Mr. John Joe Fitzgerald:

The biggest problem we see with microchipping and dog licences is that when the farmer gets to the field there is no trace of the dog.

That is the biggest problem I hear from every farmer in the country. DNA sampling is a very easy system. It is either a swab, a blood sample or a skin nick. If it is a viable sample we put it back into the database. When a kill happens after that and if the farmer gets to the field the dog is gone he can test the saliva on the tears and cuts on the dead or torn animal and go back to the database and find the dog's owner.
