Abstract
Canine microsatellites, comprising one to four base pair repeated sequences, were identified as part of a project to generate a genetic linkage map of the dog. They have been used to assign parentage in a range of doubtful paternity cases, for example, all the pups in a litter from a bitch mated on different days to two different stud dogs were identified by DNA analysis to come from one dog only. DNA typing in another case was able to exclude a male dog as the father of a litter. DNA analysis can be of relevance by allowing pedigree dogs, which would have previously been excluded on the basis of unknown paternity, to be registered with the appropriate kennel club.
