Here's a funny story;
My mom told me one day that Karen (my dog) was acting strange at night, she was barking and barking. One day, when I went to clean the clothes on my washing machine, Karen tried to attack me, I thought Karen had some disease, my mom thought someone had broken in or that she was protecting us from something, and my dad thought she was keeping something from us that she didn't want us to take away.
When my dad came back from work one day she checked Karen, he raised his voice at Karen and she calmed down and smiled, then my dad figured out why she was acting so weird, she WAS keeping something away from us to keep us safe, the funny thing is that it was...
A washing product.
Yeah, she was protecting us from something she thought was bad, but it was just for washing clothes, she really got us worried, and now the dog is fine, she got happier and happier by the day (when we took the "Dangerous Object" away) and she still loves us even tho he doesn't get feed for about 3 hours because she woke up when we were still asleep.
