Souraya, no other dogs have come into our home!! Killi is so good natured, I think he will be fine (I hope, you never know for sure). Shiloh will be fine unless he growls at her, she will not tolerate any lip. (UH, OH) Yesterday, when he came too close to her mouth to sniff, she raised her lip and unlike when he did it to Killian, he had to be told to leave it, with Shiloh, as soon as she raised her lip, he backed off. Maybe he already knows she is gonna be boss. (Well, I'm going to be boss and she will be my helper LOL). I am so paranoid. GSDs are large with big teeth, don't want anyone hurt!!
