Why your dog isn't the age you think

- "Dog years" is a popular way to estimate your dog's age. Just take the number of years they've been alive and multiply by 7. But really, that's not backed by any science. In fact, researchers at UC San Diego just came up with a much more scientific way to estimate your dog's age. And it blew my mind...

The researchers are clearly incorrect. My dog is 11 and she's still my baby.
Ahahahaa 😆 hope she never becomes old.
I was born a dog I identify as a dog but according to my mom I'm just a baby
My baby boy is literally at least 12 and he literally comes and makes me pick him up like a toddler still 😂 I don't think he's getting older mentally, just physically ❤️
And that's why you're not a researcher
@@Zoykzmc neither are you with those typing skills...
They aren’t measuring age, they’re measuring the rate of development.
I believe they're probably measuring methylation. That's how we quantify biological age in humans anyway.
wont that be the same as body age?
Or prolly the degradation of telomere?
I'd guess degradation would be the measurement
@@emanwhomakesbarrels701 that’s called telomeres*
Not age, but maturity. Dogs reach their maturity ceiling much faster comparatively to humans.
I think they mean several aging factors. I think towards the end it's risk of death doubling rates
This makes sense because according to my brief Google search dogs can finish puberty as early as 18 months, and it doesn't make sense to compare them to 10.5 year old humans.
many humans never mature
Humans mature unusually slow compared to most species. Its related to functional and structural complexity of our brains that take time to fully develop. We also don't stop learning as much as other species when we're adults.
Can confirm. My 2 year old dog has a bad back, watches golf every Sunday, and constantly asks about the weather and mail.
Yep sounds like a normal dog to me
i’m gonna have to ignore this because there’s no way i can justify a 30yo pissing on the couch. she’s simply a baby, your honor
And will always be a baby, that's how we treat them, that's how they like to be treated, that's what those goofballs deserve to be treated.
I love this 😂😂
They never said a 30 year old's average mental capacity.
On one had there's how fast they ageing for their lifespan. On the other is their level of intelligence and problem solving skills, which as I've heard for cats and dogs is comparable to a toddler.
Yes just yes
Couple of things to note here:
First of all, this study was done specifically on Labradors, so you can't assume it's true for ALL dog breeds, especially ones that are quite significantly different, like a Chihuahua.
Secondly, this is done by measuring the amount of methyl groups on the DNA at certain ages. Methyl groups are added by a process conveniently called methylation. Methylation is an important process that helps DNA carry out it's many important functions and with age the quantity of methyl groups decreases.
Methylation sounds like something from breaking bad ......

The telomeres?
It's important to remember that this is a relative age thing. The reality of the situation is that dogs's lifespan just can't be compared to a human lifespan. The are fertile before they are 1, they are mature at 1 or 2, and they usually die around 12-15. Their lifespan just can't really be compared properly to ours
Exactly. Of course they are gonna age faster when they don't live as long as us.
but our hearts can 😜
Dogs after 1 year: im older than you now
Always thought it was really cool how puppies and kittens developed so quickly. Makes sense they're equivalent to a full grown human by the time they're just one
By the time they are 1.5 they are having mid life crisis 😂

They mature faster, we die faster.
Underrated.
but we live longer
@@cgyygc5433 my statement was relative
Actually ageing is logarithmic🤓🤓
We deteriorate faster, and both in regard to our respective life span.
And then there's me who just uses regular years for everything
My dog is 12 and she is still my enjoyment and (for some reason) she is soooooo energetic (sometimes)
"Multiply by 7" is not for young dogs, but for reminding you how much time you have left with your dog as it gives good estimates for how old a lot of dogs live
That's so sad
My dog is old now and this is so true :(
Still doesn't work, since different breeds (mostly different sizes) of dogs have very different lifespans
My dog died at 19, I mean 133. We rescued him when he was between 5-6. They didn’t know where he came from or what his story was, but he wasn’t in good shape. It was obvious he was abused before; starved, bruised, etc. I was a very sick kid at the time with leukemia, but we were able to recover together. Lived with him till the end of COVID when he couldn’t move or live comfortably. COVID made the last years with him doable cause we could be with him 24/7 to care for him, but eventually we needed to let him rest. Rip shaggy
@@Raktasdelespacio I would think It would still work seeing as humans have varying ages at death. Like some live to over a hundred and others live only to 50 to 60 with different things being a factor including race (i.e, breed)
When you consider that dogs can run around and are basically fully functional dogs at just a few weeks of age, whereas human infants are completely helpless and unable to fully walk for anywhere from 18-24 months it makes a lot more sense!
Humans actually have one of the longest prepubescent stages in the animal kingdom.
Yeah. And also when you compare the ages that both reach sexual maturity. If dogs were the developmental equivalent of a seven year old human when at the age of 1, then that would make it really weird that they are usually able to reproduce by then. So the curve makes a lot of sense.

