Stages of Labour in Dogs Explained: What to Expect

Stages of Labour in Dogs Explained

Learn the 3 stages of labour in dogs, what to expect during whelping, and when to seek veterinary help.

Stages of Labour in Dogs Explained: What to Expect

Understanding the stages of labour in dogs helps you prepare, recognise progress and respond appropriately if something doesn’t go to plan. While many dogs whelp without complications, knowing what is happening at each stage allows you to monitor with confidence and support your dog when needed.

For breeders, this knowledge forms the foundation for recognising normal labour and identifying when intervention may be required.

Stage One: Early Labour (Preparation Phase)

The first stage of labour is often the longest and can be easy to miss if you’re not watching closely.

This stage typically lasts between 6 to 12 hours, although it can extend up to 24 to 36 hours in some dogs. During this time, the cervix is dilating and the body is preparing for delivery.

Common signs include:

• Nesting behaviour
  
• Restlessness or pacing
  
• Panting or shivering
  
• Reduced appetite
  
• Seeking a quiet or secluded space

Contractions may not be clearly visible yet, but your dog is entering the early phase of labour.

If you’re unsure whether labour is about to begin, see our guide on signs your dog is about to whelp to help you recognise these early changes.

Stage Two: Active Labour (Delivery of Puppies)

Stage two is when puppies are delivered and is the most critical phase to monitor closely.

Contractions become strong and visible, and your dog will begin actively straining. The first puppy is usually delivered within 1 to 2 hours after strong contractions begin.

During this stage:

• Puppies are typically born every 20 to 60 minutes
  
• Short rest periods between puppies are normal
  
• Your dog may stand, lie down or reposition frequently
  
• She will often clean each puppy immediately after birth

Some dogs may take longer breaks between puppies, sometimes up to 2 hours, especially with larger litters. As long as your dog is comfortable and not actively straining without producing a puppy, this can still be within normal limits.

However, this is also the stage where problems are most likely to occur.

If labour does not progress as expected, or something doesn’t seem right, it’s important to understand normal vs abnormal whelping and when to intervene so you can act quickly if needed.

 

Stage Three: Passing the Placenta

Stage three involves the passing of the placenta and usually occurs shortly after each puppy is born.

In many cases, stage two and stage three overlap, with a placenta passed after each puppy. It’s normal for your dog to consume the placenta, although this is not essential and excessive consumption can sometimes lead to digestive upset.

Key points to watch:

• Each puppy should be followed by a placenta
  
• Retained placentas can cause complications
  
• Mild discharge is normal, but foul-smelling discharge is not
  

How Long Does Whelping Take?

The full whelping process varies depending on litter size and the individual dog.

As a general guide:

• Small litters may be completed within a few hours
  
• Larger litters can take several hours, sometimes longer
  
• Breaks between puppies are normal, but timing matters

Monitoring timing between puppies is one of the most important ways to assess whether labour is progressing normally.

When Things Don’t Follow the Expected Stages

While many dogs progress smoothly through all three stages, deviations can happen.

Labour may stall, contractions may weaken, or a puppy may not be delivered despite active straining. These situations require careful assessment.

Rather than guessing, it’s important to understand what falls outside normal expectations. Our guide on normal vs abnormal whelping explains when to intervene and when to seek veterinary support.

Preparing for Each Stage

Preparation before labour begins makes a significant difference once whelping starts.

Having your setup ready, including your whelping supplies and heating & critical care equipment, ensures you can focus on monitoring rather than scrambling for equipment.

Once puppies arrive, you’ll also need to be ready to support them with warmth and feeding if required.

After Labour: Immediate Care

Once all puppies are delivered, attention shifts quickly to stabilisation and monitoring.

Newborn puppies must be kept warm, as they cannot regulate their body temperature. Knowing how to warm a cold puppy safely is essential in the first hours after birth.

Feeding should begin soon after birth. Monitoring intake using a milk feeding calculation guide helps ensure each puppy is receiving adequate nutrition.

If any puppies appear weak or are not feeding well, early support using appropriate neonate puppy nutrition and feeding methods may be required.

Final Thoughts

Understanding the stages of labour in dogs gives you a clear framework for what to expect and how to respond throughout the whelping process. From early behavioural changes to active delivery and post-birth care, each stage plays an important role in the health of both the mother and her puppies.

If your dog shows signs of distress, labour isn’t progressing, or you’re unsure at any stage, it’s always best to check in with your veterinarian for guidance.
