Puppy Blues: How Long They Last and What Helps

What are the puppy blues?

The puppy blues is the name owners give to a wave of anxiety, frustration and exhaustion in the weeks or months after a new dog comes home. It is not a clinical diagnosis. It is a pattern so common that people recognise it the moment someone names it.

It often sounds like this. You wanted this dog for a year. You read the books, bought the crate and booked puppy school. Now you are up at 2am in the backyard waiting for a wee, your hands are covered in tiny teeth marks, and you catch yourself thinking you have ruined your life. Then the guilt arrives for thinking it.

None of that means you chose the wrong dog. It means you are doing all of the work before the bond has had time to form, on very little sleep.

What did the research actually find?

Until recently there was almost nothing in the scientific literature about this, even though owners have used the phrase for years. In 2024 a Finnish research team (Aada Ståhl, Hannes Lohi and colleagues) published the first validated questionnaire for it, the puppy blues scale, in the Nature Portfolio journal npj Mental Health Research. You can read the full paper free on PubMed Central.

They built the scale from written accounts by owners who had struggled, then tested it on 1,801 responses from Finnish dog owners. A further group of 265 dogs was retested later, and 326 owners of one to two year old dogs rated both the puppy period and the present.

The headline finding: 45.1% of respondents reported significant negative feelings during their dog's puppyhood. For comparison, the paper notes that around 38% of women are thought to experience baby blues after giving birth. That is a comparison of how common the feelings are, not a claim that the two are the same thing.

One caveat matters for how much weight to put on the numbers. The sample was Finnish, about 92% of the owners were women, and people rated the puppy period from memory. Nobody has run the same study in Australia. Treat the direction of the findings as solid and the exact percentages as a strong signal rather than a fixed rule.

How long do puppy blues last?

Longer than most guides admit. Among owners in the study who reported significant negative feelings, only about one in five were through it within a month, and nearly half were still in it at six months or more.

If you are four months in and everyone told you it passes in a few weeks, that gap becomes its own source of distress. You conclude that something is wrong with you in particular. The data says otherwise: at four months you are squarely inside the normal range.

The better news sits right beside it. Owners of one to two year old dogs rated the present significantly lower than the puppy period on all three parts of the scale. The researchers also saw a slight fading of the bad memories over time: the further people got from puppyhood, the more kindly they remembered it. It ends. It just does not always end on the schedule you were promised.

What are the puppy blues made of?

The scale splits the puppy blues into three parts. They often arrive together, but one can dominate at a time.

• Anxiety (39% of the variance the scale explains). Worry about the puppy, about getting it wrong, about whether this was a mistake.
• Frustration (34%). Irritation at the chewing, the interruptions and the loss of your own time.
• Weariness (28%). Flat exhaustion, the sense of never catching up.

Anxiety being the biggest piece is useful to know. It suggests the thing that helps most is often not more effort. It is reassurance and good information, because many new owners run a constant background worry of “am I ruining this dog?”, and that worry costs more than the chores do.

What do owners struggle with most?

In the written accounts from owners who had struggled, these were the most common themes:

Sleep sits at the top, and it quietly drives the rest. Sleep loss shortens your fuse and makes ordinary problems feel unsolvable. If you can fix only one thing this week, fix your sleep, even if the puppy sleeps somewhere you had not planned or someone else takes a night.

Notice that feeling inadequate is the second most common theme, and that thinking about giving the puppy away came up too. If either thought has crossed your mind, you are in good company. Having the thought is not the same as acting on it.

Do adult rescue dogs bring the same blues?

Many adopters describe the same feelings with an adult dog, but the study measured puppy owners, so its figures describe puppyhood. With a rescue dog there is often an extra layer: you are also learning a history you do not fully know, and the dog in your house in week one is a stressed dog, not the dog you will end up with.