“If you really want to freak yourself out”
*proceeds to say literally the exact same thing just in a different order*
It’s definitely the fact that humans take WAY longer to fully mature. Our brains aren’t done developing until 25, puppies can start walking in like a week
Most animals
Yeah, the issue is humans are too intelligent to be born fully developed, our brains are too large to be matured past the point of severe intellectual disability before we're born
Yup this. Primates in general take more of our lifespan to fully develop. Most species the name of the game is to reach adulthood as quick as possible and get out of that vulnerable childhood state. We however take it to an extreme even for primates, basically spending a third of our lives getting our brains fully developed.
Dogs can start reproduction at 1 calendar year, humans are 12 minimum and 16 ideally.
the brain never stops developing, but most people stop learning and settle into a steady job/life pattern by 25.
Having kids changes your brain and body significantly, as can other things beyond 25.
Ain’t no way that a 30 year old be living rent free in my house
bet he doesn't even have to pay taxes like our dogs in Germany
lmaoo aintnowaaaayyy
Makes sense why dogs look so young still at older ages
This is oddly very intriguing for reasons I cannot yet explain.
There's nothing that you can say to convince me that a 1-year-old dog is the equivalent relative age of a 30-year-old human being.
This is just going by essentially how fast they grow/their body changes. That is it. Its not by intelligence or anything. Theres no actual science going on here its just a comparison.
In biological maturity, not mental 😂
@@picklechinazzboi2991 Well, even mentally too, but compared to a dogs intelligence, not humans.
I believe it
i agree.. it is too unnatural..
They don’t age faster, they just mature faster
People, or at least their bones, only have like three big agings at different rates. So it's similar to people
I think it has to do with sexual maturity when they're young and how close they are to the average expected death age when they're older
Technically, it's both. They reach full maturity proportionally faster, but they also dont live as long in general. In other words, they reach their maximum age sooner than humans.
Humans have long childhood to develop their brains, because big brained human survives better in protected communities than kid dogs in the wild.
No wonder this puppy with only 7 months, is already trying to outsmart me 😂
Imagine seing a 1 year old dog all healthy & full of energy and thinking "that's like me at 30"... Like, wdym??? My back's killing me and I'm 25!!
A 1 year old dog is still a teenager, they don't reach adult maturity until they are 2 years old
@@aether1356I was thinking the same, depending on breed and size it might even be 3 or 4 before they are "young adults". Mine was almost 2 when she got in heat first time, stoped growing around 3.
That's because dogs excerisize mroe than you do. Move your body goddammit
Do some exercise, or your kids will call you grandpa, while also calling their grandpa grandpa😂😂
😂
I think a crucial point everyone is missing here is that every dog’s lifespan is different, making them different “human ages” depending on their breed. A Great Dane at 7 years old would be geriatric, while a Chihuahua at 7 years old is still a middle-aged adult
Yep. My 11 yr old Irish Wolfhound, although sadly in better health than me at 47, is approaching that “freak of nature” age.
@@leumas75 Now that I think about it 11 years old is already a 'freak of nature' for a dog that size! Be proud of how you've cared for them.
I agree completely, my chihuahua IS 7 years old and is pretty much as spritely as he was as a puppy when active, but does sleep a lot more
The humans graph scared the shit out of meeeeee😢😭😭😭😭

