Thanks for the advice, KYS. We did remove the ticks as soon as we saw them. I was just wondering why they were there, two days after I had already applied the Frontline. They were still alive.

Good idea about calling the # on the package. I never would have thought of that.

I do get Max a Lyme vaccine every year, thank goodness. It's due again in June. I hope it's still working!

I didn't realize ticks were out and about this early in the year. That was the last dose of Frontline I had. I ordered some for Max, Aspen, and Toby and gave Aspen and Toby theirs today. Aspen just got her second Lyme shot a few weeks ago (the first year it's 2 shots). She had a big tick on her today.

The ticks are just terrible up here, and Lyme is rampant.
