The answer
Partly, and the trainers tell families which part to expect. On film they split nervousness in two. 'There's two kinds of nervousness you have environmental nervousness and genetic nervousness.' The environmental part - something the dog met, or grew up with - can clear with exposure, sometimes completely: 'you can fix environmental nervousness sometimes 100% all the way to where they just look like they're not nervous anymore'. On one dog it is said to have gone 'around the one to two week period'. On another, placed on the environmental side at her first owner lesson, the trainer says at the handover: 'I I don't see any nerves with her at all anymore'. The genetic part 'takes a long time' and has to be managed: it cannot be punished away or reinforced away, and the route is 'open them up a ton get them to trust you and then teach them him how to manage the nerves'.
So the honest answer to 'will she be normal' is: the nerves that came from her history, often yes; the nerves that are simply her, no - but the goal for that part is not a dog who never gets nervous. It is a dog who does not lose herself when she does: 'if a dog doesn't know what to do the adrenaline hits they panic. They're not in there anymore.' One go-home trainer says it plainly of a dog who has come a long way: 'I think she'll always have, like, a level of, like, a little bit of nerves.' Simba's trainer gives the same prognosis by degree: with really bad nerves a dog may come to accept being touched and still never run up to people, while one with medium nerves can sometimes become the polar opposite (watch 28:03). Milo's puts the limit in human terms: training can make a person act extroverted but cannot change a personality 'rooted in genetics', and 'dogs are exactly the same' (watch 12:06).
How do they tell which is which? On film the evidence used is how fast the dog opens up - a dog who opens up fast reads as environmental, and 'typically when it's genetic nervousness it there is like a period that takes a lot longer' - and sometimes the history, which is often unknown. The trainers resist the story families reach for: one says that in most cases he has seen where people thought their dog had been abused, it was temperament, not abuse. Several readings are hedged: 'bad experience' or 'temperament plus experience'; 'his background' and 'potentially just his like general temperament'.
Three cautions come with the split. A quiet, compliant nervous dog is not necessarily a recovered one: 'it's very easy to make a nervous dog look opened up, when in reality you've repressed them'. A fear snap is not the same as a bite risk. And nerves are not an exemption: there is a level of panic no correction overrides, but locking up and avoiding are still 'against the rules'. Leaving the fear alone is not safe either - protecting a nervous dog from what scares him is said to make it worse as he gets older. And nerves that have cleared are kept clear, not cured once: the same dog's trainer tells her owner a week before go-home that she needs to be around people and dogs 'to like make sure her nerves don't creep back in', and gives an example: someone who got over a fear of spiders and then saw none for four months would find 'the nerves come back'.
Inferred, not stated: no trainer describes a test for the split in a dog with an unknown history beyond watching how fast the dog opens up. Luna's day-one reading is never revisited; Stormi's is the one early typing checked against the end (environmental at the first owner lesson, no nerves seen at go-home); Lola's moves from 'environmental' early on to 'a little bit of' each later, without comment.

What to do
Expect part of your dog's nervousness to fade with exposure and part to stay. Keep taking him to the things that worry him rather than avoiding them - and keep doing it after the nerves seem gone, because they can creep back. Judge progress by whether he stays with you and keeps functioning when nervous, not by whether he looks quiet. Do not assume he was abused, and do not treat a fear snap as aggression without your trainer's read.
What the trainers say
there's two kinds of nervousness you have environmental nervousness and genetic nervousness genetic is like i mean it's self-explanatory i mean it's genetic um and environmental is like maybe they grew up something made them nervous you can fix environmental nervousness sometimes 100% all the way to where they just look like they're not nervous anymore genetic nervousness takes a long time
she's got a little bit of genetic nervousness and environmental nervousness the environmental nervousness is pretty much gone that was pretty much gone i would say around the one to two week period but genetic nervousness is a lot more tricky because you do have to learn to manage it
If it's environmental, it's better, because sometimes they just go away. If it's genetic, then they do have to learn how to essentially get through all, power through all the noise in their head, essentially.
with the genetic nervousness you can't just like you can't just be like oh like i'll reinforce the nervousness out of them or something like that you generally just have to open them up a ton get them to trust you and then teach them him how to manage the nerves
there's some trainers that they'll repress the dog and he'll look like he's not nervous but in reality he's just like even more terrified they just made him scared to run away yeah which is not a real solution
you have two kinds of nerves you have environmental and genetic i think that's like pretty i mean i could break it down but i think it's explaining sorry right you know genetic you it's it's there no matter what environmental it can be like a product of the environment
So then the goal becomes how do you get it so when the dog gets nervous that they don't like become overcome by the nerves and you know lose themselves right cuz if a dog doesn't know what to do the adrenaline hits they panic. They're not in there anymore.
