She seems to be very itchy. She's rubbing her nose on everything. Now I'm leaning towards the nasal Bordetella vaccine as the cause. Ugh, I guess we'll never really know. She's also scratching her ears, and they are clean, so maybe she's just itchy all over from the other shots and/or the anti-imflammatory. I see now why the Benadryl is given. I wish the vet would have mentioned that. I would have picked some up on the way home.
