Here's a breakdown of the process:
* Pregnancy: During pregnancy, the dog's mammary glands enlarge and prepare for milk production.
* Labor: As labor progresses, hormones trigger the production of colostrum, a thick, yellowish fluid that is rich in antibodies and nutrients essential for the puppies' immune system.
* Postpartum: After birth, the production of milk increases significantly, and the colostrum gradually transitions to regular milk.
It's important to note that the amount and consistency of milk production can vary between dogs and depend on factors such as breed, age, and health. If you have concerns about your dog's milk production, it's best to consult with a veterinarian.
