How to make sure newborn puppies receive enough nutrition
Opt for the mother's milk whenever possible.
A mother's milk has the nutrients necessary for puppies to thrive. A mother will also be able to feed her puppies enough milk without a lot of intervention.
When possible, a mother's milk is always the best option. You should only attempt to bottle or syringe feed if the puppies are orphaned or if the mother rejects the litter.