“We age slower while we’re young, faster while we’re old.” I felt that in my core.
This is why bangtan said, "Live fast, Die young"
Not taking care of yourself anymore like u used to or even more stress can cause that as well not entirely because of age
I mean we don't though... We still age faster when we're young than when we're old, the difference is just smaller than with dogs. There's a HUGE difference between a newborn and a 10-year-old, but the difference between someone at 40 vs 50 is nowhere near as big.
Yes, also our last decade or two are times when the body is running only because it is supported by science-industrial civilisation and the advancements of medicine. While our mind is barely keeping up. We are not made to live to be 90. In the past most "old" people died in their 70s.
It's not age, it's maturity. Why do people not understand. Dogs do not age faster, they *mature* faster.
And even though that timetable is generally correct each different species of dogs have slight variations to the curve. IIRC the basis for the curve is based on Labradors.
They age and mature faster. That's why they die faster.
@@wolfcat87 everything on earth ages at the same rate… it’s maturity, that’s why a puppy can walk within the first week and humans often need to wait a year
@@oerlikon20mm29 nu nuh
a lot of people use them (maturity&age) interchangeably and act like they're the same thing all the time and it pisses me off to no end. even with humans. it makes no sense to me.
I straight up do not believe a 1 year old dog is equivalent to 30 year old human
Their brain is like 1/4 of a human brain. Of course they don't behave the same way.
If it helps to put it in scale, dogs get puberty around the age of 5 months, while humans get it around 13.
that might be because she has no idea what she is talkign about. she very clearly has never visited a class about statistics and studies, yet tries to analyze them
Yeah behaviour aside, many dogs bulk up and grow into themselves after 1 year old, they still look quite teenagerish to me. I always thought 7 was pretty low though. I've seen charts suggesting bigger and smaller dogs also age differently, which makes sense to me
Closer to a 16 year old.
Dogs aren't the odd ones out. Humans aging so slowly at young ages are the exception rather than the rule. Humans becoming frail and useless sooner after their prime is also against the norm.
Yup. Most animals can fend for themselves after a couple days or weeks. Some fish and reptiles can do this in hours. The fact that we are defenceless for years just goes to show how much societal structures are baked into our DNA. Without adult humans caring for little humans, our species would be dead in the water.
Humanity took many major genetic gambles not found in many other species
We got that massive head, that bipedal shit, the opposable thumbs, the hairlessness, the who endurance hunting and sweating to cool down shit, we are pretty damn unique, not all of them are great payoffs
Most animals have about a billion heartbeats in their life. Humans reach that at about 25
@maxotto9877 It wasn't necessarily humanity
@@OkPe-ww5rs of course not, it happened a long time ago over a long period of time but we are the only species really left with that trait because we killed all of our close relatives
I think they quantify it by certain milestones for example when their bones get their final structure, when they acquire capacity of being able to reproduce, get to their final size (humans usually stop growing at 19-21 i think).
Alongside that, I'm sure they track hormones, proteins and another compound's production
But if we are measuring aging with physical growth and mental development, shouldn't our graph look similar to dogs as well since we grow a lot physically for the first 2 decades and then just stop growing and our frontal lobes develop dramatically until about 25 and then slows down significantly.
I'm guessing they also quantify rate of degeneration; I mean how quickly the body's functions regress & slow down, which would explain why humans "age faster" the older we get
@@ravneetsingh22 this chart is comparing our ageing to dog’s ageing, so a dog reaches similar milestones much quicker than us (if you think about it, sexual maturity before 1 out of an average of 13 years of life, or even 10, is still nearly twice as fast as human, that reach sexual maturity at i’m assuming about 13 out of 72 years of average lifespan). but yes, we do also age a lot faster in our early years
Every single animal on this planet ages quickest between birth and sexual maturity. Time is literally a social construct, so a dog that is 5 years old is genuinely a dog at 5 years old.
Finally someone I can relate two
"time is literally a social construct" what
time is NOT a social construct, there was a study done with bees under multiple different circumstances which proved that they do perceive time. the *labeling* of time we've created is a purely human "social construct" yes, but the perception of time is entirely real. highly recommend reading about the bees if anyone is interested
@@isabelwoodcox time is a stationary observer construct
When you’re trying to compare dog development to human development, you’re basically saying that the dog’s age is equivalent to the human age where we’re at the same point of development. Is it based on a construct? Kind of. Can we use biology instead of random numbers here? Definitely.
Love your videos. They are amazing
The dogs size also matters for that. The smaller the dog the less it ages generally.
