Hi. I am stranded by smoke and fire with a lady on hospice, so I can’t get to my vet. My 2 yo female Rottweiler, 90 lbs, who has a bad infection on her chin. It started as bad acne. She was treated before with antibiotics. The only thing I have in the house is an expired arc for clindamycin 150 mg. I want to give her 1 pill, twice a day, since I can’t get out til the end of the week, as she needs antibiotics now. I am afraid of side effects, but she needs antibiotics.
