Compulsory DNA 'poo-profiling'
There's no doubt about it, dog mess is an everyday feature of urban life, with a small minority of dog owners making a health hazard of our streets, gutters and children's playgrounds.
But how do you solve a problem like this? Over in the USA, one company is pioneering a hi-tech but politically charged solution: compulsory DNA poo-profiling.
Many upmarket apartment complexes in America allow their tenants to own dogs and to walk them in their neatly landscaped grounds. But a minority of irresponsible residents fail to scoop up their dog's poop.
PooPrints analyses samples of poo sent in by the managers of these apartment complexes and compares them to the genetic profiles of that community's canine residents. If a match is found, PooPrints tells the property's management, who may then fine or even evict the owner.
How does PooPrints get hold of the DNA of every dog in a complex? Well, dog-owning residents are obliged to provide their pet's DNA (and must pay to cover the cost of this) under the terms of their tenancy. The complexes argue that because they are private developments, they can make their own rules - if tenants disagree with the policy, they can simply live elsewhere.
And if you're thinking 'only in America', think again: local authorities in Italy, Germany and Israel have trialled similar schemes in recent years - and some councils in the UK are keen to follow their lead.
But would such a scheme be workable on a larger scale across a British district, city or county, where thousands of dogs may live? Would it be voluntary or mandatory - and if it's the latter, how would this be enforced? How would you appeal against fines? And what would you do if you didn't agree with the imposition of dog DNA testing where you live?
Would you be happy to have your dog's DNA kept on a database in order to help keep our streets, parks and countryside clean? Or do you think this would be an Orwellian step too far?
