A good point by tatty-ead - I should have elaborated rather than simply answer the question as asked.
In what context was the question asked, Kathy? Did the person asking want to know whether a dog was actually
capable of mating with his daughter (yes), or whether a father/daughter mating is considered normal practice (in general, no).
If you could explain what the person who asked you was getting at, I'll be able to help better.
