Complete Guide: Bitch in Late Pregnancy & Post-Parturition Care

PART 1: PRE-WHELPING CARE (4–5 Days Before Parturition)

1. Nesting Box / Whelping Box Preparation

• Set up the whelping box at least 1 week before the due date so the bitch can acclimatize to it.
• Box dimensions: large enough for the bitch to stretch out fully, with sides high enough to keep puppies in but low enough for the dam to step over.
• Line with newspaper (easy disposal) under clean, dry towels or vetbed fleece (non-slip, washable, warm).
• Place in a quiet, warm, draft-free room — ideally where the bitch feels safe and familiar.
• Maintain ambient temperature: 29–32°C (84–90°F) in the whelping area initially for neonates.

2. Temperature Monitoring (Critical Sign)

• Take the bitch's rectal temperature twice daily starting 7–10 days before the due date.
• Normal canine rectal temp: 38.3–39.2°C (101–102.5°F)
• Pre-whelping drop: 12–24 hours before labor, temperature drops to <37.8°C (100°F), often as low as 36.7°C (98°F) — this is the most reliable sign of imminent whelping.
• Record every reading in a log to catch the drop.

3. Nutritional Management

• Feed a high-quality, energy-dense diet (premium puppy food or a diet formulated for pregnancy/lactation).
• In the last week, the enlarged uterus compresses the stomach — feed smaller, more frequent meals (3–4×/day) rather than two large meals.
• Ensure constant access to fresh water — hydration is critical in late gestation.
• Do NOT supplement calcium (calcium carbonate or milk) during late pregnancy — this suppresses parathyroid hormone (PTH) and increases the risk of eclampsia (hypocalcemia/milk fever) during lactation. Calcium should only come from the balanced diet.
• Avoid high-fat treats that could cause GI upset close to whelping.

4. Veterinary Check / Pre-Whelping Assessment

• Schedule a pre-whelping vet check 1 week before the due date.
• Confirm litter size via X-ray at day 55–58 of pregnancy (puppies' skeletal mineralization is visible). This is essential — you need to know how many puppies to expect so you can recognize when whelping is complete.
• Ultrasound can be used earlier to confirm fetal viability and heartbeats.
• Discuss the owner's emergency plan: nearest 24-hour veterinary emergency clinic, vet's after-hours contact.

5. Hygiene and Grooming

• Clip the hair around the vulva, perineum, and mammary glands (especially in long-haired breeds) to keep the area clean and facilitate nursing.
• Gently clean the mammary glands with warm water. Do not use antiseptics.
• Check for any vaginal discharge — a small amount of clear or slightly blood-tinged mucus is normal; foul-smelling, bright green (before a puppy), or purulent discharge requires immediate veterinary attention.

6. Supplies to Have Ready

PART 2: THE THREE STAGES OF LABOR

Stage 1 (6–12 hours, up to 24 hours in first-time bitches)

• Uterine contractions begin but are not yet visible externally.
• Signs: restlessness, panting, nesting, shivering, anorexia, vomiting, seeking seclusion.
• Bitch may refuse food. This is normal.
• Keep environment quiet, minimize visitors and stress.

Stage 2 (Active delivery)

• Visible abdominal straining begins.
• Each puppy normally arrives within 1–2 hours of strong visible contractions.
• Normal inter-puppy interval: 15 minutes to 2 hours. Up to 4 hours is acceptable if the bitch is not distressing.
• Call your vet immediately if:
  • Strong active straining > 30–60 minutes with no puppy delivered
  • More than 4 hours between puppies while others remain inside
  • Green/black discharge before the first puppy is born (indicates placental separation before delivery)
  • Bitch appears exhausted, collapsed, or in severe pain

Stage 3

• Passage of placentas (one per puppy).
• Count placentas — there should be one per puppy. Retained placenta causes infection.
• The bitch will eat placentas (natural behavior — contains oxytocin and nutrients). Allowing 1–2 is fine; remove extras to prevent vomiting/diarrhea.

PART 3: IMMEDIATE POST-PARTURITION CARE OF THE BITCH

First 24 Hours After Whelping

1. Offer food and water — the bitch is exhausted and may be hypoglycemic. Offer warm, palatable food (broth, chicken and rice, puppy/lactation diet). Many bitches will not eat for the first few hours; this is acceptable.
2. Monitor for retained placentas — signs include continued straining, foul-smelling green/brown vaginal discharge (lochia), lethargy, fever. Normal lochia (post-whelping discharge) is dark green/black turning red-brown over 2–3 weeks, odourless.
3. Monitor for eclampsia (hypocalcemia) — most common 2–3 weeks post-whelping but can occur immediately:
   • Signs: muscle tremors, stiffness, panting, hyperthermia, seizures.
   • Emergency: IV calcium gluconate by a vet. This is life-threatening.
4. Temperature: Check rectal temperature once daily for the first week. Fever > 39.5°C (103°F) may indicate metritis (uterine infection) or mastitis.
5. Check mammary glands: Should be soft, warm, and productive. Hard, hot, painful, or reddened glands = mastitis. Requires veterinary treatment.
6. Uterine involution: Normal lochia for up to 3 weeks. Any foul smell or bright red hemorrhage requires veterinary assessment.
7. Nutrition for the lactating bitch:
   • Caloric requirement increases dramatically — up to 3–4× maintenance at peak lactation (weeks 3–4).
   • Feed a premium puppy/lactation diet ad libitum (free choice).
   • Multiple small meals throughout the day.
   • Water intake must be very high — offer clean water at all times.
   • Do NOT restrict food during lactation.

