I am sorry to hear about your problems with Marilyn. If she is still eating/drinking normally without any vomit/diarrhea/cough/lethargy/weakness then you could try a few different products to help ease any anxiety. There is a pheremone product called Adaptil that is available as a collar or a diffuser plug-in that can be calming to many dogs. You can get this at a vet's office, online, or in some pet stores. I would consider a calming supplement such as Zylkene or Composure (also available at vet's offices or online). I would be sure that Marilyn is still getting attention from the family and that she is able to get away from/escape form the other dog if she doesn't want attention from him. Provide her a safe sleeping area and separate food and water so she doesn't feel any need for competition between the two dogs. If the problem continues or she develops any of the symptoms I mentioned earlier (these could indicate illness) , she should see her regular vet.
