It doesn't really sound like she would be suitable for kennels then,some dogs are and some dogs aren't suited,especially if she is a rescue dog,it could make her feel like your abondoning her. You sais she does't like other dogs,the kennel will have lots and also lot's of strange people so putting her in a kennel would probably be very distressing and scary for her. Why not try a better option of leaving her at home and either have someone you know come to feed her,walk her etc,there are lots of pet sitters out there or could someone you know not have her in their house whilst your away?
