The research project we participated in, for the past several years and eventually published with the UF team. shows that the seven dogs trained and tested, were initially imprinted on one species and once their proficiency levels reached the high 90, we introduced them to several other species and there was very little difference. So the answer is, if properly trained and imprinted a termite detection dog should be able to locate all species. Check out the results of our research(':DOGTONGUE:')
