If you have a dog in the house, make sure you replace your smoke detector battery. My smoke detector started chirping yesterday, warning me that the battery was low. When I get home from work, I see Georgia slinking around the house and then she went into the backyard and didn’t want to come in. Initially, I didn’t get it, but finally figured out that she was freaked out by that chirping, she was whining and wimpering up a storm. I immediately changed the battery. I almost didn’t get her to come in so we could go for a walk. But all was resolved, after our walk I don’t think she even remembered that she was upset.
