Although canine models of various cancers garner increasing interest as in vitro systems suitable for studies of basic biology and drug development, the fact that breed specificity is observed for many types of cancer has excited geneticists who are anxious to localize susceptibility genes that have proved intractable in human families and populations.

Purebred dogs are the only system for undertaking this study for a large number of reasons, including low within - breed genetic diversity, high between - breed morphological diversity, and similarity to humans.
