Dog is very gentle ( as good as Lassie himself)but 5 stone, but I have been so worried about it all I have currently sent him away. DD is 1 and crawling /cruising fast. Its just that I have awful visions of what could happen in worst case scenario. (In fact my dog bit me as a child and got put to sleep) Do I need to supervise constantly / not let her out of vision? Do I need to lock dog in separate room? What do other, but non anxious people do?, thank you.
