Cheap Advantage Flea Control for Dogs (Six Dose (6-applications))

Customer Ratings:

we have used Advantage for over ten years. In Jax, FL it no longer works. days after treatment we see fleas on our dogs and cats and flea eggs in house. This has been happening consistently for the past year. I would not recommend advantage, use Frontline for dogs or frontline for cats instead. Advantage is a waste of time and money if you live in Jax, FL where the fleas are resistant and immune to its effects.

I've always used this. Never had a problem with flea immunity. I'm allergic to fleas, so I'd know if we had them in our house. Works amazingly well. I'm ashamed to say I just bought a six pack from my vet for $100, and wrote on the box the date my dog needs it...so I can't return it. Amazon prices are better!
