# Puppy Separation Anxiety: Normal Crying vs a Real Problem

Many puppies cry when first left alone. How to tell normal protest from separation anxiety, what to do at night and on short absences, and when to get help.

Many puppies cry when they are first left alone, and that is normal at first. Then watch what happens next: does your puppy settle, sleep and eat, or does the distress build? For [what separation anxiety is, and what it is not](/blog/dog-separation-anxiety), see our complete guide.

> **Key Takeaways**
> - Crying when first left alone is expected: a new puppy has probably never been on its own (Dogs Trust).
> - A puppy that settles, sleeps and eats is adjusting. Crying that builds, or comes with pacing, drooling or scratching at the door, needs a closer look (ASPCA, Dogs Trust).
> - Crying is not the only sign. In the Generation Pup study, owners of 145 six-month-old puppies reported pacing when alone about twice as often as whining (Dale 2024). Film an absence.
> - Build time alone in steps small enough that your puppy stays calm. If it cries, shrink the step. Do not leave it to cry it out (RSPCA, Dogs Trust).
> - When distress continues once needs are met and you have slowed down, Dogs Trust advises an accredited behaviorist via a vet referral. In the US, the ASPCA names a board-certified veterinary behaviorist or a certified applied animal behaviorist.

## Why puppies cry when you leave

A puppy is a young social animal recently taken from its mother and litter. Being alone is new, and crying is the expected response.

A narrative systematic review of canine socialization places the socialization period at 3 to 12 weeks. It notes that puppies usually go to new homes at 8 weeks, although "abruptly separating puppies at this age may cause acute stress" ([McEvoy et al., 2022](https://pmc.ncbi.nlm.nih.gov/articles/PMC9655304/)). Among the 145 puppies analyzed in the UK and Ireland Generation Pup study, the median age at acquisition, excluding homebred puppies, was 58 days ([Dale et al., 2024](https://pmc.ncbi.nlm.nih.gov/articles/PMC11655275/)).

Dogs Trust puts it practically: "Leaving them straight away could be very scary for them as they probably haven't been on their own before." It suggests taking time off work to help your puppy settle in ([Dogs Trust](https://www.dogstrust.org.uk/dog-advice/puppy/new-home)).

The crying is a call for company. In a 1977 experiment with 24 puppies aged 4 to 8 weeks, contact with a person reduced separation distress calls most, followed by another dog, then toys, then food ([Pettijohn et al., 1977](https://doi.org/10.1002/dev.420100413), abstract).

## Normal crying or a real problem: how to tell

Volume tells you little. Watch three things: whether the puppy settles and eats, whether other signs come with the crying, and whether it continues once basic needs are met.

First rule out reasons that have nothing to do with separation: a full bladder, teething, frustration at a gate when it can see you, or overtiredness. Dogs Trust notes that a sudden burst of "zoomies" often means a puppy needs sleep ([Dogs Trust, First night](https://www.dogstrust.org.uk/dog-advice/puppy/first-night)).

| What you see | Usually normal | Worth a closer look |
|---|---|---|
| Crying after you leave | Fades, and the puppy then sleeps and eats what you left | Builds or comes in waves, and food is left untouched |
| Other signs | Only the voice | Also pacing, panting, drooling, or damage at doors and windows |
| When it whines | Also when you are there, to get attention | Only just before you leave or while you are away |
| Chewing and damage | Happens when you are home too | Mostly at the exit, and only when alone |
| Puddles | House-training is not finished, so accidents happen with you home too | Only when alone, in a puppy that is otherwise clean |
| At night | Settles once toilet, tiredness and sleeping near you are sorted | Continues after a toilet break and a slower move away |

Where the table rows come from:

- **Whining and other signs.** The ASPCA says a dog that "only whines just before you leave or during your absence" may have separation anxiety. Such a dog "will usually display at least one other symptom" such as pacing, panting, excessive drooling or destruction around doors ([ASPCA, Whining](https://www.aspca.org/pet-care/dog-care/common-dog-behavior-issues/whining)).
- **Chewing and puddles.** "Many young dogs engage in destructive chewing or digging while their guardians are home as well as when they're away", and soiling in the guardian's presence probably isn't separation anxiety ([ASPCA, Separation Anxiety](https://www.aspca.org/pet-care/dog-care/common-dog-behavior-issues/separation-anxiety)).
- **Food.** While settling in, a stressed puppy "may have a lack of appetite". Eating and resting in a relaxed position are signs of comfort ([Dogs Trust](https://www.dogstrust.org.uk/dog-advice/puppy/new-home)). The night row is covered below.

Crying that fades into real rest, with the food eaten, is [a short protest that settles into sleep](/blog/dog-howls-when-left-alone-then-stops). Damage spread around the room with the food gone needs a closer read, because [boredom, frustration and distress look different](/blog/why-does-my-dog-bark-when-i-leave) on camera.

