She's around 30lbs. I gave her approx. 1/3 of a 25mg capsule. She's not having issues breathing, appetite is normal, but there is sores and discharge on her nose, which is pretty swollen. I'm scared that it can't wait till Monday and there's no place open tomorrow (Sunday)
As it turned out, I got the dog to the vet ASAP and she had a secondary infection that we're now treating. Thank you for the help.
