This is Opal. A 11-12 week old SharPei puppy that came in the other day for her 2nd puppy vaccination. We don't see too many of these around. She came from the Atlanta area, I think.
Poor thing- about 20 minutes after getting her booster and getting back home- her head swelled up like a basketball. Her eyes were red and swollen shut, muzzle all swollen, etc. She had to get a shot of cortisone and benadryl. She was fine, and the swelling was about half way gone by the end of the afternoon after a benadryl induced nap. She could see a little.
Next time, she'll get a dose or two of benadryl before getting her vaccine.
