Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Sadly, we have recently started to see flea resistance to Frontline here in the UK.
If you would still like some assistance, can you tell me:
Did you put the same dose as before on Lola?
What did you worm her with? How long after the 2nd Frontline was that?
Are her gums pale/white or pink?
Has she had any vomiting, retching, or drooling?
ive had her a the vets shes ok
