crazy??

My bf and I recently adopted our jack russel, penny. Penny is three and generally an okay dog. She is house trained and is kind to other animals and people. However, she is obsessed with the noises in the walls. She will cry until she gets into the closet where the wall is located. Once inside, she will stand and stare for several mins. I don't think there is something in the walls, any thoughts??
