After just two doses of Chlortrimeton at half the
dosage the vet recommended, she shows no signs
of soreness now. She began sneezing 12 days ago, and
the muzzle soreness appeared maybe five days ago. She is back to eating all
her food and seems normal again.

(The vet recommended 4 mg tablets of Chlortrimeton
cut in half and given as 2 mgs every 12 hours. I gave her 2 mgs every 24
hours for 2 days because she is so little and I think they often
overmedicate.)

Thanks to all who offered advice and good wishes.