Australian rescues say this plainly. RSPCA South Australia says some dogs settle in a few days and others take anywhere from a few weeks to months, and advises skipping the beach and the dog park at first and limiting visitors. RSPCA WA recommends calm, predictable, low-pressure first weeks with a steady routine. Both point the same way as the research: judging the match in week one is judging it at its lowest point.

What actually helps?

1. Protect your sleep first. It is the top theme in the research and it makes everything else harder. Share night shifts, and put the puppy's bed where you can settle it quickly rather than where you planned.
2. Shrink the problem. A pen or a crate the puppy is happy in means it is not loose and needing constant watching, and you get real time off.
3. Lower the bar. A fed, safe, reasonably exercised puppy is a well-cared-for puppy this month. Perfect is not the standard.
4. Use reward-based training. The RSPCA Australia Knowledgebase supports positive reinforcement and says aversive methods should not be used. A good puppy school gives you a plan and a room full of people in the same boat.
5. Get time away. A walker, a daycare day, or a friend for an afternoon. Being able to leave is what stops the trapped feeling building.
6. Set a no-decisions date. Write a date six or eight weeks out on the fridge and agree with yourself to make no permanent choice before it. The worst week should not get the casting vote.
7. Say it out loud. Tell your vet, your rescue or a friend who has raised a dog. The isolation is a large part of the weight, and almost everyone who has done this has a version of your story.

When should you get help instead of waiting?

Ordinary overwhelm and doubt respond to time and the steps above. Some things do not, and waiting makes them harder.

• Aggression, growing fear or any risk to people in the house. Start with your vet, who can rule out pain or illness and refer you to a qualified behaviour professional. Choose someone who trains with rewards, in line with the RSPCA's guidance for new puppies.
• Physical signs in the dog. Pain and illness drive a lot of behaviour that looks like defiance. Never give a dog medicine from your own cupboard; let the vet decide.
• Your own mood. If low mood or anxiety lasts beyond a few weeks, feels heavier than “I am not sure about this dog”, or stops you functioning day to day, talk to your GP. That deserves support in its own right, separate from the dog.

What if you genuinely cannot keep the dog?

Give it a fair window first if you can do so safely, because the research is clear that most of this lifts. Before you decide, it helps to be honest about which kind of problem you have.

If your list sits on the left, give it the weeks. If it sits on the right, this is the responsible order, and there is no shame in any of it.

1. Go back to where the dog came from. Ring the rescue you adopted from, or the breeder you bought from, and read your adoption or sale contract. A rescue would far rather take a dog back, or help you place it, than lose track of it. Tell them early and honestly; the sooner they know, the better the landing they can arrange.
2. If they cannot help, rehome through a screened service. List the dog with photos, an honest description of its behaviour and a fee, and screen the people who reply. Our owner rehoming page exists for exactly this, and the dog stays with you until the right home is found. If you are renting and a pet rule is the problem, check our renting with pets guide first: some refusals can be challenged.
3. Never take the shortcuts. No unscreened “free to good home” post, no dumping, no handing a dog to a stranger in a car park. Every one of those can end badly for the dog.

The researchers raise the same point: they note that puppy blues, left unaddressed, may lead some owners to give up their dog. Asking for help early is what prevents that outcome, not what admits it.

Not adopted yet? How to lower the odds

If you are reading this before you bring a dog home, good. The puppy blues are not a reason to give up on a dog, but a few honest choices make them less likely and shorter.

• Test your time and budget honestly. Our adoption readiness check takes a few minutes and asks the questions people skip, and the dog cost calculator puts a number on the first year.
• Consider an adult dog. An adult rescue dog has a known size and temperament and has usually left teething and toilet training behind, which are the months that wear new owners down. Our guide to adopting a dog in Australia covers the steps and fees, and the senior dog guide makes the case for an older dog.
• Plan the first fortnight. Take time off if you can, line up help for the nights, and book puppy school before the puppy arrives.
• Ask the rescue about the dog's routine. Foster carers know how a dog sleeps, eats and copes alone. That is information a pet shop cannot give you.
