Heat Lamp For Newborn Puppies. You want the heat lamp set up so that it keeps the puppies warm, but you don't want the entire whelping box directly heated, otherwise you risk overheating the puppies. The lamp should be placed high enough above the box to prevent any risk of burning the mother or her pups, and there should also be a cooler corner that the pups can crawl to if they get too warm.
The larger the litter the lower the environmental temperature needs to be, since the puppies will huddle together and keep each other warm. Artificial heat should always be closely supervised. If you have to use a lamp, be sure to check the puppies regularly for flaky or red skin.
It mounts to the side of the whelping box.
Heating the area over the whelping box with the aid of a heat lamp is usually all that is necessary. Heating for newborn and neonate puppies is crucial, as body temperature is a key factor for survival. Hang the heat lamp over a corner so there's at least a small corner or a side of the box the puppies can move to if they begin to feel too hot. Heat is emitted by the lamp and directed toward the cradle.
