Its a good idea and I have explained my feelings before on here.

All dogs should be chipped and have DNA taken.
Any dog mess on the street should be tested and the owners fined.
Any dog bites could have the dog saliva tested and the dogs owners fined and the dog put to sleep

Any un chipped dogs detected after a certain date should be put to sleep.

It might sound a little harsh but I am interested in the well being of humans over dogs.

All chipping, testing and possible insuring should of course be at the dog owners expense.
