If there's a frisbee or ball in sight, my female border collie won't even attend to basic bodily needs. And she'll chase the object while she's in pain and exhausted or shivering with cold and not notice. She has lupoid onychodystrophy which causes her nails to come in deformed and split and painful and she'll still obsess on some running play/task while she's got bleeding paws and can barely walk. An an owner we have to intervene to remove the object of obsession and force disengagement.

This is a product of centuries of breeding to focus on a task and enjoy the task above all else.

>Behavioural addictions, characterised by compulsive engagement in rewarding activities despite adverse consequences in the long term, are more heterogeneous and less well-understood than substance addictions

Indeed. Mostly because every study on "behavioral addictions" is published in third tier journals or is a negative result in real journals. It's something that doesn't actually exist in mammals and it's current popularity is mostly from profit seeking scams for rehabilitation "clinics" preying on the 'screens are addictive' meme burning through current parent populations.

And despite the headlines suggesting otherwise, and the press likely running with those false headlines, *the actual study itself does not find any addictive behavior*. A null result.

>Despite the observed parallels between high-AB dogs and humans affected by behavioural addictions, we refrain from conclusively characterising high-AB dogs as exhibiting addictive behaviour, given the absence of established benchmarks or standardised criteria. It is important to be cautious when pathologising behaviour, especially given that even in humans, addictive behaviours are still difficult to define and measure.

What about gambling, eating, or shopping?

superkuh•3h ago
Gambling is not an addiction. It is "gambling disorder" and it was grandfathered into the DSM. It is explicitly not an addiction medically. Eating and shopping are two great examples not erronously grandfathered in, which committees repeated find are not addiction, but which those scammers love to profit off of.
hippo22•3h ago
"Gambling Disorder" is in the disorder class "Substance-Related and Addictive Disorders" in DSM-5 though.

Pulcinella•2h ago
So why do you think people continue to gamble, even after it has ruined their and their families lives and finances? Slot machine addicts will literally void their bladder rather than stop playing for 5 minutes to use the restroom.
quotemstr•2h ago
Because people make poor choices and it's usually their own fault.

We used have words like "vice" and "sin" to describe these poor choices, but thanks to post-60s radical individualism, the only vocabulary for describing maladaptive behavior that remains of the language of medicine. Therefore, everything bad someone does is a "disease" for which he needs "therapy" or "treatment". We've utterly lost the capacity for describing deficiencies of the conscience.

Pulcinella•1h ago
Why would many, many, many people choose to piss and shit themselves in public instead of stopping for a few minutes to use the restroom? Why would someone choose the push a button every 5 seconds to the point where it ruins their life?

Put it another way: why would gambling companies continue to develop gambling machines? Why not stop with the mechanical, one-armed-bandit of the early 1900s if what they do has no effect on people?

quotemstr•1h ago
Perhaps by the time someone's at the shitting at the seat phase of a gambling habit the neurological feedbacks arising from the intermittent reward schedule have become too strong for him to resist on his own.

But who made him start gambling in the first place? It's not like people who start gambling don't know how it ends. The most addictive slot machine in the world can't compel someone to sit at it for the first time. People KNOW these machines are addictive and choose to use them anyway.

It used to be cultural common knowledge that the wages of sin is death.

Eric_WVGG•2h ago
My understanding was that self-professed gambling addicts — unlike casual gambers — were discovered to get the same shot of dopamine to their system when losing as the do when winning. Why would that not qualify as “medically addicted”? (IANA-Doctor)

It's not "Nature", it's "Scientific Reports" with impact factor of only 3.8 vs 48 of "Nature".

Sure the publisher is "Springer Nature", and the domain is "nature.com" but that doesn't make the journal "Nature".

can you provide more context for this claim? my intuition and experience tells me the opposite.

what is the definition here? are impulsive avoidance copings like playing a video game instead of doing the hard work of addressing the worries/planned hard activities not a “video game addiction”?

and if we are talking physical withdrawal, then how should we call the same aspect of nicotine/alcohol addiction mechanics?

qnleigh•3h ago
> given the absence of established benchmarks or standardised criteria

The quote you cite doesn't support your claim. If there is no established criteria, then no amount of evidence will establish the link. But absent a rigorous definition, they are still giving evidence for a qualitative similarity between human addiction and the observed animal behavior. That's not a null result.

dvfjsdhgfv•3h ago
Well, my fellow CBT practitioners would disagree.

