This fast-acting topical treatment kills all life stages of fleas and ticks on dogs at least 8 weeks old and ranging from 6 to 22 pounds, and helps control infestations of chewing lice and sarcoptic mange mites. With the same active ingredients as FRONTLINE Plus—fipronil and (S)-methoprene—Onguard breaks the flea life cycle and rids your pet of fleas that can cause flea allergy dermatitis.

FAQ

How does Onguard protect my Dog and kill fleas and ticks?

Once Onguard Flea & Tick for Dogs is applied, it stores itself in the oil glands in your pet's skin. It then self-distributes continuously for one month to your pet's hair and skin through the hair follicles, killing fleas and ticks.

How often should you apply Onguard Flea & Tick for Dogs?

It should be applied once per month to protect from fleas, ticks, and chewing lice.

How old does my dog need to be/or weigh to use Onguard Flea & Tick for Dogs?

Your pet should be at least 8 weeks old and at least 6 lbs to use this topical treatment. Please use the correct product for your pet's weight.

Can I use the same size of topical on my two dogs or can I buy a larger size and split the product between my dogs?

We always recommend using the proper size product for your pet. The active ingredients are in a liquid form and there would be no way to certain that you applied the proper amount of actives for your pet. This could lead to ineffective pest control or an overdose for your pet.

How long does Onguard take to dry?

We suggest keeping your pet off of carpet and furniture for around 2 hours to allow the product to dry.

Is Onguard Flea & Tick for Dogs waterproof? Does that mean pets can swim after application? Or can I bathe my dog after application?

It is recommended to wait 24-48 hours after application prior to your pet getting wet or being bathed. If this has happened the effectiveness of the product may be reduced. You can bathe your pet with a dishwashing liquid to remove any of the product that is still left, wait 24 hours and another application can be applied.

Can I use it if my pet is on medication?

Before using Onguard Flea & Tick for Dogs, ask your vet about possible interactions with any medications your dog is taking.

Can I apply Onguard Flea & Tick for Dogs on my cat?

No, never apply a dog product on a cat it is always recommended to apply the proper product for your pet.

I applied Onguard Flea & Tick for Dogs on my Dog, why am I still finding fleas?

You may still notice a small number of fleas after application as fleas rise to the top of the Dog’s haircoat as they die. However, if your dog had an infestation of fleas prior to application of Onguard, it may take a month or so to break the flea lifecycle and get rid of all fleas entirely. We also recommend treating your home to help avoid your dog picking up more fleas.

Onguard
2 Powerful Active Ingredients

Onguard uses two active ingredients that are commonly used to protect dogs from fleas and ticks. Fipronil and (S)-methoprene work together to stop an infestation in its tracks and prevent future ones. Fipronil kills adult fleas, ticks and chewing lice and aids in the control of sarcoptic mange mites. (S)-methoprene prevents reinfestation by eliminating flea eggs and larvae by disrupting their maturation. Together the two create a highly effective flea and tick preventative treatment.

One-Step Application

These topical flea and tick treatments are easy to apply and effective for up to 30 days. Each box contains six applications so you can keep your pet protected for a full six months. Simply apply it between the shoulder blades of your pet, and the long-lasting solution will keep protecting them from fleas and ticks. The formula is both waterproof and sunlight-proof, so you don't have to worry about reapplication throughout the month.

  • Seems to be working

    By on

    I saw a couple fleas on my dog and immediately gave both of them a bath. After 3 days I applied the OnStar Flea and Tick Protection and haven't seen a flea since! I noticed no side effects, like lethargy or nausea, which I usually see after after spot on applications. This product is worth the money!

  • So far, so good

    By on

    Being on a fixed income makes it difficult to adequately provide pre tentative care for all my pets. This product has the same ingredient as the more expensive name brand, and so far, has worked just great. My dogs tolerate it well and it's easy to apply. I'm glad I've found Chewy and glad I've found this product.

  • It Works and priced Right!

    We treat our fenced in yard with flea and tick granules, however we were going on vacation with our fur family. They were totally protected from those nasty flea and ticks in the mountains.

    Unlike other, topicals, it seems to be working well. Very happy as I've tried all topicals (I think), and I don't like poking pills down my animals every month.

  • product is fine but damaged package

    By on

    I purchased Onguard Flea and Tick treatment for my 18 lbs dog. I used Frontline for almost 5 years, and i changed it to Onguard because Chewy recommended it. Honestly. i do not really know the difference between Frontine and Onguard, but this product has light smell then other. the product is so far so good. when i receive the package, i felt really bad because it damaged in packaging. it seems like someone opened it first.. this is not for me, this is for my pet...thus i contacted Chewy to check. Chewy solve my problem within 2 mins! they shipped new product right away. i always satisfied with Chewy Customer service!

  • Tick control but not preventative

    By on

    I have a serious tick problem and no fleas. I was a little concerned at first because it took at least 48 hours before I found the first dead tick. Since then it has worked fine at killing ticks on my 2 terriers. This product does nothing to deter ticks. My dogs still bring live ticks into the house. Before they die from the On Guard treatment I have found live ticks on furniture and myself when my dogs snuggle with me. I may try a different product that offers a deterant next time.

  • Works amazing!

    By on

    I've used many other brands, but Ongaurd is amazing! I brought my dog into a heavily wooded area and all the other pups got so many ticks, but NOT my Shiba! She stayed tick and flea free the entire time. Highly recommend.

    I've been using this for 6 weeks. So far no signs of fleas or ticks on my dogs. No signs of skin irritation from product. We live on an acre of wooded land that has lots of bugs and wildlife passing through.We are located in SE Texas. I decided to try this product as the K9 Advatix II was not working as well as it used to. I had a vet say that some fleas become resistant to certain chemicals over time. So far I am please with this product. I should note that I make sure to wash my dogs with a flea/tick shampoo and apply this topical a few days later during flea season. Also you can treat your yard with OFF or Cutter brand yard sprays. They work really well if you are having a flea/tick infestation I've been using this for 6 weeks.
