However, it's important to note that every dog is different, and some may begin lactating earlier or later.
Here's why lactation starts before birth:
* Preparation: The body needs to be ready to nourish the puppies immediately after birth.
* Hormonal changes: As the dog's body prepares for birth, hormones like prolactin increase, triggering milk production.
If you notice your dog lactating, it's a good sign that she is nearing her due date.
