I've been having trouble with Ticks getting on Dixie even though she gets Frontline Plus. So today I sprayed her down with a 50/50 solution of ACV and water. She has been scratching her self silly due to the ticks also and after being sprayed she isn't scratching as much. We went outside earlier and she didn't get a tick on her also. Hopefully this helps and if it keeps working I will report back.
