Not everyone likes dogs or wants to deal with dogs on a day out at the beach, especially when they have small children with them.
Other than a fear of dogs there is also the possibility of an overly excited dog running or jumping on kids or peeing on sandcastles, which do not make for very happy children.
Moreover, beach runners may prefer a beach without dogs as dogs with a high prey/chase drive may chase/attack a runner.
But many people also enjoy dogs on beaches. There is very little more beautiful than an animal thoroughly enjoying itself in nature and being free.
And this is true also for birds and other wild animals!
Zoning will help people, dogs and our shorebirds live their best lives.
