Well they are dogs. I doubt they really think about such things and when they mate she is pretty much a single mom and dad is the sperm donor. Often the male does not live anywhere near the female and sometimes the sperm is inserted by a vet.
The sperm are always younger than the eggs. The female is born with all the eggs she will ever have. The male is constantly creating new sperm so if you look at it that way......
