The Dogs (Fouling of Land) Act 1996 took effect from Friday (July 23) and will allow the council's dog wardens to crackdown on the problem of dog mess.
Under the new act North Somerset Council has designated all open land to which the public has access as areas where owners must clear up after their dogs.
Some areas are exempt from the new law including woodlands, marshland and heath, agricultural land, rural common land, and roads with a speed limit of more than 40mph and land running alongside them.
At first, dog wardens will be targeting known problems areas in North
Somerset using both marked and unmarked vehicles, in uniform and plain
clothes, and at times popular with dog walkers.
'There are many responsible dog owners in North Somerset who clean up after their pets. This new legislation is needed to help us crackdown on the selfish minority who continue to let their dogs spoil our open spaces for other people,' said Peter Bryant, vice-chairman of North Somerset Council's environmental services committee.
