This morning our fire alarm went off because of the steam from the shower. I was standing right underneath of it. I don't think Quinn jumped, and it was LOUD. Or maybe I jumped so hard that I couldn't feel him jump. The first time I felt him actually startle at a noise was when he was aout 15 weeks... I know that seems young but my dog gave out one of his real low pitch, loud ass barks right at my belly. It felt like my stomach came alive! Maybe he's just use to sudden noises because of the dogs and hitting snooze on my alarm clock every ten minutes.
