Thank you for the advice I will call them tomorrow, I have just had a look at their site and they are exactly what I am looking for. The dog does sleep outside and because of her behaviour she comes in once the boys go bed, we also have gates into the playroom and bedrooms so there is no way she can go into their zones. I should clarify that my 5 year does need to act better around her, he is not mean but he does sometimes knock on the glass (we stop him) if she is outside and it annoys her she will hurl her body towards the glass, especially if she is eating. She will go for him if he tries to pat her, I tell him not to pat her. I never have the kids around outside if she is eating. We really don’t want to loose her but my children’s safety is obviously more important. She has been to puppy training. We live in the North Shore, we normally go to Hornsby vet.
