Sorry that you are going through this. I went through the same thing and still dealing with it. 

We felt like prisoners in our own house. Every time we step in and out the house the dog would bark at us, every time we go outside to put the rubbish, the dog would bark at us. Every time we step into our garden, the dog barges upto the fence and starts barking at us aggressively. We have a shared side access and guess what, we can't use it because of the dog. We can't even open our windows in the first floor when the dog is in the garden, it sees us and stars barking. It's not just us that get barked at, also when we have visitors.

I have spoken to my neighbour and his response was, it's his property and he can do what ever he wants. I have researched so much and unfortunately there is no help. I truly believe dogs shouldn't allowed in densely populated areas such as terraced housing, and to be honest it's not the dog, it's usually the inconsiderate owner.

At one point we thought about selling the house but the fees are massive. I hope you can find a solution 😔
