## Description

The new and improved Advantage II now offers flea and lice protection for your dog. Flea and lice treatment with Advantage II gives your dog a safe solution that only needs to be applied once a month. Dogs and puppies older than 7 weeks and weighing over 55 lbs are fit for this flea and lice killing formula. This formula will kill fleas completely by eliminating their eggs and larvae by using a variety of ingredients and compounds. It contains a fast-acting formula that kills fleas quickly and prevents them from returning. Advantage II uses the compound pyriproxyfen to kill fleas and other insects by interfering with their maturity cycle. Targeting insects, pyriproxyfen does not affect mammals. Other flea killing properties like adulticidal, larvicidal, and ovicidal kill fleas and prevent them from emerging again. Imidacloprid paralyzes fleas so they are killed before biting your dog and also reduce the incidence of flea-related allergies.

**Q: I've just applied to my flea infested dog :( How soon can I bathe him?**

## Customer Reviews

### ⭐⭐⭐⭐⭐ Oldie but a Goldie!
*by J***E on July 26, 2019*

I have been using advantage products for over 10 years and both cats and dogs and it works wonderfully! Both the cats and dogs were located in the south where there are a lot of sand fleas and ticks. Never one single problem. All the hype about fleas becoming immune to it, is just hype to encourage you to buy ingestible poison for your dog to eat to kill the fleas. Commonsense alone should tell you there’s something wrong with that picture…

### ⭐⭐⭐⭐⭐ Have used Advantage for years
*by H***K on July 29, 2021*

I used to work at a vet clinic, with resident pets and rescues. They treated the pets monthly, always with Advantage II. It's the most effective OTC product for killing fleas (as well as larva and eggs, so you don't have to worry about more hatching). I buy the XL Dog size and split the doses between a large dog and 2 cats. Treat your pets every 28 days or so and you'll never have to worry about an infestation in your home.

### ⭐⭐⭐⭐⭐ Good deal

Good product for my animals