The big thing with a nervous dog is that it's very easy to make a nervous dog look opened up, when in reality you've repressed them and aren't managing it well. To get a nervous dog truly opened up, you have to not repress at all, because obviously repressing is a form of, you know, closing the dog up.
with her it's definitely for some reason or another environmental or like small very like I I don't see a lot of genetic nervousness cuz again she's opening up really fast and typically when it's genetic nervousness it there is like a period that takes a lot longer for the dog to open
marvin in 95 of cases that i've ever worked with where people thought their dog was abused
he was doing like the fear bitey thing not like because like i i draw a strict line he's not a bite risk he is a a fear snapper where he gets he was because he was so freaked out when he first came
But you got to learn even in that window like hey you can't lock up. You can't this goes for any nervous thought, right? You can't get skddish and just kind of be like I'm just going to avoid you. Doesn't allow it. It's uh it's against the rules.
somebody dog person whatever is really really nervous hey the last thing you want to do is confirm their fears and let them go with those fears as they get older no come on because then it only gets worse
I think she'll always have, like, a level of, like, a little bit of nerves.
I I don't see any nerves with her at all anymore
and then some dogs genetically like they're just personality is weary and nervous of people and they are always gonna be a little bit nervous and both are doable the only difference is environmental you just teach them like hey there's no reason to be scared and then they're not scared whereas a genetic one you teach them how to manage the nerves and it's like you're scared but you can't you gotta like calm down
she does need to be around other people and around other dogs randomly to like make sure her nerves don't creep back in
her nerves are doing really good, but if she doesn't have time to come out here, exercise, be around people and other dogs, eventually she'll start to get kind of sketched out again
to it depending on how strong the nerves are right like if the nerves are like really really bad then the dog might be okay with like you like coming up touching them whatever but there's some dogs are right they're never gonna like run up to people
How it looks, dog by dog
Lola
Lola is the dog the split is worked out on. On her first day the trainer says that in very bad cases nerves cannot be removed, only managed, but that he does not think she is one of those - and adds that he cannot promise, because she is a living animal, not a character he is writing. At go-home the goal for that part is stated: not a dog who is never nervous, but one who does not lose herself when she is. Her file also carries the quality check that keeps the split honest - a repressed nervous dog looks just like an opened-up one.
On film
Sometimes, in very, very, very, very, very bad cases, you cannot get rid of them, but you can teach the dog how to manage it. However, I don't think that Lola is going to be one of those
i can't promise that because it's a little you know it's it's not a it's not a made-up character i'm writing or uh it's a life form
with her it's definitely for some reason or another environmental or like small very like I I don't see a lot of genetic nervousness cuz again she's opening up really fast
she's got a little bit of genetic nervousness and environmental nervousness the environmental nervousness is pretty much gone
So then the goal becomes how do you get it so when the dog gets nervous that they don't like become overcome by the nerves and you know lose themselves right
Luna
Luna is typed in the first minute of her first outdoor session - 'more of a environmental kind of nervous, so I do think that we can fix her right on up' - and the theory is spelled out to her family five weeks later. Her file also separates the words: skittish is better than terrified; avoidant of people without being afraid of them; cautious is fine but hers was more than that; and skittish while handling pressure extremely well, which is what licensed a firm program. And it holds the limit and the standard ten seconds apart: no correction overrides a real flight impulse, and locking up and avoiding are still against the rules.
On film
she's a nervous case, um, which is, of course, why I'm with her, because she's, she's more of a environmental kind of nervous, so I do think that we can fix her right on up
the tail's not like too bad she's just a little skittish which is way better than the altar which which is actually like terrified is not what you want
but it already looks better than the first time out here she's fairly avoidant to people as a whole and not in terms of being like terrified she just really has no interest in them
so there's a difference between like skittish is in like nervousness and then skittish is in like if you come up to luna she's just a little cautious right cautious is fine but like her level was a little bit much
type of brake she is, she handles pressure really well. Even though she's a little skittish, she does handle the pressure extremely well.
and that of course being the e-collar. There's no amount of that with the e-collar that is going to override that.
Finn
Finn is the case on the other side of the fork. His nervousness is called genetic and given a route with three steps and no shortcut - open him up, earn his trust, then teach him to manage it - with both easy answers ruled out and the fake fix named: a trainer who represses the dog until he is too frightened to run. His snapping at first meeting is classified deliberately as a fear snap, not a bite risk. And the same fear at a hundred pounds is a different handling problem from the same fear in a small dog.