## Quiet signs are easy to miss: film one absence

In Generation Pup, owners of 145 six-month-old puppies reported what their dogs did only when left alone. The most common signs were quiet ones. Pacing came first, at 14.5%, then whining at 7.6% and spinning at 6.9%. Howling (1.4%) and barking (0.7%) were near the bottom ([Dale et al., 2024](https://pmc.ncbi.nlm.nih.gov/articles/PMC11655275/)).

Two caveats. The 145 puppies were a case/control subsample of a 1,987-puppy cohort, so the shares describe that subsample. Of those, 46.9% met the study's definition of separation-related behavior (see [why the 46.9% puppy figure needs a caveat](/blog/how-common-is-separation-anxiety-in-dogs)). And one question asked about behavior on the owner's return, so some pacing may have happened after the door opened. The authors still found it "notable that the most commonly reported SRBs here included covert repetitive behaviours (pacing and spinning)".

A loud puppy can be coping and a quiet one can be struggling. The RSPCA recommends that all owners video their dog when it is left alone from time to time. The aim is "just to make sure that they're not showing a 'hidden' sign of distress, such as trembling, pacing about or whining" ([RSPCA, Left alone](https://www.rspca.org.uk/adviceandwelfare/pets/dogs/training/leftalone)). Here is [how to film one absence and read the footage](/blog/dog-separation-anxiety-camera).

## Nights: where your puppy sleeps and what to do when it cries

Start with your puppy sleeping close to you and move it further away gradually. If it cries, go back a step.

Dogs Trust describes two ways. Either start with the puppy's bed in your bedroom and "slowly move it further away every few nights", or put the bed where you want it long term and have a sleepover near it, then gradually move yourself away. Expect to get up for toilet breaks, and "just go at your puppy's pace" ([Dogs Trust, First night](https://www.dogstrust.org.uk/dog-advice/puppy/first-night)).

On crates, Dogs Trust is direct: "You should avoid shutting your puppy in their crate at night." If the puppy cries, "go back to sleeping in the same room and move the bed away even more slowly than before" ([Dogs Trust](https://www.dogstrust.org.uk/dog-advice/puppy/new-home)).

The research can look like it says the opposite. Generation Pup linked two night factors to less separation-related behavior at six months: being restricted to a crate or a room overnight at up to 16 weeks, and sleeping at least nine hours a night at that age ([Dale et al., 2024](https://pmc.ncbi.nlm.nih.gov/articles/PMC11655275/)). The link is correlational, from a small sample, and the authors warn that some exploratory results may be false positives.

The practical reading: give your puppy an enclosed place to sleep, which can be a room, and enough sleep. If you use a crate, watch your puppy during crate training and in the crate while you are home. The ASPCA says that if a dog shows "heavy panting, excessive salivation, frantic escape attempts, persistent howling or barking" in the crate, "crate confinement isn't the best option", and suggests one room behind a baby gate instead ([ASPCA](https://www.aspca.org/pet-care/dog-care/common-dog-behavior-issues/separation-anxiety)). For older dogs, see crate or gated room: how to decide.

## Teaching time alone at puppy age

Keep absences short, boring and frequent while your puppy is calm, and make the step smaller when it is not.

Three sources agree on the method:

- **AVSAB**: "Time must be scheduled for puppies to play alone with their favorite toys", which "may help to prevent problems of over attachment to the owners" ([AVSAB](https://avsab.org/wp-content/uploads/2018/03/Puppy_Socialization_Position_Statement_Download_-_10-3-14.pdf)).
- **VCA** (veterinary behaviorists Debra Horwitz and Gary Landsberg): "Puppies need to learn how to have alone time and amuse themselves with their toys", and "make sure that you only get him when he is quietly playing" ([VCA](https://vcahospitals.com/know-your-pet/separation-anxiety-in-dogs)).
- **Dogs Trust**: "build up time apart very gradually and associate it with something positive, like a long-lasting treat", and "shorten the time left if they show any signs of anxiety" ([Dogs Trust, Time alone](https://www.dogstrust.org.uk/dog-advice/training/home/time-alone)).

### How long can a puppy be left alone?

Minutes at first, and far less than the four-hour maximum the RSPCA gives for dogs: "for puppies much less" ([RSPCA](https://www.rspca.org.uk/adviceandwelfare/pets/dogs/behaviour/separationrelatedbehaviour)). No organization cited here gives a number of hours for puppies. Dogs Trust says puppies "shouldn't be left on their own for very long at all". The right length is whatever your puppy handles calmly.

### Ignore the crying, or go back?

For attention-seeking whining, the ASPCA says to "reward your dog for being quiet". The RSPCA says dogs and puppies left to "cry it out" "will only learn that being alone is terrifying" ([RSPCA](https://www.rspca.org.uk/adviceandwelfare/pets/dogs/behaviour/separationrelatedbehaviour)). Both fit once you separate two situations:

- **Distress when alone** (crying that builds, other signs, food untouched): make the step smaller. Shorter absence, bed closer, slower pace.
- **Attention whining while you are home**, once the puppy's needs are met: reward quiet instead. As the ASPCA puts it, "Teach your dog that she must always be quiet before receiving your attention."

