Kelly called me last night and told me she heard this on the radio and thought you all might be interested..she is swamped with work all the time so doesnt' have time to post..so this is all second hand and i hope i tell it right..the question was why should you collect your dog's dna..the answer was for theft or indentifcation..and the second question was how do i do that..and that was easy..take a swap swap the cheek put in a baggie seal and freeze. Is good for years.
