I use K9 Advantix, which I know has permethrin in it, but now I'm a little concerned. I used to use Frontline Plus but last summer, he got sooo many ticks on it and even got Lymes disease. K9 Advantix is the only thing that has worked for us to keep the ticks, fleas and mosquitoes away from him... should I give Frontline another try? I just really wanna keep ticks off him, but I also don't wanna hurt him by giving him medicine with permethrin in it! |
