This study was performed to investigate the possibility of superfecundation by surgical intrauterine artificial insemination in dogs of confirmed genetic pedigree. Artificial insemination was performed on 3 days after ovulation with $1.3{\times}$ $10^8$ spermatozoa. Five puppies were delivered on 60 days after insemination. The ratio of the number of newborns to the number of corpora lutea was 83.3% (5/6). Parentage analysis with 10 canine-specific microstatellite markers demonstrated that one puppy was genetically relative to the sire-A family and four puppies were genetically relative to the sire-B. The present study demonstrated that two kinds of puppies with different genetic pedigree can be produced by surgical uterine insemination of semen of individual dog into each uterine horn of a bitch.

Microsatellite allele analysis has been used for individual identification and paternity test. In the present study, the biological father of three puppies was determined by using microsatellite allele amplification analysis. The mother bitch of the litter was a Poongsan dog. The three stud dogs that could have inseminated the bitch, by being in the same residence, were a white Poosan dog, a mixed breed, and a white Jindo dog. DNA was obtained from all the relevant dogs by buccal swabbing. Four loci of tetranucleotide repeat microsatellite were PCR-amplified, and analyzed by polyacrylamide gel electrophoresis and silver staining. The results of genotyping unambigously assigned the Poongsan dog as the biological father. There was no evidence of superfecundation. Therefore, the present study demonstrated the usefulness of microsatellite allele analysis as a simple, efficient method of paternity test in dogs.
