I just thought I'd post a little review about this stuff. My vet gave it to us last month instead of the Advantix that Jasper had previously been on. Initially, the applicator was a lot easier to use than the Advantix and the vet recommended it, so we were happy. Until about 2 weeks in, when we found 2 ticks on Jasp! A week and a half later, the tick total has come to about 6. We had no flea or tick problems with Advantix, and it was really disconcerting to find so many ticks on my little guy. I don't know if it's because Jasper's getting older and we're going out and exploring more places than we used to, but I just think it's unacceptable to find so many bugs on my pup when he's on flea/tick control. I went back to the Vet to get some Advantix and they told me they no longer carry it so I had to go to another vet because I refuse to put him back on that stuff. Just thought I'd post my experience with it for anyone who was interested.
