The first time Mira, a 72-year-old retired nurse in Seoul, interacted with a robot dog, she cried. Not from frustration, but from surprise. "It responded to my voice," she told a researcher documenting the experience. "After my husband passed, I didn't think anything could fill that silence. But this little machine... it waited for me to speak."
Mira is one of roughly 10,000 South Korean households now deploying Hyodol robots for elderly care [5]. And she represents something bigger: a fundamental shift in what companionship means in an era of aging populations, urban isolation, and rapidly advancing robotics. Robot dogs are no longer curiosities or luxuries. They're becoming viable alternatives or complements to living pets, especially as prices drop and capabilities improve.
The question worth sitting with is what this says about us, and where this trend might lead.
What's Actually on the Market
Walk into any consumer electronics showroom today and you will likely find at least one robot dog waddling, sitting, or performing tricks on a demo table. The market has exploded in the past five years.
Sony's AIBO remains one of the most recognizable names. The fourth-generation ERS-1000, launched in January 2018, can recognize up to 100 faces and responds to over 50 voice commands [1]. At approximately $3,000, it's positioned as a premium companion. The original AIBO actually predates many of today's AI trends. Sony introduced the first model on May 11, 1999, and it was eventually inducted into the Carnegie Mellon University Robot Hall of Fame in 2006 [1].
But the real growth story is Unitree Robotics. The Chinese company, founded by Wang Xingxing in Hangzhou in 2016, has become a dominant force [2]. Their Go2 quadruped robot starts at just $1,600 [3], making it dramatically more accessible than the $74,500 Boston Dynamics Spot [3]. At CES 2025, Unitree showcased the Go2 alongside wheeled-leg variants and their industrial-grade B2-W, signaling ambitions beyond purely consumer markets [8].
The price stratification is telling. You can now buy a basic robotic companion pet for around $120. Hasbro's Joy For All line makes this possible [6]. Or you can spend $6,120 on PARO, a therapeutic robot seal used in hospitals and nursing homes that has actually demonstrated reduced anxiety in dementia patients in clinical studies [6]. The range reflects a genuine diversity of use cases, not just marketing gimmickry.
So how big has this market actually become?
The Numbers Behind the Boom
Unitree filed for an IPO on the Shanghai Stock Exchange in March 2026, seeking to raise 4.2 billion yuan (about $610 million) [2]. The filing revealed something remarkable: the company posted adjusted net profit of 600 million yuan ($90 million) in 2025, a 674.3% increase from 2024 [2]. Revenue surged to 1.71 billion yuan ($250 million) in 2025, up from just 392 million yuan ($57 million) in 2024 [2].
Between 2022 and September 2025, Unitree shipped more than 30,000 quadruped robots [2]. They accounted for roughly one-third of global humanoid robot sales in 2025 [2]. In that same year, Unitree sold 5,500 humanoid robots. Though it's worth noting that over 70% of those went to research and educational institutions [7]. The consumer market for robot companions is growing, but the industrial and research market is where the revenue is right now.
Average robot prices have fallen sharply. The average price of humanoid robots fell from roughly $85,000 in 2023 to $25,000 in 2025 [7]. Unitree plans to produce 75,000 humanoid robots and 115,000 quadrupeds annually over the next five years [7]. That's a production scale that suggests robot companions are moving from niche to mainstream.
So why are people actually buying these things?
Who Is Buying Robot Dogs and Why
The market breaks down into several distinct groups, each with different motivations.
Seniors and isolated adults represent one of the largest segments. PARO, the therapeutic robot seal, has been used in hospitals and nursing homes for years, and studies in Texas and Kansas showed decreased anxiety among dementia residents using robot-assisted therapy [6]. The Hyodol robot deployed in approximately 10,000 South Korean homes takes this further, providing not just companionship but data collection. These robots gather information about users and yield feedback based on interactions, enabling remote monitoring by family members or caregivers [5]. For elderly people living alone, a robot that never needs to be fed, walked, or taken to the vet might be the difference between unbearable solitude and manageable loneliness.
Children and families form another growing segment. Robotic pets like WowWee's Robopet or Hasbro's Furby Real Friends offer a gateway for kids to experience caretaking without the full responsibility of a living animal [4]. Parents who cannot commit to a dog or cat, perhaps due to allergies, apartment restrictions, or work schedules, can offer something that responds, interacts, and teaches empathy without the early-morning walks.
Tech enthusiasts and researchers make up a third category. At $1,600 for a Unitree Go2, hobbyists and developers can actually afford to experiment with quadruped robotics. The Unitree G1 humanoid robot, priced at $16,000, can walk at over 4.4mph, climb stairs, and features 23 degrees of freedom through powered joints [3]. It learns through imitation using Unitree's Robot Unified Large Model (UnifoLM) [3]. This is not just a pet. It is a platform. For researchers and developers, the appeal is not companionship; it is the possibility of what you might build on top of the hardware.
So what does this mean for the traditional pet industry?
What This Trend Tells Us About Modern Companionship
Here is the uncomfortable truth: many people want the emotional benefits of pet ownership without the practical burdens. And robot dogs are increasingly able to deliver those emotional benefits at a fraction of the cost and commitment.
Most consumers buy robotic pets seeking similar companionship to biological pets without the care drawbacks [6]. That phrase contains an entire social commentary. We have created a world where people work longer hours, live in smaller spaces, delay parenthood, and increasingly live alone. The traditional pet requires time, space, and consistency that many people cannot guarantee.
Robot dogs do not need walks at 6am. They do not need someone home for lunch. They do not trigger allergies or damage deposits. They can be turned off and put away when travel beckons. And they are getting smarter, better at recognition, at response, at the illusion of understanding.
But the deeper question is whether the companionship they offer is fundamentally different from what a living pet provides, or simply less. Some researchers argue that social companion robots address unwanted solitude directly [5], suggesting that the mechanism of comfort is less important than the outcome. Others worry that substituting mechanical presence for organic connection might reshape our expectations of relationships in subtle, concerning ways.
Perhaps the answer is not either/or. In Japan, Lovot robots, featuring over 50 sensors and designed specifically to make users happy, coexist with traditional pets in many households [5]. Sony AIBO has been revived multiple times across decades, suggesting genuine sustained demand rather than novelty [1]. As prices continue falling and capabilities improve, robot companions may become one more option in a spectrum of ways people seek connection. Not a replacement for living animals, but a new category entirely.
What happens when a machine that costs $1,600 can genuinely reduce loneliness for someone who cannot care for a living pet? Is it fair to call that a lesser form of companionship, or to judge the person for choosing it?
These are not questions with easy answers. But they are questions worth asking as we watch this market grow from a niche hobby into a global industry.
