I use Frontline and found the same problem. It use to work well then it stoped workin . Well I found out that there is sort of a generic out there actually counterfiet Frontline. It comes in a similar package but if you look at the fine print it is not in English but rather many different languages. Most people don't notice because it looks pretty much the same but it is actually different. Only the one that is made in USA is the true Frontline and it does still work. The other has similar ingredients but different enough not to work as well. |
