The latest trend I am seeing involves DNA testing for dogs. Some offer home kits so the curious can see what their dog really is. Some suggest that knowing the prominent breed in a pet will help preempt behavior issues with proactive training techniques. Others suggest it can be a panacea in some legal matters. I say before blithely jumping in, selling home kits, creating databases, inviting DNA booths to dog walk festivals, and participating in a collective knee jerk response of blind acceptance - we think about the intended results, the unintended consequences, the ethics involved and what the criteria for best practices in the usage of this information should be.