On film
with the genetic nervousness you can't just like you can't just be like oh like i'll reinforce the nervousness out of them
he was doing like the fear bitey thing not like because like i i draw a strict line he's not a bite risk he is a a fear snapper
This is as bad as Ozzie. The only difference between Finn and Ozzie is Ozzie's terrified like this but Ozzie's about this big right and Finn weighs 100 hundred pounds
Stormi
At Stormi's first owner lesson the trainer gives the split in brief and places her on the environmental side: something probably made her nervous, and she is nervous in new places. Genetic nerves, of the two, take a lot more work. Sniffing and exploring are read as signs the nerves are improving. The typing is checked at the end. A week before go-home the trainer tells the owner her nerves are doing really well but need upkeep: random time around people and other dogs, or they creep back - his example is a man who got over spiders and then went four months without seeing one. At the handover he says he sees no nerves in her at all any more, and restates the split for the owner: environmental nerves are taught away, genetic ones managed, and both are doable. The same lesson gives a nerves reason for a heel rule: don't heel-grind her, because it would crank up her nerves and she would lose the exposure she has been having.
On film
you have two kinds of nerves you have environmental and genetic
yeah because it's not really genetic genetic is of the two the one that takes a lot more work
this right here though is good i number one when a dog starts sniffing and like doing their thing that means like their nerves are a lot better because they're like willing to be open and explore
I I don't see any nerves with her at all anymore
and then some dogs genetically like they're just personality is weary and nervous of people and they are always gonna be a little bit nervous and both are doable the only difference is environmental you just teach them like hey there's no reason to be scared and then they're not scared whereas a genetic one you teach them how to manage the nerves and it's like you're scared but you can't you gotta like calm down
she does need to be around other people and around other dogs randomly to like make sure her nerves don't creep back in
So, yeah, so that's the don't heel grind because for her, it would probably crank up her nerves, right?
Marvin (Giant Schnauzer)
At go-home Marvin's family is told that in most cases the trainer has seen where people believed their dog had been abused, it was not abuse but a submissive temperament - dogs who were treated kindly their whole lives.
On film
marvin in 95 of cases that i've ever worked with where people thought their dog was abused
that's how it happened like it's like a submissive aspect i guess yeah they're just like that
Egg
Egg's flinch is attributed to both at once - his background and his general temperament - and the trainer does not choose.
On film
um probably has something to do with his background uh and potentially just his like general temperament
Poseidon
The owner says Poseidon cowered from a shoe and a rag he has never been hit with. The trainer's answer keeps both readings open: bad experience, or temperament plus experience.
On film
these things so why are you that can happen if they've had some bad experience and it can also be temperament plus experience
Ozzy
Ozzy's family is given the case for intervening: a very nervous dog whose fears are confirmed gets worse as he gets older, and taking him only where there are no people removes the problems but makes them worse when people do appear.
On film
somebody dog person whatever is really really nervous hey the last thing you want to do is confirm their fears and let them go with those fears as they get older
idea of like okay well my dog doesn't like people so I'm gonna make sure I take him to a place where there's no people sure you get rid of all the problems but you actually make the problems worse for when people are there
Phoebe
At Phoebe's go-home Kelton sets the expectation plainly: some level of nerves will always be there, naturally, and she may still be unsure of people when she first meets them.
On film
I think she'll always have, like, a level of, like, a little bit of nerves.
It, like, just is there, like, naturally.
Louie
Louie's fear is never typed genetic or environmental; it is given a shape instead. A trainer notes he reacts when he feels confined, and says Christian noted the same. His receiving owner, speaking Spanish, arrives at the same shape independently: the dog does not like being cornered, and bites only when he is afraid.
On film
he was definitely a lot more reactive than he felt confined and Christian's noted that as well that's when he's really shown some reactivity
es que esto solo muerde cuando tiene miedo yo de ver este perro yo digo ese
Milo
At a Milo lesson (published 31 Mar 2026) the trainer explains the limit with a person: reinforcement and punishment could make someone act extroverted, but could not change a fundamental part of their personality, because that is rooted in genetics - and dogs are exactly the same, so each dog's personality sets rough limits on what training can do.
