Newborn Puppies & Weight Gain


A healthy newborn may lose weight in the first few days of life but should start to gain weight by the time she is forty-eight hours old. In fact, she should double her birth weight in eight to ten days. A good indicator of a pup's potential to put on healthy weight is to see if the mother is gaining weight, as this is a sign that she has the nutritional support available to pass on to her litter.

A puppy that loses 10 percent or more of her birth weight in the first two days of life and does not start gaining by three days probably will not survive unless she is hand-fed. Learning how to properly hand-feed your puppies is imperative, as mistakes in feeding can result in trouble. A puppy who at birth weighs about 25 percent less than her litter mates should be placed in an incubator and hand-fed. Many underweight puppies can be saved if quick action is taken and their weakness is not complicated by disease or hereditary defects.
