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 pet after application?

Dogs can swim or be bathed after application but it is recommended that you wait 24-48 hours after application.

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

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.

  • Not a Bad Product

    By on

    It seems to be working well. At the beginning, I was very angry that I had purchased this product, because my dog kept scratching more than he ever had before, even after I applied this. Then I realized that the poor thing was covered in mosquito bites. If you don't live in a mosquito-heavy area, this should be fine. However, if you have mosquitoes, you will need to get a different product.

    Chewy sent me this to review! I liked it because my dog stayed flea and tick free for the duration of the 30 days! I found two dead ticks when brushing her out! I recommend this as a good alternative to prescription flea and tick medication. Make sure you part your dogs hair all the way down to the skin before applying the topical medicine. Also I really like that it’s waterproof and you can even give your dog a bath and it still works as long as it’s after the 24 hour mark of when you applied it!

  • Worked for me

    By on Top 500 Contributor

    It's a bummer to see how many people have had a negative experience with onguard. My dog was previously on a tablet flea medication but I kept finding fleas on her and was getting frustrated. I tried onguard when it was 50% off and was pleasantly surprised to not see another flea on my dog again.

  • Great product, excellent customer service

    By on

    I was impressed at the ease of dealing with this company. The customer service was excellent and took care of my needs, even though the mistake in the order was my fault, not yours!! Onguard appears to be working very well with no vomiting as has happened with other products.

  • Does Nothing

    By on

    I ordered this item for my dogs, thinking it was close to a brand I had that I knew worked but chewy does not carry. I just put on two of my dogs (which at the time they did not have fleas) as not now they do. This product did absolutely nothing!

    I like the ease of application of Onguard. So far it has protected my two dogs from fleas and ticks. I like to alternate brands so that one doesn't lose its effectiveness.
