Thanks for your input. I decided to just wait it out and see if she was better by today and it didn't end up being that way. She still itched/scratched all night long.
I ended up taking her to the vet a little while ago and come to find out my little Marley has some sort of infection from all the flea bites and then scratching them. I feel so bad for her!
They gave her 2 different medicines that should take care of it rather quickly, thank goodness for that! The only good thing that I found out today is that she is FLEA FREE!
I want you guys to know that this is the FIRST time I've ever had to deal with fleas for my little Marley and it just kills me! I hate them, what purpose do they have! The Advantage Multi has been used on her ever since she was old enough to have it, I had never seen a flea on her until that day! Is there another flea prevention medicine better that Advantage? Please let me know if I should continue with it or change to something else!
