A dog owner has been fined £450 for failing to clean up after his pet, while another was charged £130 for walking her collie in a dog free zone.
Both cases were brought before magistrates by Brighton & Hove City Council.
Anthony Gallagher of Windlesham Road, Brighton, was fined £100 and ordered to pay £350 costs after failing to clear up after his pet after it fouled in the street.
He was reported by a member of the public after the incident in Goldsmid Road.
Beverley Dunn of Brunswick Street East, Hove, was fined £80 and ordered to pay £50 costs after walking her pet in the "no dog" area of residential Brunswick Square Gardens.
Most dog owners are very responsible in respecting by-laws and the need to control and clean up after their pets in public places.
"So, it is disappointing when we find it necessary to expend scarce council resources on pursuing fines. We hope the results of these cases will encourage all dog owners and walkers to be more considerate.”
