Mental health during confinement during heart worm treatment

Our newest dog came to us with heart worm. While he likes to run and play with our other dogs the vet has us confine him during the many weeks of treatment. The dog does not understand and seems to think he is being punished for something he did not do. What can we do to improve his situation?

 

Answer from Dr. Gaylord Brown:
Allow the dog to be with you in a non-active manner. However, you must keep him quiet for his own good when you are not around. Mild sedation may be required. The alternative is possible death.