Obviously. Humans are infants for an incredibly long period of our lives. Like up to 18 years. Most animals can walk by the time they're born. There's a difference between aging and maturing, and all animals do both at different rates.
I was given the best birthday card from a friend on my last birthday, it just said "In dog years, you're dead" 😂
Lolololol
I believe it also varies by breed of dog.
Many smaller dog breeds tend to have longer life spans than most larger breeds dogs.
Me brain had a stroke when you were explaining it
Also larger dogs will age differently than smaller dogs, there's a lot of factors for many different breeds. It's pretty interesting really.
Reproductive maturity, digestive/organ health, cellular regeneration, cognitive function. What’s wild is the variance of “aging” these four exhibit in a dog’s life.
Clearly a one year old dog is smarter and more self sufficient than a one year old human
Alot of dog maturity depends greatly on the owner / trainer.
Makes sense since dogs grow really fast in the first few months
It doesn’t matter how old the dog physically is, they are all cute babies lol
You also need to look at different breeds, as they have higher or lower average max age.
There are calculator to calculate the dogs age by size / breed.
Many smaller breeds get older than the big dogs and they are very active to a higher age.
meanwhile 130 lb Anatolian Shepherds live to 17 years, on average
I found this out a couple years ago, yet your explanation with the curve diagram is the first time I've seen how we age compared to dogs. My 14 year old dog just got 20 years younger 😁
Part 2 please!
Thanks for your clearly legible cc!! ❤😊
Do most animals have an age curve similar to a dog’s, and relatively few have one similar to a humans?
For example, whales, elephants, apes, other intelligent animals with complex social structures stay with their mothers longer and take more time growing up, so they have more time to develop their brains.
Something like a lizard or snake just pops out of the egg and has to start adulting right away, they don’t have a developmental stage involving play at all. Their curve is probably even more drastic than the dog’s.
I’d love to see a graph like this with a bunch of animals on it.
I think a lot of it will have to do with the size of the animal and their place on the food chain in their environment.
I would suspect that relatively few animals have an age curve similar to humans. Much like you suggested with whales, elephants and apes being more similar to us. We're also all rather large animals compared to most as size does have advantages for survivability.
Interesting take!
Age is based on mental and physical development. Most animals develop very quickly as babies because In the wild they would otherwise die. Humans on the other hand are born not able to walk or speak or hold their own head. They develop much slower.
I saw a chart based on their mental personality compared to humans, instead of 1y = 7y across the board it went something like:
(per year) 3, 3, 5, 5, 5, 7, 7, 5, 5, 3 and so on. But i also heard that dogs don't get past the mental capacity of a 5yo and that makes sense to me in most cases. Until they get older and then they're acting like theyre the elders of our family lmao
Bro my one year old dog still can’t stop peeing in the house💀
bro, that is far too old to be peeing in the house. best case scenario, thats like a 7 year old peeing in the house, or just as likely, thats like a 30 year old peeing in the house.
Puppies should be potty trained by 10-12 weeks old.
@@tigerstallionk
A one year old dog that's peeing in the house needs to stay outside.
If I remember correctly they used several different indices, some physical and some mental. Another interesting fact is they found that smaller dogs seemed to have a flatter curve, which is why the lived longer, where as large dogs had a more inclined curve and shorter lives. It came down to growth hormones that switched off more in small dogs and stayed on longer or never really shut off for the large dogs. I think humans are the outlier on development, which is why it takes so long for us even to walk where all other animals can do it within minuets or at most days.
My dog is 20. Literally off the charts.
How are they? Like do they still play fetch and go on walks or
Part 2? Would be great to know how the quantify this
This actually makes so much sense. Our evolution to have more complex brains requires more time to develop in our early years. Thus, other animals when compared to us in developmental growth would seem fast. However this is just another product of evolution and a fascinating topic.
Essentially, they’re measuring sexual maturity and when the animal stops growing
David Sinclair has great research on epigenetics of aging. Maybe that’ll be a good Huge topic
Love the things you talk about and I always wondered about the dog to human age thing....😊🤔👍
this makes so much sense. when they’re puppies they can fully walk, run, and are aware of their surroundings as human babies aren’t. and my dog is about 13 in human years and he’s just hanging on by a thread and he has been for years. this makes so much sense
They check the genome, DNA has a buffer that gets slowly stripped away every time cells divide. Ageing is when that buffer runs out and to produce new cells through dividing you’d start cutting into that cells function.
Telomeres, they get shorter and shorter as you age.
@@CantankerousDave thank you, understanding processes is one thing the terms are another 😂
I remember the best way to quantify and identity aging is by checking the ability to the cells to retain the necessary dna from replication. That's the main reason i think

