Wait that's an excellent idea! We've had 'real dolls' for decades, and these same methods could be applied to the ascetics of a dog android. And canine behaviour is more easily modeled, more easily mimicked, we could throw a very simple AI in there. No highly dexterous hands to concern one with either.

This is the perfect way to start on human androids. Cut our teeth on this, perfect this, then use the same knowledge to build humanform robots. The patents we'll accrue make it worth it on its own!

Best part is you wouldn't NEED to take them for a walk. No need to clean up their leavings. And if you wanted that part of the experience, it could be fertilizer, clean, specifically designed to help the local plants. We could make a mint selling it, plus, we'd ensure no pesky odour.

Or even better, what the dog simulates as leavings, could be bird food or some such! Each packaged drop, would feed the local pigeons, self-cleanup!

And dog treats! We'd have them beg for treats, but their innards will only accept treats made, and licensed specifically for the dog. In fact, without our specific dog food, the animal will "wither" and die!

We'll make a killing!

Johnson, get the design team in here pronto!

Herding skills, sheepdogs https://www.youtube.com/watch?v=lAjc502ALOM

Also reminded - we had neighbors with 2 cats, an experienced and cynical large red one and a naive curious tabby. They spent a lot of time outdoor wandering around, and the tabby was always trying to get everywhere, very friendly, and the red one was always very suspicious about everything and very worried and watchful over the tabby. Unfortunately the tabby got killed by a car. The neighbors after some time took another cat. The red one never let the new cat to leave their patio. Getting to sit on the patio fence was the maximum she would let him, and on any attempt to get down outside of the fence she would firmly herd him back.

SethMurphy•2h ago
It always fascinated me that particular behaviors, like herding, can be so ingrained to a particular breed of dog. The dog is no longer in a setting where this is crucial to their survival, yet the urge exists. I do wonder for how many generations the behaviors would last, assuming the dominant genes were not surpressed. That is of course assuming genes are the factor that drives it. It's almost as if environment has little to do with the behavior in this case, other than having opportunity to exhibit the behavior.
krisoft•2h ago
Idk if the "herding behaviour" is a useful way to think of this. Imagine that we didn't speak the same language, you went for a swim in the ocean and I would go after you and dragged you back to shore while shouting (in my own language) "Oh my, that is so dangerous. Do you even know how many people drown like that? Stop this lunacy at once". Would you describe my behaviour as "herding"? Would you talk about generations, and dominant genes? Or would you just say "this person has some fear for my safety (well grounded or baseless) and seems to care enough about me to save me from the danger he perceives, while I can't convince him that it is fine because we don't speak the same language."
kid64•2h ago
This analogy might work in a universe where dogs speak foreign languages in which they learn about concepts like danger, persuasion, and language itself. Sounds fun.
krisoft•43m ago
> in which they learn about concepts like danger, persuasion, and language itself.

Dogs definitely know about the concept of "danger". Roaring fire, a raised stick, or loud noises. These are all things which doesn't cause immediate pain but they react to avoid them. It seems from the story Lenny includes in the things he want to avoid the ocean while Arthur doesn't. That sounds more like an individual difference than a genetic predisposition.

You don't need to speak a foreign language to have this concept.

I don't know what is your definition of "persuasion". If it involves the behaviour of standing in someone's way and bothering them until they turn back then we can agree that Lenny seems to have the concept despite not having a language.

We had an Old English Sheepdog called Bob who let kids climb trees but only up to a certain height. If you went higher Bob grabbed your ankle and gently pulled you back to the height he previously "let you". Otherwise you could do whatever you wanted to do on the tree and he didn't care. Otherwise never herded anyone ever.

My point is not the language. More that if a chinese coast guard would drag you out of the sea you wouldn't be saying "yeah the chinese have a strong herding reflex". You would say "this person doesn't want me to swim", or "this person thinks I'm in danger and I can't communicate that I'm not".

diggan•1h ago
This sort of "herding behavior" isn't just noticeable when you go out to swim, but any time 1+ people are apart from each other. You can spot these dogs extremely easily when you have a bunch of young children playing together, and you can see the family dog paying attention and as soon as one strays away from the group, the dog will start engaging and carefully nudge the stray kid back to the group.

