I myself use frontline plus... and it works for me. BUT frontline top spot does NOTHING for my animals. do you know which one you used? I think I would ask my vet before I put another dose of chemical on him But my friend told me about this... and they said it works within 30 mins and its called capstar... you can get it at 1800 pet meds i know. Also I was reading where someone tried bathing them in dawn... there is a thread here about it. I would definitely ask the vet and see what he would suggest! Goodluck |
