Did you think it was just humans that had to worry about DNA evidence? Now thanks to one start-up from across the pond, your dogs might be getting nervous too.

BioPet, based in Knoxville, Tennessee, is marketing a range of pet-related products which use DNA technology, led by their PooPrints system. The system collects saliva swabs from every dog in a participating area and registers the DNA in a central database. Sound familiar?

When residents find dog droppings, they mail them to BioPet. Technicians then match the DNA to reveal the offending owner. BioPet make $30 for every pet enrolled and $50 for every test.

Quite how this system will be policed by the apartment owners and town administrators that it’s being aimed at is an interesting question!

Other products in the BioPet line-up include a proof of parentage test; a genetic ID kit, which lets owners register a pet DNA sample for proof of ownership; and a breed identification test that reveals every single breed in your mutt’s family tree.
