some of these comments are a laugh!! i used to have a half bred ns dog here a real good worker and great with kids he d play all day with them but he didnt like adults male or female, he was a proper one man dog he was great with me but hated anybody else so we took precortions so people didnt get biten, out diggin he had the odd nip of anybody in his way but we coped , a lot of people would have shot him but you have to tune into the dog and get his respect then you have a chance of doing something with him
