Since dogs are polygamous, females will mate with any available male dog while in heat. As a result, puppies from the same litter may actually have different fathers. As you might expect, the genetic variation among puppies with different fathers is greater than that of those who share the same father.
Can a female get pregnant by multiple males?
It is possible for twins to have different fathers in a phenomenon called heteropaternal superfecundation, which occurs when two of a woman’s eggs are fertilized by sperm from two different men. Ordinarily, a woman becomes pregnant because one of her eggs has been fertilized by sperm.
