Milk production in dogs is started during advance stages of the pregnancy. Usually, it starts during 8th week of pregnancy. But in some dogs, it starts 2-3 days before delivery. In some dogs, milk production is started on the day of delivery and in some dogs, after the delivery. So, you can not predict exact delivery date in dogs by noticing milk production. You should watch for signs of labor which
start 8-48 hours before true labor. These signs are decrease in rectal temperature below 100, agitation, no eating, restlessness and pacing.
Milk let down is an unreliable way to measure how long it is before she whelps. There are a few signs of pregnancy in the dog that you may notice. Pregnancy lasts approximately 63 days. The earliest signs include decreased appetite, a decrease in activity may be noticed, and nipple enlargement. As pregnancy progresses, you may notice an increase in appetite and weight gain. In late term pregnancy the abdomen will increase in size, you may even see or feel the puppies move about, and milk production may begin. Imminent signs of delivery include change in behaviour, restlessness and nesting behaviour. Breeders will measure the mother's rectal temperature twice to three times daily close to the delivery date. The mother's temperature will drop 1-2 degrees Celsius 24 hours before whelping.
