Molly howled for the first time today. My husband was in the bathroom getting ready for work (she hates it when anyone is in there because she likes to be able to see everything.) She was watching the bathroom door from the sofa and he turned on the water, she didn't know what that sound was and let out a big howl. I was really surprised as she had never really even barked before, but I wasn't nearly as surprised as she was because she looked around, jumped off the sofa, and ran around, I assume, looking for whoever had just made that loud noise. I am sure that she will get over her surprise and go on to many many more days of howling.
