I fear my little dog has a serious problem, and until I get her to the vet tomorrow, are there any vets here?

My husband and I have a little Shiz tsu/Pekapoo mixed female dog that is less than two years old. On Tuesday evening, I adminstered on her for the first time the product "K9 Advantix" for fleas. I put this on her around 8 pm. During that same night around 3 am, she and other dog woke me up like they normally to do to be let out to go to the bathroom. When I let both of them out, I thought they both went. We keep "Cinder" in her crate at night, but she had continued fussing and whining till I let her back out again. She just went into the yard and sat then laid down in the cold gr. For the rest of the day Wednesday, after my before and after my husband and I got home from work, she continued whimpering and fussing and reaching for her hind end off and on. We called the vet, and since we live over 30 minutes away, they told us to bathe her in Dawn dish soap, adminster Benydryl every 8 hours, and also a tablet of Prednisone for 2-3 days, that we had from our other dog.