I have had this same question on my mind ever since I heard about the 7yr thing for dogs
"More in next video!"
Me seeing the comments: damn, 9 months💀
The older we get as humans the quicker years seem to go by.
It's because a year means less as you get older. As a young child 1 year is a significant part of your life up until then. For example at 10 years old 1 year is 10% of your life. At 50 that percentage drops to 2%. So every year that goes by is less of a percentage of your total life. So the years feel quicker even though they aren't.
Your cells are programmed to divide, multiply, and perform basic biological functions. But the more cells divide, the older they get. In turn, cells eventually lose their ability to function properly. Cellular damage also increases as cells get older
Basically they take some samples of your ( or any species ) cells and they observe them over the span of a life time and see how much or how little your cell divides
That makes so much more sense. Thank you science.
conclusion, dogs can be immortal
Technically dogs age faster than us their whole life
It’s not “aging” it’s maturity levels within the species.
I just intuitively knew this because when I think of animals I always saw how fast they grew and then how it just slowed and wondered why we weren’t like that. Like deer get popped out and are able to walk but humans take around a whole year to get to stumbling around

@@efisgpr Did you not pass comprehensive reading?
They do not age faster, they age like dogs. Time doesn't pass faster merely because they are a dog. Their body is able to reach sexual maturity in less time, not because time itself ages dogs faster.

One *could* say dogs pass through the same stages of life quicker relative to, say, humans, but to outright say they "age faster" is a moronic oversimplification and wrong. An mere alteration to: "dogs bodies AGE FASTER non-linearly the older they get" is accurate and not defying physics.
Would you say an ant ages faster? No because it sounds weird... because it's wrong.
"Dog years" are merely a method of understanding more or less where a dog is along the path of life n the likely state of their body by putting in perspective. Not because a dog is actually 25 or whatever.
There is no "aging faster" or "aging slower" in this context. A less-than-alacritous approach to conveying how to adequately and properly use dog charts; and I don't accept saying the latter or former only because we've gone through a stage of simplifying everything.

There are, sadly they are usually overshadowed by the male dominated field
Small correction: this doesn't imply dogs age slower when they're old than humans do. You can infer "slower" and "faster" by the slope of the graph. Slope > 1 implies dogs age faster, and Slope < 1 implies humans age faster. Since the graph always has a slope > 1, a dog at 14 will age faster than a human at 70. The correct inference would be dogs always age faster than humans but get closer to the human rate of ageing as they get older :)
Omg I just realized this. Thats the perception of age. When you turned the chart it reminded me of how we perceive time as we age. Thats why time flies as we get older. We aren’t receiving as new stimuli as often as when were younger. This just hit me like a truck and maybe other people already realized this and I’m lagging behind but still.
I've never thought about it this way but it makes a lot of sense, since they grow in size really fast, which is a bummer since puppies are cuter.
Probably, couple of years back when I left my dog at dog shelter coz i thought he grew very very old.

Also, by breed/size is another age variable. There are some fillable forms online where you can get a better breakdown. Glad you're helping to disprove this myth!
Yes, quantifying aging is indeed the question. Also consider that humans are kept alive at the end of their life for much, much longer than dogs are. You miss your dog something fierce when it dies, but you let it die. For humans, we spend $$$$ on their healthcare when they are near the end of their life just to keep them alive for a few more miserable years. Glad I’m a cat.
They estimate it with maturity
My dog is 14, when we first got her she grew up fast and about 2-3 years ago she started showing signs of old age, luckily she hasn't been getting worse recently it's almost as if she is aging slower the older she gets, this explains alot
This reminds me that dogs probably see us as elves
