When do dogs start producing colostrum? - in detail

Dogs begin producing colostrum, also known as first milk or beestings, in the later stages of pregnancy. This process is crucial for the health and survival of newborn puppies. Colostrum is rich in antibodies, proteins, and other vital nutrients that provide passive immunity to the pups, protecting them from diseases during their early life.

The exact timing of colostrum production can vary among individual dogs, but it generally starts around day 40-45 of gestation, which is approximately two weeks before whelping. During this period, the mammary glands in the bitch's body begin to swell and prepare for lactation. The colostrum produced during these final days of pregnancy is particularly potent and contains high concentrations of immunoglobulins, which are essential for the puppies' immune system development.

To ensure that newborn puppies receive adequate amounts of colostrum, it is important to allow them to nurse within the first 12-24 hours after birth. This initial nursing session activates the suckling reflex in the pups and stimulates further production and release of colostrum from the bitch's mammary glands. Puppies should continue to nurse frequently during their first few days of life to maximize their intake of this vital substance.

In summary, dogs start producing colostrum around day 40-45 of gestation, with peak production occurring just before whelping. Ensuring that newborn puppies have access to colostrum within the first 24 hours after birth is crucial for their health and survival.
