Many thanks for your swift response and whilst you are far more qualified than I am in these matters does the fact that the dog has already 'had a go at me' (6ft ish) and that I have had 30years of experience with dogs - not change the situation at all - considering the ages of my young children? It seems 'odd' that if I had chickens/lambs etc then I believe the situation would alter drastically. Please understand that I am not trying to undermine your answer at all but it doesnt seem right that visious dogs are allowed on my land and are allowed to terrorise me/my children.
OK. Many thanks for clarifying these points. I do believe that had I not been so close to a door then I could indeed have been injured but I'm not planning on hanging about deliberately to prove that point. I suspect that CCTV evidence may help in future to ensure that nobody has to act in any way other than securing the property to ensure that it can't access it.
Many thanks and best regards,
Great, Thanks again. Enjoy what is left of the weekend :-)