There is no inherent danger in those situations, yet the dogs prefer if everyone was together in a group. If that's not "herding", I might just not understand what herding really is.

krisoft•17m ago
What do you describe sounds like herding behaviour, yes. When I say it is not a good description for "this" I mean the behavioural difference between Arthur and Lenny. Maybe you read it as if I don't believe in herding in general? That would be indeed silly on my part.
closewith•1h ago
Herding behaviour is so distinctive and so apparent in certain breeds that it's nonsense to dismiss like this. Peak HN arrogance.
krisoft•1h ago
> it's nonsense to dismiss like this

I'm not dismissing herding behaviour. It is a thing. But genetics is simply not a good explanation for the story here. Here we have two dogs of the same breed (Arthur and Lenny). One lets their owner swim freely the other doesn't. The difference here is not genetics (they are the same berad), this in my opinion is a personality difference between the two dogs.

Which is why I'm starting my comment with "Idk if the "herding behaviour" is a useful way to think of this." Calling it "herding behaviour" doesn't explain the difference between the two labradors.

> Peak HN arrogance.

So lovely. Would you say that to my face closewith? I was nothing but polite to you and everyone else. I'm a human here you know. Can you treat me like one?

Veen•45m ago
It is not polite to assume that you, after a brief amount of thinking with no background knowledge, have overturned centuries of empirical and scientific knowledge of canine behavioural heredity. It is astonishingly presumptuous. And it is, indeed, peak HN arrogance to make that assumption.
krisoft•29m ago
> It is not polite to assume that you, after a brief amount of thinking with no background knowledge, have overturned centuries of empirical and scientific knowledge of canine heredity.

I do not claim any such thing. Simply that the difference in behaviour between two dogs of the same breed cannot be explained with genetics. Lenny and Arthur share a genetic background. They do not share the behaviour. There is some other difference between Lenny and Arthur (or between the two swimmers!) which drives the difference in the observed behaviours.

I'm not saying genetics is not a thing. It is simply not the right lens to inspect this situation here.

> And it is, indeed, peak HN arrogance to make that assumption.

Which I'm not making. In any of my comments. So we are good then. :)

Gets a face full of water and it stings its nose. Looses footing as it gets deep and doesn't like it. Hears the distant waves roaring and doesn't like it. Sees its human breath differently and move differently and doesn't like it. Looks at its owner and sees them getting small (just a bobbing head on the water) and doesn't like it.

Can be so many things.

4gotunameagain•2h ago
I was flabbergasted when I learned that herding dogs have the instinct to bite behind the legs, even of humans. It is a pressure tactic to make the herded animal go in a certain direction.

To me this is an (unpopular) argument against the tabula rasa theory of humans.

If such a complex behaviour can be congenital, who knows what behaviours are congenital in humans.

cm2012•1h ago
Tabula rasa theory is not close to plausible with the scientific evidence we have, unfortunately.
closewith•1h ago
Why is that unfortunate?
4gotunameagain•1h ago
One reason is because it will forever be an argument against equality by some who feel superior. Because some might believe they have the right to take decisions for others based on their perceived superiority, even if differences are incomprehensively multidimensional and humans who usually think of themselves as superior they lack terribly at other dimensions.
golergka•23m ago

bite behind leg doesn't sound so complex.

bite behind leg if multiple animals going towards X but animal A goes towards Y and biting will make A go towards X would be complex.

bite behind leg is simple and crude and by placing dog in right context produces complex and useful results.

