Small breed and toy breed dogs (such as Chihuahuas, Toy Poodles, Maltese, and Pomeranians) as well as brachycephalic breeds (such as French Bulldogs, Boston Terriers, and Pugs) have significantly higher birth risks than medium to large breed dogs due to their body structure.
Main risk factors:
- Relatively narrow pelvis: In toy breeds weighing 1–3 kg, the birth canal is small in absolute size, making obstructive dystocia (cephalopelvic disproportion/fetal head entrapment) common when puppy heads cannot pass through the pelvis
- Brachycephalic head structure: Brachycephalic breeds have large, flattened heads, making passage through the birth canal even more difficult
- Physical strain on small bodies: Prolonged labor efforts rapidly deplete the dam's strength and endurance
- Hypoglycemia risk: Toy breeds are prone to hypoglycemia during labor, which can lead to uterine inertia
As a breeder, when planning breeding, it is essential to understand these risks in advance and establish a coordination system with a veterinarian before delivery.
Normal Delivery Timeline
To detect dystocia early, you must be familiar with the progression of normal labor.
Stage 1 (Preparation): 6–24 hours
Temperature drops from 38.3–38.9°C to 37.7°C or below (the most reliable predictor of labor onset)
Stage 2 (Active Labor): 30 minutes to several hours (depending on litter size)
Strong abdominal contractions (straining) begin
The first puppy should be delivered within 30–60 minutes of straining beginning—this is normal
Subsequent puppies are typically delivered at 15–60 minute intervals
Puppies are delivered either still enclosed in the amniotic sac or after the sac ruptures
Stage 3 (Placental Expulsion): Immediately to a few minutes after each puppy
Placenta is expelled (one placenta per puppy should be delivered)
Retained placenta can cause endometritis
Early Detection Signs of Dystocia
If any of the following occur, contact your veterinarian immediately.
Sign
Urgency Level
No labor begins more than 24 hours after temperature drop
High
Strong straining for 30–60 minutes with no puppy delivery
High (Emergency)
Puppy visible in birth canal but not delivered after 30 minutes
High (Emergency)
Puppy partially delivered and stuck halfway
Critical (Immediate)
Dark green or black discharge without continued puppy delivery
High
Dam is weak, cannot stand, or is unconscious
Critical (Immediate)
More than 2 hours between puppies with no next puppy appearing
High
Non-Emergency Consultation Situations
Fewer puppies born than confirmed by ultrasound (after all placentas have been delivered)
Dam refuses to nurse or has no milk
Initial Response Actions Breeders Can Take
Labor Assistance (When Help Is Possible)
If a puppy is visible in the birth canal and slightly stuck, you can gently assist with clean hands or gloves.
Gently grasp the puppy with a clean glove or gauze
Pull in a gentle downward and backward arc, timed with the dam's contractions
Never pull too hard (excessive traction on the neck or front legs risks spinal injury)
If the puppy is not delivered after 3–4 contractions, contact your veterinarian
Neonatal Resuscitation (Newborn Puppies)
If a puppy is unresponsive or not crying immediately after birth:
Rub the entire puppy vigorously with a clean towel to stimulate breathing and maintain body temperature
Hold the head downward and gently clear fluid from the nose and mouth (light shaking is acceptable; never use forced expulsion techniques)
Give artificial respiration by gently blowing small breaths into the nostrils every 1–2 seconds, 2–3 times
Ligate the umbilical cord 2–3 cm from the puppy, then cut and disinfect with alcohol
Check the suckling reflex by inserting a finger in the mouth to confirm it sucks
If there is no response after 30 seconds to 1 minute of resuscitation, continue resuscitation efforts while calling your veterinarian.
Cesarean Section (CS) Decision Criteria
Cesarean section is performed in the following cases.
Planned Cesarean Section (Elective)
- History of previous dystocia or cesarean section
- Ultrasound or X-ray imaging shows too many or overly large fetuses
- Breeding of brachycephalic breeds such as French Bulldogs (often planned in advance)
Emergency Cesarean Section
- Signs of dystocia confirmed with no improvement within 30 minutes
- Significant depletion of dam's strength
- Fetal heart rate decline or cessation (confirmed by ultrasound)
It is essential to secure a veterinary hospital capable of emergency response before breeding. Since labor often begins at night, make a list of nearby animal hospitals with after-hours emergency services in advance.
Pre-Delivery Checklist for Breeders
Complete preparations 1–2 weeks before the estimated delivery date (58–65 days after breeding).
[ ] Share estimated delivery date with your regular veterinarian and confirm emergency contact information
[ ] Set up and clean the whelping box
[ ] Prepare clean towels, gauze, and disposable gloves
[ ] Prepare a rectal thermometer and digital scale for puppy monitoring
[ ] Practice puppy resuscitation (confirm procedures via YouTube, etc.)
[ ] Prepare heating pads or heat lamps (32–35°C) for warmth
[ ] X-ray imaging before delivery to confirm fetal count (appropriate at 34–45 days)
With proper preparation and veterinary coordination, small dog delivery can be safely managed. As a breeder, the most important factor is the speed of decision-making—calling your veterinarian as soon as you notice anything unusual.
