Stage 2
- Depends upon the number of foetuses, but usually lasts ~6 hours.
- Straining indicates the onset of the second stage.
- Bitch remains in her bed in sternal recumbency
- 'Water bag' of the first foetus appears at the vulva, and attains the size of a golf ball.
- Bitch licks the vulva vigorously and usually ruptures the 'water bag'.
- Delivery of the head requires the greates effort, once this is bord the rest of the foetus follows easily.
- Expulsion of the first foetus may take up to 1 hour.
- Umbillical cord is intact at birth, the mother will soon bite it away.
- Bitch rests for a time after the birth of the first puppy.
- Lies licking the puppy, which soon begins to suckle.
- Pays frequent attention to the vulva and licks any discharge.
- Foetal membranes generally voided in 10-15 minutes and eaten by the bitch.
- Straining recommences after a delay of 30 minutes - 2 hours.
- Effort and time required for subsequent deliveries is usually less than the first.
- May rest in between subsequent deliveries, but may not. The period of rest is also very variable.
- Puppies tend to be expelled from alternate horns (unlike the sow).
- Expulsion of foetal membranes is also irregular, they may come out individually, or the next puppy may be born with the membranes of its predeccessor around its neck.
Stage 3
- Membranes of the last foetus are expelled with it or shortly afterwards.
- Discharge is dark green in colour.
- Due to breakdown of the marginal haematoma, blood pigment biliverdin escapes.
