Hello! To give some context, I am a teenage year old girl and my neighbors both work night shifts sometimes during the week, and I sleep in their house overnight to look after their three children while they are away. Usually when I get there the children are in bed by the dog is always up and around; he is a gorgeous Alsatian cross (but I'm not sure what he's crossed with) and for some level of anonymity his name will remain "dog" . This dog was a stray on the streets of Italy that they took in to live with them. Not long after they took in the already anxious dog, they were the victim of two break-in robberies, making the dog even more fearful of people and especially men. This made them move back to England and they took the dog with them. The family are the most lovely people you will ever meet, and they treat him very well, so it is nothing that they are doing to cause this; he is very affectionate towards his family. When I first came to the house, the dog didn't make aggressive gestures as such, but avoided me entirely. Whenever I went to stroke him, he growled and showed his teeth which was a clear sign for me to back off, and I did. After being there for a few weeks, with treats and a gentle tone of voice, he will now come over and let me gently stroke his side, but looks incredibly uneasy and I prefer to leave him alone. His ears are always back when I am there, and as far as I am aware he has bitten three other house guests. Now, I don't need this dog's total love and affection as I completely get that he has had a traumatic start to life and you can't expect him to trust everyone! However I do feel really bad that for up to three nights every week, this dog is really stressed, scared and uneasy by my presence. I don't need cuddles from him or anything like that, but is there anything I can do behavior-wise or other to make the dog feel more at ease when I am around? Just so he is less nervous and can relax? I just hate the thought of him being worried by the fact that I am in his house.
