For newborn Labradors, only mother’s milk should be given until two months. If not available, you can consider buying a good baby dog milk for them. Newborn pups can be fed this milk every 2-3 hours. Puppy Labradors above two months would need 50-50 grams of food four times a day. Grown-up labradors can be given 400 grams in a whole day divided into two meals. As senior labs would be mostly inactive, they can be given 300-350 grams of food per day divided into two meals.