There are things you don't do but you understand not doing them is hurting you, so you decide to follow CBT (for example - there are other ways, but CBT has decent efficiency although it's expensive). They don't really need to be classified disorders or fobias.

Similarly, there are things you do and you realize not doing them would be beneficial to you. So you try to stop them and you realize it's hard. Again, you can use CBT or another method (or even medication in some cases). Whether you classify these things as "behavioral addictions" or use another term is secondary, the phenomenon itself is very real and I find it baffling anyone would dispute that.

  Perhaps not surprising, working breeds – many of which are known to have been artificially selected for high toy or predatory motivation – were overrepresented in the sample.
This is the vibe I get from my golden retriever. Chasing the tennis ball is more than play, it's a justification for life, her contribution to the pack. Actually eating food has a higher priority than chasing the ball, but not much else does. When I got her I thought that the "retriever" part was optional but it turns out to be obligate. As in I'm obligated to throw the damn ball.

philiplu•1h ago
Sorry - my 9 year old golden doodle still doesn't get the concept of fetch. He's an expert at keep-away though. Throw the toy or ball, he'll chase it gleefully, then come back to just out of reach, drop the toy, and hover over it waiting for me to make a move at it. He'll lunge for the toy, back up a bit, drop it, and the cycle continues.

4 year old golden doodle, exactly the same thing.
HankB99•1h ago
Our kids have a Rottweiler that loves to chase a ball, Bring it back and then dare us to try to take it away from her. She can drop if convinced. Or I have a second ball that is more interesting, causing her to drop the other ball. She can hold two balls in her mouth so I have to wait for her to drop the first ball before I throw.

She also has a large (about 1 food diameter) ball that can't possibly fit in her mouth and I can kick that at which point she'll drop the little ball and try to get the big one in her mouth.

The dog is not reflecting on its true nature. If that is true, then it's possible there are many beings, including us, who are not reflecting on their true nature. It shows the meditative power a human actually has. For example, if a parent actually sits down and realizes they'd die for their child no matter what, it would sort of be like the dog realizing how far it would go for a tennis ball. Only a human being can reflect and change, the dog cannot (it's one of the reasons humans fall in love with dogs, they realize the thing is utterly innocent).
qbit42•2h ago
Is this falsifiable? I would be hesitant to claim that this is unique to humans. I'd probably agree with dogs, but the line is much blurrier with primates, for example.
ivape•2h ago
I'm open to any evidence. I doubt we can find a Chimpanzee that sat, thought about it for awhile, slept on it, and then decided it's time to live like a Bonobo. I think the best evidence we have are actual metamorphosis that you see from a tadpole over to a frog, things of that sort. We're the only species that can do something to our nature actively.

There’s some documentation out there suggesting the original Labrador retrievers had food obsession as a trait in common with bidability, which is why more than half of them end up chonky. Not all have the gene but odds are high.

There’s a guy who trawls dog rescues looking for retrievers who are toy obsessed and then trains them to hunt truffles. He reasons you can’t reward them with food for finding even tastier food, so you have to train them with ball time as a reward/distraction when they find a trove.

bell-cot•2h ago
From a dog's PoV, are truffles actually tastier than high quality dog treats?
sqircles•1h ago
Labs in general are notorious for having insane food drive to the point where when you run into one that does not, they're certainly an exception. All dogs in general have food drive, as it is a necessity to live, but they're given basically unlimited access to it which diminishes it's value in their psyche.

Once you pull that prey drive out of a working dog and associate it with something such as a ball, there's no greater satisfaction this planet than doing the thing for that animal. It usually works better as a reward for what we're doing, is more instant, but also it can be deadly for a dog to eat food when they're at working-level activity.

brandall10•1h ago
I grew up with a cocker spaniel obsessed with tennis balls to the point of covering his food with them and letting it rot. Looking into his eyes conveyed no emotion and he didn't seem to care much for affection. He was a tennis ball tracking machine.

There was nothing you could do to satiate his desire. If you gave in to a catch session, you could throw it 100 times, he would start coughing/convulsing from exhaustion, yet still drop a ball at your feet begging you to throw it. You could probably have killed him with it.

If no one was playing catch with him he would spend hours scouring the neighborhood for balls hidden in bushes. At one point I believe he had over 20 balls piling up in various places in our backyard. We would regularly take his balls away so he only had a couple, but more would magically appear.

We did have a little fun with this. My dad would use him as a tennis practice 'partner'. And we built a tennis ball cannon powered by M80s (note: this was mid-80s in the SFV when/where things like bottle rockets and blow guns were legal).

