Hi thanks for your question, I just need somemore information.
When was she bred
When did you notice her nipples drop
are they producing milk(does small amount of milk appear when squeezed
i worked out from when they mated that sixty three days will have passed on the 19 th of october.
her nipples have dropped all of a sudden today they are not normally as big and as low as they are now
there is not any milk as yet
ok,
You still have some time as gestation is normally 58-62 days.
The easiest way for most owners to tell when labor is close is to monitor her temperature
A dogs normal temperature is 101.5-103
When her temp drops below 100 she will have the pups within 24 hours.
If you have not already done so you should start feeding puppy food and continue until the puppies are weaned.
You also did not mention weither she was an american or english. If she is an English please watch her very closely when labor starts as almost 90% of this breed require a c-section.
