Lola may have a very serious problem and needs proper medical treatment. It is very possible that she could have distemper, nasal-sinus infection, canine influenza or kennel cough. Take her to an emergency vet, not the place she has been going to.
Since there is a possibility that this is distemper you need to seek veterinary help quickly so that she can receive the proper treatment. This is not a time to try treating your pet at home or going back to the same place that has not helped her yet.

Please let me know how you and Lola make out.
