now, why does that matter? Because real service dogs — and I mean genuinely trained service dogs — go through years of rigorous preparation. We're talking eighteen months to two years of specialized training, often costing tens of thousands of dollars. These dogs are trained to do specific, life-changing tasks. Guide a person who is blind through a crowded space. Alert someone with epilepsy before a seizure happens. Detect a diabetic emergency. Retrieve dropped items for someone in a wheelchair. Interrupt self-harm behaviors for someone with PTSD. These are not tricks. These are medical interventions. Skyler: And when a fake service dog — an untrained dog in a vest — causes an incident in a public place, it creates real ripple effects. It makes businesses more suspicious. It makes access harder for people who genuinely depend on their service dog. And it can put real service dogs in danger if an untrained dog behaves aggressively. It's a public safety issue and it's a fairness issue and it breaks my heart a little bit every time I hear about it. Skyler: Because here's the thing — the real service dog bond is one of the most extraordinary things humans and dogs have built together. Frosty was never a service dog — he was a different kind of essential, if you know what I mean — but I have enormous reverence for the dogs who do this work and the people whose lives they transform. Skyler: Which brings me to the second story in this thread, and I have to tell you — this one is hard. Earlier this year, a woman in California was walking her dogs — three of them — when a truck struck her. And she watched three of her dogs die, including her service dog. I'm going to sit with that for a second because it deserves that. Skyler: This woman's service dog wasn't just a pet. A service dog is a working partner, a lifeline, a presence that makes independence possible. The loss of a service dog is a profound grief on multiple levels — the grief of losing a beloved animal, yes, but also the very real and practical loss of the assistance that dog provided every single day. This story was covered by People magazine, and what struck me reading it was how clearly it illustrates the depth of the human-dog bond. These weren't just dogs. They were family. They were essential. And the cruelty of that loss is almost impossible to put into words. Skyler: I think about Frosty when I hear stories like this. The way a dog just embeds themselves into the fabric of your life so completely that their absence leaves a shape. A Frosty-shaped hole that nothing else fills. And I think that's actually the truest thing I can say about what dogs mean to us. They're not accessories. They're not props. They're woven in. Skyler: Hug your dogs today. That's all I'm saying. Hug your dogs. Skyler: Alright, thread three — Understanding Dogs — and this one I love so much because it's about what we're learning, and how we're learning it, and how some genuinely exciting tools are helping us get closer than ever to truly understanding our best friends. Skyler: So let's start with something that might surprise you. NPR ran a fascinating piece recently about dog breeds and behavior, and the headline really grabbed me: "Your dog is a good boy, but that's not necessarily because of its breed." And this is actually backed up by some really compelling research, including a big genetic study that looked at behavioral traits across thousands of dogs. Skyler: Here's what they found: breed is actually a pretty poor predictor of individual dog behavior. Like, yes, there are some breed tendencies — herding breeds do tend to have certain instincts, scent hounds tend to follow their noses with the kind of commitment that would impress any professional — but when you look at individual dogs, the variation within a breed is enormous. A golden retriever can be anxious. A pit bull can be the gentlest soul you've ever met. And the genes that most strongly predict behavior? They're ancient. They predate modern breeds by a long stretch. Skyler: What this means practically is really important: we should stop assuming we know a dog's personality just because we know its breed. Every dog is an individual. Frosty was proof of that — he was his own entire person, completely distinct from any category you might want to put him in. He contained multitudes, that boy. Skyler: And this connects beautifully to the research around teens and dogs, which comes to us from Tufts University — and yes, I am delighted any time Tufts publishes something about dogs because those researchers are doing such good work. The question they were exploring: can dogs help teenagers cope with peer stress? Skyler: Now, adolescence is genuinely hard. Social stress — peer pressure, social hierarchies, the constant performance of figuring out who you are in front of other people — it's a lot. And researchers at Tufts wanted to know whether the presence of a dog could help buffer that stress response. And what they found is really encouraging. Skyler: When teens interacted with dogs, their stress responses were measurably lower. We're talking physiological measurements here — cortisol levels, heart rate — the kind of data that doesn't lie. Dogs provided a kind of non-judgmental presence that humans, even the kindest humans, can't always offer. A dog doesn't care if you said something embarrassing at lunch. A dog doesn't have a complicated social agenda. A dog just... shows up. Completely. Every time. Skyler: And this is where the understanding piece gets really interesting, because A I is now starting to help us study and interpret dog behavior in ways we never could before. Researchers are using machine learning to analyze dog vocalizations — trying to decode the differences between barks, whines, and other sounds with much greater precision than the human ear can catch. There are tools being developed that use computer vision to read dog body language — the position of ears, the tension in a tail, the micro-movements in a dog's face — and translate those signals into emotional states. Skyler: Imagine being able to know — actually know, with confidence backed by data — whether your dog is anxious or excited or relaxed or in pain. That kind of understanding could transform veterinary care. It could help dog trainers work more effectively. It could help kids with autism who are learning to read social cues practice with a dog — where the stakes feel lower and the presence feels safe. And honestly, it could just help the rest of us be better humans to our dogs. Skyler: As Frosty would say — well, Frosty communicated mostly in tail wags and strategic nudges to the elbow — but I like to think he'd approve of all of this. He'd be very in favor of humans finally getting a little better at listening. He was patient with us. He always was. Skyler: The dream that drives all of this science, all of this research, all of these tools — is really just the same dream that every dog person has ever had. To close the gap. To understand what our dogs are experiencing. To be as good to them as they are to us. And we are getting closer, friends. We really are. Skyler: Okay, we are coming in for a landing, and as always, I want to leave you with this: dogs are extraordinary. They are patient and joyful and loyal and perceptive and they love us with a completeness that we are still — beautifully, humbly — learning to understand and deserve. Today we talked about the science of how dogs express love, the real and serious stakes of the service dog world, the heartbreak and the beauty of how deeply these animals matter to us, and the new frontiers of how we're learning to truly understand our best friends. Every story today made me think of Frosty — the best boy, the good boy, the dog who started all of this — and I hope it made you think of your dog too. Whatever shape that love takes in your life. Skyler: This has been Frosty the Dog, brought to you by Frosty — the best boy — along with Ada, Ago Consulting, and Zen Semiconductor.
