Do some Fleas become "immune" to given chemicals ?
I could go back to HeartGuard for the worm protection, then...
I have a choice, Comfortis, Frontline...
any others which someone has had good luck with ?
Or do I just need to buy a Hammer !

All of them have been on Trifexis for at least a year. |
I quit using Trifexis on my Shelby-Dale recently but for other reasons. We've never had a flea issue. Have you tried Sentinel (it's an all in one, also, but with Comfortis as the flea control).
Here's the deal: with Comfortis, you are sterilizing fleas - not killing the ones already around. If you don't have an infestation, it should work well. If you already have an infestation, I wouldn't go with that at first. I'd go with Advantix or Frontline. Personally, I'd go with Advantix as it also kills mosquitos. They both kill fleas, ticks, and lice.
I used Advantix on previous pets and it worked well.
