How to deal with newborn puppy nipple guarding
Weigh your puppies daily.
If you have a large litter of puppies, you should weigh each puppy daily. This will help you track their weight gain and make sure that each pup is getting its dietary needs met.
This will also help you highlight which puppies are nipple guarding and which puppies are malnourished. For the best results, use an electronic scale designed for weighing small animals.