On film
and positive reinforcement and like you know create you as a like i couldn't change fundamental
aspects of your personality because those things are rooted in genetics so I
was outwardly extroverted but that wouldn't change you being extroverted right so dogs are exactly
Simba
On a store outing with Simba the trainer gives the prognosis by degree: socialisation works the same way it worked on his own fear of dogs, but how far it goes depends on how strong the nerves are. A dog with really bad nerves may come to accept being touched and still never run up to people; a dog with medium nerves can sometimes end up the polar opposite, enjoying it.
On film
to it depending on how strong the nerves are right like if the nerves are like really really bad
some dogs are right they're never gonna like run up to people like this dude here however if you
have a dog that maybe has like medium level nerves and you go to socialization right you can get them
to a point sometimes where it's almost like a complete just like you know polar opposite um
Why it works
The stated mechanism is about what a cause implies for treatment. Environmental nerves are something the dog learned about the world, so exposure can undo them - 'sometimes they just go away' (watch 04:39), on one dog by one to two weeks (watch 00:47). Genetic nerves are 'there no matter what' (watch 13:39): the two obvious levers - punishment and reinforcement - do not reach them (watch 05:03), and what is left is coping, 'power through all the noise in their head' (watch 04:39). What makes coping possible, in one trainer's account, is that nerves are distraction rather than incapacity: 'when you're nervous, you are physically capable of doing everything that you usually are' (watch 03:41). The limit is stated by the same handler who holds the standard: past a certain level the impulse to run cannot be corrected away (watch 28:56), but locking up and avoiding are still not allowed (29:10). The speed of opening up is the only diagnostic used on film (watch 02:14). A maintenance condition is attached to the environmental side: nerves that have gone 'come back' without exposure (watch 05:49, 06:03), and the same trainer gives that as the reason not to heel-grind a nervous dog - it would crank up her nerves and take away the exposure she has been having (watch 44:56, 45:08). Inferred, not stated: whether 'genetic' means a ceiling on the outcome or only on the time it takes - one statement says 'takes a long time', another 'you do have to learn to manage it'.
On film
nerves are distractions, right? They're high-level distractions, right? Because when you're nervous, you are physically capable of doing everything that you usually are.
and that of course being the e-collar. There's no amount of that with the e-collar that is going to override that.
her nerves are doing really good, but if she doesn't have time to come out here, exercise, be around people and other dogs, eventually she'll start to get kind of sketched out again
So, yeah, so that's the don't heel grind because for her, it would probably crank up her nerves, right?
And she's not having that exposure like she did have.
Where the trainers differ
Can nerves be typed on the first day, or only by watching how fast the dog opens up?
One view
Typed in the first minute of the first session, before a command is asked, and the plan follows from it.
On film
she's a nervous case, um, which is, of course, why I'm with her, because she's, she's more of a environmental kind of nervous, so I do think that we can fix her right on up
Another view
Read from the rate at which the dog opens up, which cannot be known at intake.
On film
with her it's definitely for some reason or another environmental or like small very like I I don't see a lot of genetic nervousness cuz again she's opening up really fast
Is the genetic part a ceiling on the outcome or only on the speed?
One view
A ceiling: it is managed for life; she will always have some nerves.
On film
she's got a little bit of genetic nervousness and environmental nervousness the environmental nervousness is pretty much gone that was pretty much gone i would say around the one to two week period but genetic nervousness is a lot more tricky because you do have to learn to manage it
I think she'll always have, like, a level of, like, a little bit of nerves.
and then some dogs genetically like they're just personality is weary and nervous of people and they are always gonna be a little bit nervous and both are doable the only difference is environmental you just teach them like hey there's no reason to be scared and then they're not scared whereas a genetic one you teach them how to manage the nerves and it's like you're scared but you can't you gotta like calm down
Another view
The speed: genetic nervousness 'takes a long time' and 'a lot more work'.
On film
there's two kinds of nervousness you have environmental nervousness and genetic nervousness
yeah because it's not really genetic genetic is of the two the one that takes a lot more work
Is a nervous dog's avoidance exempt from the rules?
One view
The impulse is real and nothing overrides it - said by the handler holding the collar, about his own tool.
On film
and that of course being the e-collar. There's no amount of that with the e-collar that is going to override that.
Another view
And still the standard applies inside the nervous moment: locking up and avoiding are against the rules.
On film
But you got to learn even in that window like hey you can't lock up.
How to read it
Both said by one handler seconds apart; the record never says how a handler decides in the moment which applies.
Something must have happened to him - history or temperament?
One view
Usually temperament: most dogs owners believed were abused were not.
On film
marvin in 95 of cases that i've ever worked with where people thought their dog was abused
Another view
Often both, or unknown: 'bad experience' or 'temperament plus experience'; 'his background' and 'his general temperament'.