OgsyedIE•34m ago
It still requires solving the symbol grounding problem. How does DNA code for the brain's network weights that correspond to things like the definitions [non-prey target], [goal location], [incentive], [coerce] and [back of leg], or some other suitable set of concepts?
isoprophlex•23m ago
Birds building elaborate nests is something I can't wrap my head around. How do you encode that in DNA, and have a (comparatively tiny) brain execute such complex social behavior?!
Hendrikto•6m ago
There are insects with much much smaller brains than birds, that also exhibit quite complex nest building behavior.
bryanrasmussen•6m ago
I would say from reading the description it doesn't have to do all that, because it sounds like the dog is biting indiscriminately at backs of legs of any reasonable large animal, since it is also biting at the backs of human legs. So I think it doesn't really do any non-prey target reasoning, it just does target size X has back of leg, also I don't know based on description that it does incentive - what is the incentive of biting the back of human legs?
4gotunameagain•23m ago
To me it sounds complex enough to bite behind the leg, not leg in general, and not the leg of a chair for example.

I do not think a dog has to solve partial differential equations for me to be impressed and think that complex behaviours can be innate.

It is crucial to their survival. That's how they made it to this day in these numbers.

golergka•25m ago
Reproduction and evolutionary success in breeding conditions are not the same thing as survival. No breeder kills off dogs with unwanted characteristics, they just don’t breed them.
jcynix•6m ago
> No breeder kills dogs […]

I sadly have to disagree as history tells us a different story, e.g.

"Back in the day, puppies without a ridge were either euthanized or culled at birth." https://healthyhomemadedogtreats.com/ridgeless-rhodesian-rid...

I learned that when I met such a dog the first time some years ago and the owner told me about this. And I would not bet that it actually is "history" nowadays.

My dad would go fishing on the beach with his formula 1 labrador. While my dad was in the water fishing, the dog would swim around him in circles. It could swim for an hour without break. It was very cute and impressive, but of course it would also scare the fish away. The dog would also be quite curious about the seals, but I've never seen them play like in the article. A lovely dog, but they have an uncontrollable appetite which can be pretty annoying.
05•51m ago
Labs are so obscenely food motivated it's a mystery why the owner couldn't train Lenny to just follow them for a few bits of kibble. It's not like they're shepherds in the first place, so herding drive can't be that strong (unless it's a mix).
JSR_FDED•28m ago
There’s two strains of Labrador, often called the British and the American. Then British are the traditional goofy food-obsessed family dogs. The American are more working dogs - much more energetic than their British counterparts and less motivated by food than the opportunity to catch a ball.
franktankbank•14m ago
I don't really know what you mean, American labs don't have any sort of genetics that tells them to stop eating. If they were in a room filled with food they would eat it all, only taking breaks to sleep. I have a lab mix and he shamelessly steals food from our young kids and off the kitchen counter as we eat in the very visible room next to it. He's eaten whole loaves of bread (multiple times), an entire pound of deep fried egg rolls, trays of cookies on and on and on. He's a good boy though.
lordnacho•16m ago
I have labs, and they seem to have perfected the art of begging. Not too pushy (no barking), not too subtle. Just you know, when you're eating or moving towards food, it somehow crosses your mind that maybe the dog should have something. Always happy to do the one trick that gets them food, which is sitting on their hind legs.

I can see how this evolved. You sit near the humans, don't act aggressive, they give you food. You make puppies that follow the same plan. You give up the dead end profession of providing security. The parcel guy might also give you food, you never know!

What I don't get is how their other instinct evolved: "I must bring this tennis ball to master, and master must fulfill the social contract of launching it"

Sure, I can see how hunting for stuff makes you want to run over to something and pick it up. But what about the "throw the item 40m so I can run after it?" Why would that have a purpose? Why is the appetite for doing this insatiable, to the point where you are advised not to do it with small puppies who might hurt their hip development? Is it all just an extension of the juvenile stage, where play is important?

Labs have also become the dominant breed of dog through exceptional salesmanship. I bred my lab, and she had eight puppies. We advertised them, and not a single one of the families that came to see one decided against it. The mom would bring a puppy to the family, and as soon as they were holding a puppy, you could tell by the look in their eyes that they were sold. It's like she was saying "Hey, you look like nice people, buy my kid! He'll love you forever".

The puppies at that stage are already able to look deep in your eyes, and can already do the "oh hey, that's some interesting food you got there" look, and they already love a belly rub.
