| Are these fairly soft stools? If so, she could have a virus or something. Might check with the vet. There are several things that can cause soft stools and more urgent bowel movements. That would not suggest she has decided she is too big of a girl to stay in the crate as sometimes happens.
You could also try putting the divider back in. If it works, it would be an easy fix, but I don't expect it to.
Since she is 6 months old, you could cut back to one meal in the morning. |