On film
these things so why are you that can happen if they've had some bad experience and it can also be temperament plus experience
um probably has something to do with his background uh and potentially just his like general temperament
Common owner mistakes
- Taking a quiet, compliant nervous dog as a recovered one.
On film
The big thing with a nervous dog is that it's very easy to make a nervous dog look opened up, when in reality you've repressed them and aren't managing it well.
Lola · Watch at 6:44 ↗ there's some trainers that they'll repress the dog and he'll look like he's not nervous but in reality he's just like even more terrified
Finn · Watch at 5:41 ↗ - Protecting the dog from everything that frightens him, so the fear grows.
On film
idea of like okay well my dog doesn't like people so I'm gonna make sure I take him to a place where there's no people
Ozzy · Watch at 18:55 ↗ - Reading a fear snap as aggression and treating the dog as dangerous.
On film
he was doing like the fear bitey thing not like because like i i draw a strict line he's not a bite risk
Finn · Watch at 11:25 ↗ - Assuming the nerves mean the dog was abused.
On film
marvin in 95 of cases that i've ever worked with where people thought their dog was abused
Marvin (Giant Schnauzer) · Watch at 12:35 ↗ - Expecting the residual nerves to go, and reading their return as failure.
On film
So then the goal becomes how do you get it so when the dog gets nervous that they don't like become overcome by the nerves
Lola · Watch at 1:08 ↗ - Treating a nervous dog as unable to do anything, and asking for nothing.
On film
nerves are distractions, right? They're high-level distractions, right?
Lola · Watch at 3:41 ↗
Questions owners ask
Will my nervous dog ever be a normal dog?
Partly. The nervousness that came from experience can often clear, sometimes completely; the part that is temperament is managed, not removed. The goal for that part is a dog who stays present when nervous, not one who never feels it. One dog typed environmental at her first owner lesson showed no nerves at all by go-home - with the condition that she keeps meeting people and dogs so the nerves don't creep back.
On film
there's two kinds of nervousness you have environmental nervousness and genetic nervousness
So then the goal becomes how do you get it so when the dog gets nervous that they don't like become overcome by the nerves
I I don't see any nerves with her at all anymore
she does need to be around other people and around other dogs randomly to like make sure her nerves don't creep back in
How can you tell which kind my dog has?
On film, mainly by how fast the dog opens up: fast reads as environmental, and genetic nerves take much longer. Sometimes a trainer calls it early; often the reading is 'a bit of both'. No other test is described.
On film
with her it's definitely for some reason or another environmental or like small very like I I don't see a lot of genetic nervousness cuz again she's opening up really fast
Something must have happened to her. Was she abused?
Not necessarily. One trainer says that in most cases he has seen where families believed their dog was abused, it was temperament. Others keep both open - bad experience, or temperament plus experience.
On film
marvin in 95 of cases that i've ever worked with where people thought their dog was abused
these things so why are you that can happen if they've had some bad experience and it can also be temperament plus experience
He snapped at someone. Is he dangerous?
The trainers draw a line between a fear snap and a bite risk. A very frightened dog snapping at first meeting is classified as a fear snapper, and the practical question becomes size and handling rather than danger.
On film
he was doing like the fear bitey thing not like because like i i draw a strict line he's not a bite risk he is a a fear snapper
Shouldn't you go easy on a nervous dog?
Not by exempting her. Nerves are treated as a distraction, not an incapacity; there is a level of panic that nothing overrides, but locking up and avoiding are still not allowed. And a nervous dog kept away from what scares her gets worse. Exposure is the point even in obedience: one trainer tells an owner not to heel-grind her nervous dog, because it would crank up her nerves and cut the exposure she has been having.
On film
But you got to learn even in that window like hey you can't lock up.
somebody dog person whatever is really really nervous hey the last thing you want to do is confirm their fears
So, yeah, so that's the don't heel grind because for her, it would probably crank up her nerves, right?
The lesson
The goal
An owner can say which part of their dog's nervousness is expected to clear, which is expected to stay, and what 'coping' looks like for the part that stays.
Learn first
The drill
Not a drill on film, but a reading: watch how fast the dog opens up in new places (sniffing, exploring); separate skittish from terrified, avoidant from afraid, cautious from too much; and check a quiet dog for repression rather than recovery.
Watch out for
- Expecting all nerves to go.
- Mistaking repression for recovery.
- Avoiding every trigger.
Check yourself
When your dog is nervous now, does he still respond to you?
