Have you heard of dog DNA testing? It sounds so CSI-ey for me. Hee hee. It is my first time to hear about it and it made me curious to know what it is for. But before I hit Google search, my hunch is that this testing helps in developing better dog breeds, among the many other purposes. Especially so that dogs act as enforcer of peace and security anywhere from malls to airports. Aren’t they the coolest?
