Dog walking in Norfolk- is it allowed ?

[Birdies]

Hi can anyone tell me if there are any places near Sherringham or Cromer area where dogsis allowed and we can see birdlife. Everywhere seems to be owned by one wildlife organisation or another and dogs are not welcome. We will be visiting for a week in April and would like to do some bird watchiog while on holiday , but will have the dog with us.I would appriciate any local knowledge of dog friendly walks. He will be kept under controll and on a lead as we do understand the problems dogs can cause wildlife.

Thanks
