Question

why do dogs produce several puppies whereas human beings usually produce only one at a time?

Answer 1

Dog releases many eggs at a time and they are fertilized by sperms which produces multiple puppies. Also Survival rate of puppies are very low, so to maintain the survival of species they produce many puppies at a time. Whereas in case of human only one ovum is fertilized by sperm which results in one baby. Sometimes human also can give birth to more than one baby.

Answer 2

dogs produce more than one egg at a time Hence more puppies are born to them at the same time where as humans usually produce one egg at a time and produce only one child at a time
