There will be restrictions on dogs for portions of the Westward Ho! beach and the promenade from May 1.
Torridge District Council said the restrictions will run until 30 September.
It said dogs would be allowed at the northern end of the beach between Sandymere Bridge and the Taw/Torridge estuary and at the head of the promenade.
The council said fixed penalties of £100 would be issued if landlords did not comply.
Mike Day, Northam Burrows Lead Ranger, said the restrictions helped provide dog free and dog friendly areas on the beach.
He said: “Not only is this an important part of the Blue Flag standard, it also means that dog lovers and those who are not so fond of man’s best friend can enjoy this wonderful place at the same time.
“We recognize what an incredible place Westward Ho! is, and we want as many people as possible to enjoy it.”
Signs will be posted to ensure dog walkers are aware of the restrictions.
