Oh, my gosh, I missed this thread, too! Even living where I do, I have never known anybody whose dog got Valley Fever. The Northridge earthquake stirred up those spores and we did hear a lot about the disease after that. My friend's son had it but is fine today.
Pops, I've taken Tramadol for years and it has a mood elevating effect in addition to the pain relief. That's a good thing and I hope Calvin shows signs of feeling better. You know you've got all the good vibes I can possibly send out to the Universe for Calvin. Be strong.
