A scary morning

Well, I had a scary morning yesterday. Blast didn't want to get out of bed in the morning... very odd for him, since he's the one who wakes up excited to begin a new day.
He came downstairs & laid on the kitchen floor shaking - not a good sign. I couldn't see anything physically wrong with him - he went outside & did his business, no problem.
Anyhow, I took him to the vet where he had the once over. His temp was 40 & the concensus was that he's picked up a virus. No other symptoms except the fever.
He had a shot of anti-inflammatory medication & by the time we got home, he was already feeling better. Today, he's like a new man! Thank Goodness! I'll have to watch the other dogs to make sure they haven't picked up the same germ. It's good to have the crazy, playful Blast back!
