Large dog (rotweiler) is not well-exercised etc by owners and getting more fierce We are too afraid to go out into our back garden : aneighbour alerted us just inthe nick of time the other day and we returned home to find the dog pounding at our back door No doubt he would take a large chunk out of us if he could. We have thought about a fence but fear it would only make things worse as he would just go at it till it breaks .Anyway why should we have to pay for a fence ? Council not being helpful.
