I've used Frontline for a long time, and it just seems that this last summer I was having to dose Taylor about 3-3 1/2 weeks after the previous dose to keep on top of things.
I've tried the Sentinel product once and it didn't give me the desired results. I'm pretty fussy about bugs of any sorts, so I'm not sure what I'll be using next if the Frontline craps out on us.
