Tsar over at the Portuguese Water Blog is the member of that very extensive pack who is most like our beloved Thor. He's a quiet, solitary kind of guy, referred to by his Mom as a "Cat-Dog." Isn't he a great looking fella?
Tsar has developed some unspecified neurological disorder very recently. Sue, you and Tsar are in my thoughts, and I'm hoping for some better news very soon.
Thor would have sent the same loving thoughts your way.
