About This Item

Details

  • Parasite Protection: Selarid is an FDA approved, once-a-month topical application that kills adult fleas, prevents flea eggs from hatching for one month, and prevents deadly heartworm disease in dogs.
  • Multi-Pest Treatment and Control: Beyond fleas and heartworm, Selarid treats and controls ear mites and sarcoptic mange, and controls tick infestations due to the American Dog Tick.
  • Easy to Use: The convenient topical application is applied to the skin at the base of the neck, in front of the shoulder blades, making monthly treatment simple for pet owners.
  • Cost-Effective: Containing the same active ingredient (selamectin) as the pioneer, Selarid offers the same efficacy at a more affordable price point.

Same Quality Without the Name-Brand Price

With the same active ingredient as Revolution® (selamectin) topical, Selarid® (selamectin) topical parasiticide offers comparable parasite control at a lower price.

Year-Round Parasite Protection

It's not just for one season. With simple, monthly applications, your pet will be protected year-round from heartworms, fleas, ear mites and other common parasites that threaten their quality of life.

Cuddle Without Concern

As a non-greasy topical parasiticide, Selarid® (selamectin) offers peace of mind for dog owners. Snuggle up to your pet anytime, knowing they're effectively protected from heartworms, fleas, ear mites and more.

End the Cycle of Infection

Selarid® doesn’t just treat parasites, it effectively breaks the pests’ life cycles to maintain protection month after month. Selarid® breaks the heartworm lifecycle in dogs by killing L3 and L4 stages, thus preventing development of adult heartworms. Similarly, Selarid® breaks the flea life cycle by killing adult fleas and preventing flea eggs from hatching.

Surprisingly effective for the price

With a fast growing giant breed, this was a great option as he graduated from 45 pounds up to 78 pounds in just a few months. It has been effective against fleas and ticks. He is a livestock guardian dog and spends a majority of his time outside in the pasture.

This stuff is half the price with all the protection! Fleas, ticks, heartworm, et., all for about half the expensive brands. I've been using it for years. With multiple dogs it gets pricey to keep them protected. You'll never regret using this. Besides, vets are getting so tricky about mal by you buy from their shelves at their prices if they stock your brand. Most don't even know about this stuff, so they have to give you a prescription to find cheaper brands.

Neurotoxic effect on cat even at 1/4 of dosage

I used the lower dosage .75 for 5 to 15lb cats for first time on my cat of 20lb. Nearly instantly following application his ear began twitching and lowering sideways

I used the lower dosage .75 for 5 to 15lb cats for first time on my cat of 20lb. Nearly instantly following application his ear began twitching and lowering sideways down head with increasing scratching. This is deemed a neurotoxic effect. My vet had me bathe him immediately -full body-to lessen absorption through all skin multiple times. I can’t tell you how anxious I was to at he would have a seizure or die. Luckily, for us, he got past it without another occurrence or something more severe. But I had also used less than HALF the liquid in the pack as a patch test. I never use chemicals but found a flea on him likely our dog brought in. Prior to this this I was using diatomaceous earth, i since got vets best waterless flea shampoo foam, flea comb, and diatomaceous earth. Within 4 days no fleas on him. I did clean my house excessively- every cushion, under and vacuum and wash daily for two weeks but I seemed to avoid an infestation by being so diligent. No fleas on any pets and all happy. I will never use a chemical again- even if we get a flea. The combination of diatomaceous earth and vets best foam worked in a very timely manner to break the life cycle with my excessive cleaning. I caution others given my expedience with Selarid.

Fantastic generic alternative to Revolution

This generic version of Revolution is just as good as the name brand. The cost was almost 50% less! I love that this version has a much lighter chemical, medicine

This generic version of Revolution is just as good as the name brand. The cost was almost 50% less! I love that this version has a much lighter chemical, medicine type smell. Easy to apply. My boy is sensitive to a lot and he has no side effects from this. We use to help with an overproduction of mites that cause mange. I recommend over most other topicals of this nature. Shipping was quick, they filled very fast as well. No issues whatsoever. Thanks Chewy!

I like this product because it is easy to apply - no fighting my dog to get her to swallow a big pill. So far we've had no issues with fleas, etc. in over two years

This is a good product that keeps our furbabies protected. Chewy was on top of the auto refill by contacting our Vet, contacting us that it was shipping out and on the way. We didn't think about it when we only had one left. Great product, Great company!

Needed to find something less expensive. Since topicals were widely used years ago, thought I'd try it. Easy to place and my pup had no reaction. So, hurrah...I'm saving about $300 this year.
