I just found a deer tick on my arm! It didn't bite me yet, it was just crawling. Now I feel gross and itchy! My uncle and aunt had a border collie that just passed away. They gave me what they had left of their Frontline. I use Advantix on Wolfie, but since I bought the package of Advantix, Wolfie has gotten heavier than the weight recommendations on the package. I decided to give the Frontline a try since it's the correct weight doseage for Wolfie. So far I have found 2 ticks on him in the past week, and now one on me. I am hoping I don't find anymore on him. I never found ticks on him while using the Advantix. I put the Frontline on him 2 weeks ago. Should I wait the full month before putting the Advantix on him? Would it hurt him to put the Advantix on him now?
