Benadryl all around

Stephanie woke up yesterday with her face all swollen and red. She had started a new acne product, "Clean and Clear". So yesterday I gave her benadryl every 6 hours and she seemed better last night. But this morning she looked terrible, worse than yesterday. I took her to the doctor and they gave her some prednisone. Now Miley is having the same , sorta , problem. When I got back from the doctor, I sat on the couch and she kept trying to put her face in the blanket. Unusual for her. Then a little while later I notice her muzzle was bumpy , pink and hair sticking on end. So I gave her 1/2 a benadryl. She isn't happy yet. Pacing and keeps shaking her head. If the benadryl doesnt help by 3:30, I'm going to take her to the vet. So see, benadryl all around. Lol
