Okay. You’ve watched the nesting.
You’ve watched the panting.
You’ve probably watched her walk around the room approximately 400 times.
And, after spending the last few days analysing every change in behaviour, you’re now fairly confident...
This is actually happening.
Which usually leads immediately to the next question:
“Right. What do I do NOW?”
Because there can be quite a stretch between recognising that your dog is in labour and actually meeting puppy number one.
So, let’s talk about that bit.
Not delivering puppies. Not cords, placentas or what happens between puppies. We’ll cover the actual birth separately.
This is about Stage One labour in dogs, what it can look like, what you should be doing while you wait and how to prepare before your girl starts actively pushing.
The quick answer
If your dog appears to be in labour but isn’t visibly pushing yet, she may be in Stage One. Your job is usually to keep her environment calm, watch how things are progressing, give her access to water and supervised toilet breaks, make sure your whelping equipment and veterinary plan are ready, and seek veterinary advice promptly if something doesn’t seem right.
What Is Stage One Labour in Dogs?
Stage One is essentially your girl’s body getting everything ready for delivery.
Her uterus is beginning to contract and her cervix is dilating, but importantly, you generally won’t see the obvious abdominal pushing you’d associate with delivering a puppy.
Instead, what you see from the outside can look much less dramatic.
She might:
- Pant or breathe differently
- Pace and struggle to settle
- Nest, dig or repeatedly rearrange her bedding
- Tremble or shiver
- Lose interest in food
- Want you permanently attached to her side
- Decide she’d actually rather you disappeared altogether
- Keep changing position or moving between places
This is why breeders spend so much of Stage One thinking:
“Surely something should be happening by now?”
Something IS happening.
You just can’t see most of it yet.
How Long Does Stage One Labour Last in Dogs?
There isn’t a stopwatch-perfect length for Stage One. It can continue for several hours, and in some bitches it may last around 12 to 24 hours before obvious active straining begins.
Rather than watching the clock in isolation, look at the whole dog and how things are progressing.
Pay attention to changes such as:
- Her behaviour becoming more obviously labour-like
- The development of visible abdominal effort
- Any discharge
- Whether she remains comfortable and responsive
- Anything that makes you feel something isn’t right
If you’re concerned about the length of labour or your girl’s condition, contact your vet rather than relying on a generic timeline.
What Should I Do If My Dog Is in Labour but Not Pushing?
This is where we want you to resist the urge to become the world’s most enthusiastic labour assistant.
Your job at this stage is mostly to observe, prepare and keep things calm.
If she’s settled somewhere safe and suitable, let her settle.
Keep the environment quiet. Keep unnecessary visitors away. Give her access to water.
Offer opportunities to go outside to toilet, but supervise her closely. The last thing we want is your heavily pregnant girl disappearing behind a shrub because she’s decided THAT is where she’d prefer to have her puppies.
And start paying attention to how things are progressing.
You don’t need to document every breath she takes, but having a rough idea of when behaviours started changing can be really useful.
Get Your Whelping Kit Ready Before the First Puppy Arrives
Not when you can see the first puppy.
Now.
Stage One is your opportunity to do the final check while you’ve still got some thinking capacity left.
Having the right whelping kit matters more than having a box full of 63 random things somebody on Facebook once said you might need.
Make sure the essentials are clean, accessible and actually in the room.
Not upstairs.
Not “somewhere in that cupboard”.
And definitely not still sitting in an online basket.
Still getting your kit together?
Our CNC Whelping Bundle brings together practical nutritional support for the whelping and post-whelp period, so the things you intend to use are ready before you’re trying to make decisions in the middle of labour.
Explore the CNC Whelping BundleHave Your Whelping Plan Written Down Too
Equipment is only part of being prepared.
At 2am, when you’ve had no sleep and every noise your dog makes has you sitting bolt upright, a plan is much easier to follow than a vague memory of something you read three weeks ago.
Inside the Whelping World Support Club, members can use the A2C Birthing Plan Template to think through those decisions before labour day, alongside the Final Whelping Setup resource.
Being prepared doesn’t guarantee every whelp goes perfectly. It means you’re less likely to be trying to invent a plan while something is already happening.
Should I Keep Taking My Dog’s Temperature During Labour?
You can keep monitoring the information you’ve been using, but once you’ve established that labour appears to be underway, don’t become fixated on repeatedly taking her temperature.
A temperature change can be useful as part of recognising that whelping is approaching.
It isn’t something you need to chase throughout labour looking for another magic number.
The same applies to the other early signs.
At this point, progression becomes more useful than repeatedly checking whether the original signs are still there.
What If I’m STILL Not Sure My Dog Is Really in Labour?
This happens more often than you’d think.
You’ve got some of the signs. Her due date is close. She didn’t want breakfast, but then she wanted half your sandwich... and nothing feels particularly convincing.
Look at the bigger picture rather than one isolated sign.
If accurate timing is clinically important, or you’re concerned that your bitch may be at or beyond term, that’s something to discuss with your vet. They can advise whether examination or testing is appropriate for the dog in front of them.
If you’re not dealing with an emergency but you’re looking at your preparation, feeding, supplements or whelping plan thinking “I’m not actually sure I’ve got this right”, that’s exactly the sort of thing we can work through in a 1:1 breeding and nutrition coaching session.
