unless a notice containing a warning that a guard dog is present is clearly exhibited at each entrance to the premises '. Dog Control Orders (replacing dog byelaws) From 6 April 2006 local authorities no longer have to rely on the creaky old byelaw system to control dogs on public land. The problem with this old system was that making new byelaws used to take years, if not decades, and so it was very easy for them to get out of date, if, for example, the council opened a new park or closed part of an old one. Section 6 of the Clean Neighbourhoods and Environment Act 2005 provided a new way of controlling dogs, allowing local authorities and parish councils to introduce controls on dogs in certain areas without confirmation by the Secretary of State. Councils will still be able to make new byelaws to control dogs if they wish to do so, but only in relation to offences that cannot be prescribed in a Dog Control Order. Existing byelaws remain in force indefinitely, and can continue to be enforced as normal. See DEFRA Dog Fouling page for more details. The new law repeals similar powers under The Dogs (Fouling of Land) Act 1996 , and under Sections 55 -- 67 of the Clean Neighbourhoods and Environment Act , Dog Control Orders replaced existing local authority and parish council powers to designate land for dog control. Both types of authority can control dogs by way of Dog Control Orders
