Thank you all for your help! I have done EVERYTHING that you all did.
Last thursday I applied the frontline plus.....
Friday- Came home, Put carpet cleaner down, vaccummed, washed all our bedding, her bedding, and didnt see any on her
Sunday- gave her a bath in the plain blue dawn- let it sit, rinsed, used some puppy shampoo/conditioner, thought all was good
This Tuesday, I'm sitting there playing with her and 2 fleas were on her head....

Went and picked up a capstar on Wednesday.......gave her a bath again, and thought we were good.
Well, went to a friends last night, and saw one on her head again, and her neck! friend gave me the spray- and so far this morning, i dont see any on her!?
Im so frustrated because I live in the basement of a friends house- its all finished down here, real nice- well the neighbors have a pit/beagle mix that is strictly outside dog- and they dont take care of her, plus they have 2 cats, well Jay (home owner) called my boyfriend yesterday saying that the little girl next door ( jay's gfriend watches their kids all week) had a flea on her- so they are assuming Fiona is brining them in, but in my case, im thinking that its their house with the fleas and bringing them here? its just frustrating cuz i dont want them to kick us out because of this...
