Pregnancy
Pregnancy in a dog lasts for an average of 63 days. Signs of pregnancy
include enlargement of the abdomen and mammary glands (breasts).
Ultrasound can be used to detect pregnancy from 28 days and Xray
from 42 days. Most dogs will produce milk in the last week of
pregnancy and start nesting behavior (digging holes and ripping
paper etc.) several days before giving birth. In most bitches
their body temperature will also drop to 37?C or below in the
48 hours before birth. False pregnancy (pseudopregnancy) occurs in small number of bitches
where they show many signs of being pregnant without having conceived. Related sites |
