Lucy has peed in our bed like four times now and last night was the first night I caught her. She was scratching and circling like she was about to find a comfy spot to lay down and then all of the sudden she squatted and peed. I spanked her all the way out the back door. She sat out in the backyard for like 30 minutes until I told her she could come back in. The thing that gets me is she does not have accidents in the house anymore and knows to go outside, these are the only accidents (going in our bed) she has had in probably a month. Any suggestions?
