It is an offence if the owner of a dog allows their animal to foul in a public place without clearing it up.
If an authorised officer witnesses you not cleaning up after your dog, you may be given a fixed penalty. If you refuse to pay the fixed penalty you may be taken to court and be fined up to £1000 plus court costs.
If you witness someone letting their dog foul in a public place without cleaning it up afterwards, you should report this to West Northants Council using the link below. Include the name and address of the person in charge of the dog (if known), a description of the dog, plus details of the date, time and place of the offence.
Towcester Town Council provides over 70 dog waste bins on its open areas in the town and its contractor empties them frequently.
