When I was a child, the school nurse had a large dog that she brought to work. It wasn't approved, but even if it was, I don't think it's remotely appropriate to have a pet in a nurse's office with sick children. There were complaints, of course, but this woman was so SS that she would turn up late to work so no other staff would see her arrive, and bring the dog in anyway. Clearly they had a problem with hiring someone new, although I don't know why.
Us students were aware of the problem. Those of us who were unfortunate enough to have dog allergies (more common than you'd think, it turns out) would have trouble approaching the nurse for anything. She always dismissed any requests to perhaps not be standing next to a large, fluffy, allergy-causing animal as, "oh, he's not bothering anyone!" despite being told that he very much was just by being present. One girl in my year couldn't walk directly past this woman's office and had to take a detour just because the presence of dog hair alone was enough to set her off, so strong were her allergies.
Usually we'd just convince a friend to feign illness and transfer the bandaids, aspirin, etc. to us afterwards. This involved fake tablet-swallowing in front of this nurse, and an almost black market-level of trade of medical goods, not to mention very poor first aid done by children on other children, attempting to copy what they'd seen the nurse do. Whenever I see prison films where they trade with cigarettes, I know just what it's like.
This SS woman put her dog in front of the very children she was hired to care for. And caused a lot of unnecessary unsafe and medically-unsound activity in the school.
