There can be lots of reasons for fecal incontinence (during sleep or otherwise). At this age, especially in a large dog (that tend to age more quickly than smaller dogs) I would start investigating the cause and treatment with a visit to your vet. Bring a stool sample to help rule out parasites.
If you still don’t get an answer then I would consult a homeopathic vet.
S/he will treat this symptom as just one of the many low-grade energetic issues which your older dog may be experiencing (common but not normal symptoms [url]https://www.homevet.com/common.html)[/url]. Once the internal dynamic imbalance is corrected, this symptom should resolve.