I've had to put down quite a few animals, and he was the only one were there was no sadness, only relief when his time came, esp. after 15 long years of having to pander to this obsessive behavior.

My belief is animals experience something similar to autism, and he was as far along the spectrum as possible, to the point where the only thing that defined him was his working instinct. That million years of mind-meld evolution w/ humans? Simply not there.

i have a Lab/Staffie mix and he has insane retriever drive when we get the tennis ball launcher out. pupils dilate and nothing else matters, to the point that we had to ban launcher because he kept loosing his thumb claws from sliding on the grass when the ground is too hard. Before we banned it his muscles were massive, rippling shoulders etc. When we had his (non-tennis) balls removed he developed insane food drive, the vet said this was common, to the point he'll raid the kitchen at night if we don't lock it down. The boy is build to do 1 of 2 things, eat or fetch!

It doesn't though. Only the headline implies that. If you read the discussion you find the authors of this study do not claim any addictive behaviors were found.
cs702•26m ago
I disagree. The OP states in the first sentence of its "Conclusion" section:

> To conclude, there appear to be parallels between excessive toy motivation in dogs and behavioural addictions in humans.

Understandably, however, the must authors qualify and frame their conclusion, so later on they add:

> Despite the observed parallels between high-AB dogs and humans affected by behavioural addictions, we refrain from conclusively characterising high-AB dogs as exhibiting addictive behaviour, given the absence of established benchmarks or standardised criteria.

herghost•3h ago
We've recently come to this conclusion with our Cockapoo. His mother was a working Cocker Spaniel.

When the weather is poor we have often tried to get shorter walks in dry spells but augment it with as much ball time as possible to make sure he's getting enough exercise (since he generally dislikes bad weather).

It's become apparent that there's no possibility of satiety through chasing the ball though. He will simply go forever, however tired he looks.

I joked that as a Labrador will seemingly eat itself sick, a Spaniel will run itself lame.

JimBlackwood•1h ago
For a breed that is partly bred to flush out game, throwing a ball is incredibly adrenaline inducing and will not tire them out - they’ll just keep going till they fall down. Working cockers are one of the breeds susceptible to exercise induced collapse, albeit rare it shows how insanely motivated they are.

To get them tired, you need to chill them out and have them use their brain and/or nose.

Maybe try some sniffing games, sit down during the walk and have them just take in the environment, do some obedience that makes them think, or throw their food in the grass and have them figure it out.

callamdelaney•3h ago

One of my best friends has a toller (canadian duck retriever) that's a total ball junkie, it's all he seems to live for.

Nowadays I try to just play frisbee and tugging games whenever I'm over for some time. When a ball is in sight, the world just disappears.

rini17•1h ago
It's pretty hard to avoid any situations where pulling is possible. Such as on leash. You usually have to intensely train working dogs not to pull on leash.

They would still fixate on other behaviors they are trained on. And if not trained and neglected, often have destructive behaviors.

My dog (Briard) isn't just addicted to play fetch with balls.. Since he knows that when another dog enters the dog park, the ball will be removed/hidden from him (to prevent the dogs clashing trying to get the ball), he becomes hostile to the dog entering the park, actively trying to prevent them from doing so! This happens only if we started to play with balls. If not, he'll be totally friendly... What an ass!

I read somewhere that domesticated dogs are to some degree bred to stay in their "childlike" state, so in a way they act like wolf puppies that never get older. Probably different breeds have different degrees of this. But anyway, I wonder if there is supposed to be some counterbalancing "maturity" or "responsibility" impulse that would cause them to decide not to do the thing, but since that has been bred out / disabled, they just run on impulse forever.

Incidentally I feel this way also: like I never fully grew up, and I easily regress to being trapped in a childlike state where I'll e.g. play video games all day. To snap out of it I have to "remember" to be an adult, like it's easily forgotten especially if my daily life doesn't ask me to have any serious responsibilities. maybe dogs don't have any responsibilities so they have no reason to stop playing.

This is a really fun 16 minute listen to how this precise dog behaviour is exploited to eradicate rats on Lord Howe Island.

They search specifically for dogs obsessed with ball chasing and turn them into rat hunting dogs.

There's funny bit where they talk about finding a dog that had learned how to use the tennis ball firing machine and spent all day chasing a tennis ball and putting it back in the machine which fires the tennis ball in a never ending loop.

Slightly off topic, but I once had a Siamese cat. I could not teach her to fetch a ball, but she could very well teach me to throw again. And it had to be a yellow foam ball - none of the other colors were of any interest.
