Dog Labour and Whelping: What Is Normal and When to Call a Vet
この記事で
By Dr Duncan Houston
When your dog starts nesting and panting, knowing what to watch is more useful than hoping nature handles everything. Difficult labour can threaten both mother and puppies, and early contact gives the veterinary team more options.
Quick Answer
Whelping involves preparation of the birth canal, delivery of puppies and passage of placentas. Contact an emergency vet if strong straining continues for about 20 to 30 minutes without a puppy, a puppy appears stuck, or the mother becomes unwell. Green-black discharge before the first puppy and a pause of two hours when more puppies are expected also require immediate veterinary advice.
Make a plan before labour
Pregnancy is about 63 days from ovulation, but mating dates alone do not give an exact due date. Agree a monitoring plan with your vet, especially for a singleton, previous difficult birth or a breed at increased risk. Ask whether late-pregnancy imaging would help assess puppy numbers and delivery planning.
Prepare a quiet, clean whelping area, clean towels, an accurate scale and an adjustable safe heat source. Keep an unheated area available so the mother and puppies are not trapped against heat. Know which clinic can provide emergency surgery and how you will transport the whole family.
What do the stages look like?
During the first stage, the mother may be restless, pant, nest and refuse food without obvious abdominal pushing. A temperature drop may occur, but it is not reliable enough to decide that everything is safe. Contact your vet if early labour is prolonged or the expected progress does not happen.
Visible abdominal contractions mark the delivery stage. Placenta passage overlaps with puppy delivery, and a placenta may follow the next puppy rather than immediately. Record birth times and puppy details instead of relying on memory during a busy night.
When is this an emergency?
| Warning sign | Action |
|---|---|
| Strong pushing for 20 to 30 minutes without delivery, or a puppy lodged at the vulva | Call the emergency clinic and prepare to leave immediately. |
| Green-black discharge before the first puppy, heavy bleeding or foul discharge | Seek immediate veterinary assessment. |
| Two hours since the last puppy when more are expected | Call immediately for assessment, even if the mother is resting. |
| Collapse, severe pain, marked weakness, tremors or seizures | Emergency treatment now. |
These are contact thresholds, not instructions to wait until the clock runs out when something looks wrong.
Why can labour stall?
The uterus may fail to contract effectively, a puppy may be too large or incorrectly positioned, or the birth canal may be obstructed. Examination and imaging help distinguish these problems. Medication that increases contractions can be dangerous when an obstruction exists, so never give oxytocin or calcium without direct veterinary instructions.
Support the puppies safely
- Observe closely without crowding the mother or repeatedly moving her.
- If a newborn's face remains covered by membranes and the mother does not clear it, remove the membrane from the face promptly, gently dry the puppy and call for guidance if breathing is abnormal.
- Never swing a puppy to clear fluid and do not pull forcefully on a puppy or umbilical cord.
- Help warm, responsive puppies reach the mother to nurse. A cold, weak or non-nursing puppy needs urgent advice; do not force-feed.
- Record weights daily and arrange the mother's and puppies' post-birth examination with your vet.
Common mistakes and prevention
- Waiting hours through strong unsuccessful pushing.
- Assuming a quiet mother has finished without considering the expected litter count.
- Using unregulated direct heat or leaving puppies unattended beside a heating pad.
- Starting calcium supplements during pregnancy without advice.
Pre-breeding health screening, suitable nutrition and an agreed emergency plan reduce avoidable problems, although they cannot guarantee an uncomplicated birth.
Frequently asked questions
Can a puppy be born back feet first?
Yes, but a puppy that is not progressing needs veterinary help. Do not assume any visible presentation is safe to pull.
Must every placenta be counted?
Record what you see, but mothers may eat them. A missing count alone does not prove retention; illness or abnormal discharge needs examination.
Does a large litter mean surgery is inevitable?
No. Delivery decisions depend on the mother, puppies and progress, not litter size alone.
A prepared owner does not have to manage an obstetric emergency alone. Calling early is part of good whelping care.
