Molly is 18 weeks old, has been with us for about 7 weeks now and just this week it seems like she has given up on using her pee pad. She was doing so well and now she will pee everywhere in the house except the pad. I fuss at her when she does this and she looks at me like she knows that she did wrong. I have all the pads in the same place, change them out each day and even added more around the house. They don't even seem to faze her! She is free to roam with me in the house all day and sleeps in bed with us at night. She has never had an accident at night and also seems to be stubborn early in the am when I put her with me in the bathroom. She is being a typical female according to my husband

. Any suggestions???
