I'm so sorry about this. Adopting or fostering another hound might ultimately be what works to ease Henry's pain (and yours) But until you are ready, classes are a good idea. Our local trainer has such a mix of fun and informative classes, and one that the hounds really enjoy is "Doggie Line Dancing" - it doesn't matter if you have two left feet or four left paws, it's just fun. There must be something like this in your area. Just getting out and socializing, or a walk on a new trail, can be very uplifting. You might try Janet Marlow's CD "Zen Dog Music & Massage for a Stress-Free Pet" - I leave this on all day while I'm at work and definitely during a T'storm, it really does seem to keep a calm environment. Rescue Remedy can be incredibly helpful, also.