PART 4: NEONATAL PUPPY CARE — IMMEDIATELY AFTER BIRTH

At Birth — First Minutes

Signs of a Healthy Newborn

• Active, strong suckling reflex within minutes of birth
• Vocalizes (cries) when cold or hungry
• Pink mucous membranes
• Normal birth weight for the breed

Signs Requiring Immediate Attention

• Cleft palate (check roof of mouth)
• Gasping, persistent cyanosis
• Birth weight < 25% below litter average (fading puppy risk)
• No suckling reflex after 30 minutes

PART 5: COLOSTRUM FEEDING — THE MOST CRITICAL FIRST STEP

Why Colostrum is Essential

• 100% of passive immunity comes from colostrum (the first milk).
• Colostrum is produced in the first 24–72 hours after whelping.
• It is rich in: IgG, IgA, IgM, growth factors, leukocytes, lysozyme, lactoferrin, vitamins (especially A and E), and energy.

The 12-Hour Window (Critical)

• The puppy's gut epithelium has specialized cells capable of absorbing intact immunoglobulin molecules (macropinocytosis).
• This "gut closure" occurs at approximately 12–16 hours after birth.
• After gut closure, IgG molecules can no longer be absorbed intact — colostrum consumed after this point provides only local GI protection, not systemic immunity.
• Every puppy MUST receive colostrum within the first 12 hours of life — ideally within the first 2–4 hours.

Ensuring Adequate Colostrum Intake

1. Help each puppy find a nipple — especially the smaller/weaker ones.
2. The dam has more mammary glands available than most litter sizes — ensure all puppies rotate.
3. In large litters, rotate puppies to ensure each gets adequate access: remove those who have fed (place in warm box) and allow the smaller ones to nurse uncontested.
4. Check that each puppy is actively swallowing, not just mouthing the nipple.
5. A well-fed neonate has a round, full abdomen.

When Dam Has Insufficient or No Colostrum

• First choice: Source colostrum from another recently whelped bitch of the same or similar species.
• Second choice: Commercially available canine colostrum supplements (e.g., Breeder's Edge Okstre Canine Colostrum, Nurturall-C Colostrum) — these contain bovine colostrum with IgG and growth factors.
• Last resort: Puppy milk replacer (KMR, Esbilac) — provides nutrition but not passive immunity. These puppies will be immunologically naive and more susceptible to infection.

Colostrum Supplementation Dose (if tube/bottle feeding)

• 1–5 mL per puppy (depending on birth weight) every 2 hours for the first 12 hours.
• Do not overfeed — aspiration pneumonia is a major risk.

PART 6: ONGOING PUPPY CARE (First 2 Weeks)

Feeding Schedule

• Puppies nurse every 1–2 hours in the first week — continuous access to the dam is essential.
• If a puppy is not gaining weight, supplement with tube or bottle feeding every 2 hours:
  • Week 1: Approximately 13 mL/100g body weight/day
  • Week 2: Approximately 17 mL/100g body weight/day
  • Week 3: Approximately 20 mL/100g body weight/day

Weight Monitoring

• Weigh every puppy once or twice daily for the first 2 weeks.
• Puppies should not lose weight after the first 24 hours; small initial loss (up to 10%) is acceptable.
• Healthy weight gain: 5–10% of birth weight per day.
• Any puppy not gaining weight by day 2 must be supplemented.

Temperature Requirements

• Neonates cannot shudder/shiver to generate heat.
• Environmental temperature for puppies:
  • Week 1: 29–32°C (84–90°F)
  • Week 2: 26–29°C (79–84°F)
  • Week 3: 24°C (75°F)
• Use a thermometer in the box — not just a heat lamp.
• Provide a heat gradient so puppies can move away if too hot.

Stimulation for Urination and Defecation

• Neonates cannot urinate or defecate independently for the first 2–3 weeks.
• The dam stimulates elimination by licking the anogenital area.
• If hand-rearing, use a warm, damp cotton ball to gently stimulate the area after every feeding until the puppy eliminates.

Eyes and Ears

• Eyes open at 10–14 days.
• Ear canals open at 12–16 days.
• Before opening: keep away from bright lights. If eyes appear swollen or discharge accumulates before opening, bathe with saline and see a vet (neonatal ophthalmia).

Socialization Begins

• Begin gentle handling (Early Neurological Stimulation) from day 3–16.
• Keeps puppies accustomed to human touch.

Deworming

• Puppies are virtually always born with Toxocara canis larvae (transplacental and transmammary transmission).
• Begin deworming at 2 weeks of age, repeat at 4, 6, and 8 weeks.
• Commonly used: fenbendazole or pyrantel pamoate (safe in neonates at 2 weeks+).

Vaccination Schedule

• First vaccines: 6–8 weeks of age (distemper, parvovirus, adenovirus — DA2P core vaccines).
• Maternal antibody interference is reduced by this time.
