I'm hoping someone can give us advice. We've just discovered our border collie has his second tick in 3 weeks [sad]. He is a rescue dog and we frontlined him with spot on the day we found the first (2 days after we got him). I thought that the frontline was supposed to stop ticks [confused]. Are we doing something wrong? Is there anything else we can do? Eww I've just begun to accept dealing with headlice in the children and now this [grin]
