We've been using Frontline Plus for ticks and fleas and Heartguard for heartworm. Both have worked great UNTIL this month. Fleas, so I've heard, are terrible. We put the Frontline on the 1st of the month (like we do every month) and found 3 fleas the other day. But, it says it's not supposed to weaken if they have a bath, but we gave her a bath the next day (without thinking) and I think that washed it out since it's worked for 8 years. So, we put another vial on last night and haven't seen any more fleas. I know you're not supposed to so soon, but we'll do it monthly on the 19th from now on.
