I didn't like Frontline on Max.
Found 6 ticks in one day.
We have been using k9 Advantix now for 1 1/2 years... found only one tick ever and it was dead already
I also have Mickey on it.
K9 Advantix prevents ticks from attaching and getting on your pup.
Frontline the ticks have to attach on your pup to be killed.