### Socialization starts before you bring the puppy home

AVSAB describes the first three months as the most important socialization period and says continuing varied experiences through the first year "is also helpful in preventing separation-related behavior". Some of that window falls before you bring the puppy home. A 2017 study used six litters at the breeding facility of a large UK assistance-dog organization, comparing a new socialization program from birth to six weeks with the standard one. The new-program puppies scored better on a six-week assessment. At eight months, their handlers' questionnaire rated their separation-related behavior more favourably ([Vaterlaws-Whiteside & Hartmann, 2017](https://doi.org/10.1016/j.applanim.2017.08.003), abstract). McEvoy's review reports the groups as 19 and 14 puppies ([McEvoy et al., 2022](https://pmc.ncbi.nlm.nih.gov/articles/PMC9655304/)). You cannot repeat that breeder work yourself. At home, keep building calm time alone.

Does your puppy already show signs from the "Worth a closer look" column? Do not wait. [Start at week one of the protocol](/blog/how-to-train-a-dog-to-be-alone): departure cues first, then seconds, then minutes.

## Coming home: keep it calm, never punish

Come home quietly, and never punish your puppy for a mess you find.

Reactions on return showed up in Generation Pup. Puppies whose owners responded to "bad" behavior on their return by fussing over them (greeting, stroking, cuddling, playing) were more likely to show separation-related behavior at six months ([Dale et al., 2024](https://pmc.ncbi.nlm.nih.gov/articles/PMC11655275/)). So were puppies whose owners used more aversive techniques in general. The finding concerns reactions to a mess, and it may run the other way: owners of anxious puppies may simply fuss more.

Some owners punish instead. In the Royal Veterinary College's Pandemic Puppies cohort, 285 owners reported how they responded when they came home to signs of separation-related behavior. Of these, 59.2% ignored it, and 9.2% told their dog off or physically punished it ([Brand et al., 2024](https://pmc.ncbi.nlm.nih.gov/articles/PMC10812580/)).

The RSPCA explains why punishment backfires: "Even if you take your dog to 'the scene of the crime', they won't be able to associate your anger with their behaviour hours earlier." The dog, it adds, "will simply become more anxious the next time you go out". The "guilty" look (head low, ears back, body made small) is typical of dogs that have been told off before ([RSPCA, Left alone](https://www.rspca.org.uk/adviceandwelfare/pets/dogs/training/leftalone)).

Lopaw builds time alone in small steps: it records each session and sets the next one from your puppy's own threshold.

## When a puppy needs more help

See your vet if distress continues after needs are met and you have slowed down. Dogs Trust says: "If they still cry or appear distressed, they may be struggling with separation anxiety. If this is the case, it's best to get in touch with an accredited behaviourist via a vet referral" ([Dogs Trust](https://www.dogstrust.org.uk/dog-advice/puppy/new-home)). In the US, the ASPCA suggests a board-certified veterinary behaviorist (Dip ACVB) or a Certified Applied Animal Behaviorist ([ASPCA](https://www.aspca.org/pet-care/dog-care/common-dog-behavior-issues/separation-anxiety)). Medication is a question for your vet.

If your puppy came from a shelter, [a newly adopted dog's first week has its own rules](/blog/rescue-dog-first-week-alone), including when to get help early.

Will your puppy grow out of it? In 978 guide-dog puppies at one US organization, separation-related problems were less likely at 12 months than at 6 on average ([Serpell & Duffy, 2016](https://pmc.ncbi.nlm.nih.gov/articles/PMC4916180/)). That does not predict your puppy. See [whether puppies grow out of it, and what the follow-up studies show](/blog/can-dogs-grow-out-of-separation-anxiety). The first steps are the same either way. If you need outside help, here is [what professional help costs](/blog/separation-anxiety-dog-trainer-cost).

## FAQ

**Is it normal for a puppy to cry when left alone?**
Yes, especially in the first days, because a new puppy has probably never been on its own (Dogs Trust). Watch whether the crying fades into sleep and whether the puppy eats what you left.

**Should I ignore my puppy's crying?**
If your puppy is distressed when alone, do not leave it to cry it out (RSPCA). Make the step smaller instead (Dogs Trust). When it whines for attention while you are there and its needs are met, reward quiet (ASPCA).

**Should my puppy sleep in a crate?**
Not necessarily. Being restricted to a crate or a room overnight, and getting enough sleep, were linked to a lower chance of separation-related behavior at six months, but the link is correlational (Dale 2024). Dogs Trust advises against shutting a puppy in a crate at night: start with its bed near you and move it away gradually.

**How long can I leave a puppy alone?**
Much less than the four-hour maximum the RSPCA gives for dogs. Build up from minutes and shorten the time at any sign of anxiety (Dogs Trust).
