Watch out: ~90-minute battery; hard floors only
Sony aibo

What to buy, by buyer
- Older adult or dementia: Joy for All Pup, and the caregiver guide.
- Wants something alive-feeling, not necessarily a dog: Moflin ($429).
- Wants a robot that behaves like a pet: Loona. Can spend $3,000: aibo, now, while it is still sold.
- A child: see the price guide; usually $80–$100 or Loona.
Realistic to hold: Joy for All Pup and metaDog
If the person you are buying for is going to hold the dog — an older parent, someone with dementia, an adult who wants something on the sofa — this is the realism that counts, and it is the cheapest kind to get right. The Joy for All Pup ($179.99) has fur, a weighted body, a heartbeat you feel through the chest, and it barks, sighs and turns its head in response to touch and voice. It runs on C batteries and has no app. It is the dog used in most of the research on robot pets for older adults, which is why we recommend it first for that buyer. The Elephant Robotics metaDog ($189) does the same job with a rechargeable battery and Shiba Inu or Husky styling, from a company that also makes real robotics. Neither walks.

Realistic movement: aibo, then nothing for a long way
Real dog movement — a walk, a sit, a stretch, a head tilt that is not on a timer — costs motors and engineering, and the only consumer robot that has it is Sony aibo ($2,899–$3,199): 22 axes of motion, a gait that adapts, and a body language people read as canine within minutes. It is hard plastic and obviously a robot. Sony is winding down sales in Japan; U.S. sales continue for now. Below aibo, the walking robots are Hengbot Sirius ($1,299, waitlist) and the Petoi Bittle X ($319 kit), both robotics products rather than pets. Every furry walking puppy sold online is a plush toy with a motor in it.
Realistic behavior: aibo and Loona
Behaving like an animal means recognizing you, remembering, and acting without being told. aibo does this best. KEYi Loona ($439–$499) does a surprising amount of it for the money: face recognition, games it initiates, a return-to-dock routine, and voice conversation through GPT-4o that is currently free. Loona rolls on wheels and has a screen for a face; nobody will mistake it for a dog, but adults who live with one describe it in the language of a pet. It needs Wi-Fi and its intelligence lives in the cloud, which is the trade.

The one that is supposed to do all three
Tombot Jennie is a robotic Labrador puppy built with Jim Henson's Creature Shop for people with dementia: fur, weight, lifelike head and tail motion, voice response, and behavior designed to hold up for someone who cannot follow an app. It is the product every "AI puppy" ad borrows footage from. It has no published price (its CEO has cited about $1,500), a free waitlist, and no confirmed ship date. If it ships as shown, it will be the most realistic robot dog for adults by some distance. Until then, it is not a purchase.
Why the $35 "AI puppy" ad disappoints
A robot dog can be realistic to hold (fur, weight, warmth, a heartbeat), realistic in how it moves (walks, stretches, wags), or realistic in how it behaves (knows you, learns, decides things on its own). In 2026 you can buy any one of the three done well, two of them at a high price, and none of the three together. The $35 "AI puppy" in the ads claims all three; it delivers none. That gap is the whole story of this category. If the search that brought you here was prompted by a video of a furry puppy sitting on command for $34.99, read what those ads actually ship before you order.
