I'm glad this has come up and have had probs. with neighbors dog barking, long story short, my missus complained again to the local authority, jeez 4 trucks 4 motorbikes all turned up (elections are coming up) , they have TEN dogs, well they also own the house next door, And apparently you are allowed 5 dogs per house.
My point is that; it's a crazy law, and should go on how big your land is. whatever size a dog, it still has a bark.
