My dog's a she and she is trained to go on newspaper that's in a downstairs washroom, to which she has free access, so this incident has caught me by surprise. She is not allowed on the bed but for the past couple of days she has been jumping up on both my bed and my mom's bed, this is the only odd behavior I've noticed in her, other than that she acts just like she normally would. I might add that on the same day she pooped on the bed I accidently locked her in my brother's bedroom, she was in there probably close to an hour before I noticed some faint wimpering. Maybe this was the cause? She's not used to being isolated from everyone else.
