Answer
You should have learned about taking care of newborn puppies. They cannot regulate their body temperatures and that is what killed them. Your lack of knowledge.

You also should have called a vet immediately.

It is Boxer owners like you that should not allow their dogs to breed.

Sorry for being blunt-- but that angers me.
