This hatred of dogs (bans everywhere) is unacceptable when there are much more uncivilized people. Further along is a dog-friendly beach, but it's much more inconvenient if you have children in addition to a dog...
I don't understand why the locals aren't saying anything.
It's better to go elsewhere at this point (dog-friendly Lake Levico, for example), worse for them, they'll lose a slice of tourism.
