The use of multiple sires is allowed by the American Kennel Club as long as pups are DNA
tested to confirm parentage. It is a great way to make use of the more limited reproductive life
of a female...almost like having two litters in one. There will be more variety in the combinations
of genes. And it is also interesting to watch pup's temperament develop, since the pups all
have the exact same environmental influences, we expect any differences to be due to heredity
(allowing for the differences among different pups within the same litter, of course). Wren was
bred to Quincy and Ray at the same time by artificial insemination, since our first attempt at a
multi-sire litter resulted in only pups from the first male to naturally breed.
