This Visit Arran Leaflet is based on the Scottish Outdoor Access Code
Keep your dog under close control when you are in areas where ground-nesting birds are breeding or rearing their young. This is especially important between the months of April and July (breeding season), and includes areas such as moorland, grassland, forests and the seashore.
There is no specific definition of what 'under close control' means. However, it is expected that, if your dog is under close control, he will be able to respond to and obey your commands immediately. If you are not confident that your dog will, for example, sit or lie down on command, you should keep your dog on a short lead. A 'short lead', for the Scottish Outdoor Access Code, is defined as 2m or less.
