Puppies two to four weeks of age feed well every 6-8 hours. Weaning, as described below, should begin at three to four weeks of age. After birth and for the first few days, puppies should generally be fed every two hours, even at night. After a couple of weeks, the interval between each feeding will naturally increase and puppies will be able to go four to six full hours between each breastfeeding session.
Newborn puppies need to breastfeed approximately every two hours. Their mother stays with them most of the time, allowing them to eat when they need it. As they mature, the time between feedings increases, until around four to five weeks the pups are old enough to begin weaning and transition to solid foods. Puppies under two weeks of age should be fed every 3-4 hours.
