Resumen:
A voluntary collaborative exercise aiming at the mitochondrial analysis of canine biological samples was
carried out in 20062008 by the Non-Human Forensic GeneticsCommission of the Spanish and Portuguese
WorkingGroup(GEP)oftheInternationalSocietyforForensicGenetics(ISFG).Theparticipatinglaboratories
were askedto sequencetwodogsamples (onebloodstainandonehairsample) for themitochondrial D-loop
regioncomprised between positions 15,372 and 16,083 usingsuggested primers and PCR conditions, andto
comparetheirresultsagainstareferencesequence.Twenty-oneparticipatinglaboratoriesreportedatotalof
67.5% concordant results, 15% non-concordant results, and 17.5% no results. The hair sample analysis
presented more difficulty to the participants than the bloodstain analysis, with a high percentage (29%)
failingto obtain a result.The highlevel of participationshowedthe interest of thecommunity in theanalysis
of dog forensic samples but the results reveal that crucial methodological issues need to be addressed and
further training is required in order to respond proficiently to the demands of forensic casework.