Sometimes you don’t need another 47 Facebook opinions. You need somebody knowledgeable to look at your dog, your circumstances and your plan and help you get it right with confidence.
Is Panting Normal During Dog Labour?
Panting can be part of Stage One labour.
So can pacing, nesting, trembling and generally behaving as though she has absolutely no idea what she wants to do with herself.
This is why understanding Stage One beforehand is so useful.
If nobody has explained what this period can look like, several hours of panting and unsettled behaviour can feel like something is going terribly wrong.
Knowing what can be normal doesn’t mean ignoring your instincts or dismissing concerning changes.
It means you’re less likely to panic simply because labour doesn’t look how you imagined it would.
Want to learn this before you’re living it?
Inside the Whelping World Support Club, members can watch the Breeder Brief “Feeding For Pregnancy & Birthing Plans: What to Expect in Whelping”, as well as use the Final Whelping Setup and A2C Birthing Plan Template.
There are also regular live breeder Q&A calls, so you can ask about your own situation rather than trying to piece everything together from generic posts.
Explore the Whelping World Support ClubWhen Does Stage One Become Active Labour?
This is the change you’re waiting for.
During Stage One, uterine contractions are happening internally without the obvious abdominal pushing you’d associate with delivering a puppy.
As she moves into Stage Two, you’ll start to see visible abdominal contractions and active straining.
Things have changed.
We’re no longer simply watching a bitch preparing to give birth.
We’re moving towards puppy number one.
Know Which Vet You’re Calling BEFORE You Need Them
Don’t wait for a problem before deciding what you’ll do if one occurs.
Before whelping starts, you should know:
- Which veterinary practice you’re contacting during normal hours
- Where you’ll go if you need help out of hours
- How you’ll transport your girl if necessary
- How long the journey is likely to take
- Who else you may need to contact for practical support
If your girl seems significantly unwell, distressed or weak, you see concerning discharge or bleeding, she is actively straining without producing a puppy, or you’re simply concerned that something isn’t right, contact your vet promptly.
A blog, Facebook group or support club can help you prepare. None of them can assess the bitch sitting in front of you.
If something feels wrong, we would always rather you made the unnecessary vet phone call than delayed one you actually needed.
Should I Give My Dog Calcium During Labour?
Calcium is one of those things we’d much rather you had thought about before you need it.
But there’s an important distinction between:
having calcium ready for whelping
and
routinely supplementing calcium throughout pregnancy.
We don’t recommend giving calcium during pregnancy.
Our CNC WHELP WISE Natural Calcium is calcium citrate and is intended to form part of your bitch’s nutritional support from whelping onwards, particularly through lactation when calcium demands are naturally much greater.
That’s why we want it sitting in the whelping kit beforehand.
Not because we want you introducing calcium casually during pregnancy, but because once puppies have arrived you don’t want to discover that the nutritional support you intended to use is something you still need to source.
For larger dogs, fussier eaters or breeders who prefer a bulk format, we also have CNC CALCI-POWER Dissolvable Calcium.
If you’re unsure what calcium support is appropriate for your bitch, particularly if she has breed-specific risks, a large litter, previous problems or other health considerations, that’s something we can work through with you individually.
View CNC WHELP WISE Natural CalciumDon’t Forget That Whelping Nutrition Starts Before the Whelp
The whelp itself is one moment in a much bigger nutritional picture.
What she’s eating in the final part of pregnancy, whether she can comfortably manage the meal sizes you’re giving her, hydration, the timing of supplements, what you’re planning to feed once puppies arrive and how you’ll support lactation all matter.
Timing matters. Context matters. The rest of her diet matters.
That’s why our breeding nutrition advice isn’t simply “take this supplement”. We look at the dog, her diet, her stage and what you’re actually trying to support.
This Is Why We Prefer You to Prepare BEFORE Labour Day
We can explain Stage One to you now and it probably sounds perfectly manageable.
It’s rather different when it’s 2am.
You’ve had no sleep.
She’s panting.
She keeps changing beds.
You can’t remember whether she last went outside 20 minutes ago or two hours ago.
And every noise she makes causes you to sit bolt upright.
The aim isn’t to turn you into a vet. It’s to help you understand what you’re looking at, recognise when things are progressing normally and know when something needs somebody more qualified than the internet.
Inside the Whelping World Support Club, the resources most relevant to this stage include:
- Breeder Brief: Feeding For Pregnancy & Birthing Plans: What to Expect in Whelping
- Final Whelping Setup
- A2C Birthing Plan Template
- Live breeder Q&A calls
The point is that you don’t have to muddle through a pile of contradictory information and hope you’ve picked the right bits.
And Then... The First Puppy Is Coming
Once you can see proper abdominal contractions and active straining, you’re entering the next stage.
And that deserves its own guide.
Because then we need to talk about:
- What happens when the first puppy arrives
- The sac and membranes
- Umbilical cords
- Placentas
- What mum should do
- When you may need to help
- What happens between puppies
- When you need veterinary help
For now, if she’s in Stage One, your job isn’t to hurry her.
Keep things calm. Keep watching her. Be prepared. And know where you’re getting help if you need it.
