Dog mess is a nuisance and it's associated with various diseases including 'toxocare canis'. Dog owners should clean up after their dog in public places.
If you see fouling in these areas, report it to your local council. If possible, give details such as the name and address of the offender or, if not, a description of the owner and the dog.
Penalties
People who do not clean up after their dog can be given a £50 on-the-spot fine. If they refuse to pay the fine, they can be prosecuted and may face a court appearance with a maximum penalty of £1,000. Registered blind dog owners are exempt from penalties.
