Dog owners who fail to clean up after their pets could be shamed with wanted-style 'pugshots'.
Since January Barking and Dagenham council in east London has been using DNA techniques to identify owners who fail to clean up dog mess.
The DNA samples could also be used to create a computer generated image of the animal.
Key information taken from the samples will include gender, coat texture, length and colour and nose and eye colour.
Details of face type, whether the animal has a flat face or a projecting nose, will also be revealed.
