Pet Armor Flea & Tick Treatment: An Affordable Solution

The weather is slowly warming up here in Oregon, and for us pet owners, that means one thing: flea and tick season. My dog loves to roam around outside, but I don’t relish the thought of her picking up nasty fleas and ticks that are not only bad for her health, but bad for the cats and the rest of the family as well.



Up until now, flea and tick prevention has been pretty expensive. Frontline has been the flea and tick preventative of choice, but it’s just flat out unaffordable for many pet owners during these economic times.

I’m pleased to tell you there’s a new, more affordable solution! Pet Armor, which contains the same active ingredients as Frontline, is now available at Walmart and Sam’s Club at roughly half the price of Frontline.



Pet Armor is available for both dogs and cats in two formulas. The regular Pet Armor contains fipronil, which kills fleas and ticks for 30 days. Pet Armor plus contains fipronil, as well as S-methoprene. The S-methropene stops the flea and tick growth cycle, so eggs and larvae can’t turn into fleas and lay more eggs.

Application is easy. Just apply to your dog or cat between the shoulder blades every thirty days, and be free of fleas and ticks as long as you keep using it!

I’m pretty excited that I won’t have to pay as much for flea and tick prevention anymore! With three pets, the cost sure can add up!

  1. Hii is this actually as safe as frontline? i am very cautious about putting flea control on my two dogs molly and toby. i dont want anything to happen to them I love them so. thank you.

  2. Yes, the active ingredients are the same as frontline. I had the opportunity to talk to a vet about Pet Armor, and she said it was very safe.

    PetArmor™ Plus

    Along with fipronil PetArmor Plus contains S-methoprene. From the website.

    “Pet Armor plus contains lipronil, ” this is your quote, it is inaccurate. You should correct this so people are not mislead.

  4. I reread the post, so I could correct the mistake, but didn’t find it. This is my quote:
    “The regular Pet Armor contains fipronil, which kills fleas and ticks for 30 days. Pet Armor plus contains lipronil, as well as S-methoprene.”

    I did misspell fipronil, so I went back to correct it, but the s-methroprene has been there all along. Thanks for being concerned. Pet health is important!

    Our dog is 3 1/2 years old. We have used frontline plus on him since he was old enough to use it. He is a chow/lab mix. This month we found the Pet Armor Plus and decided to give it a try since everything we read compared it to Frontline and made it sound like it was Frontline’s generic.

    Monday night Bocephus was bathed and the Pet Armor plus applied as directed. This morning the poor dog loss a clump of fur from the application site and the area is very raw and inflammed. We called the number on the box and they couldn’t answer any questions about their own product. This product chemical burned our dog and they weren’t helpful at all. They were helpful in transferring us to ASPCA poison control, and their company has to pay the $20 fee for that call. We were informed to wash the area with soap and water and apply neosporin. ASPCA vet and our personal vet informed us we now have to watch the dog for seizures. Any sign of odd behavior and he will need to be rushed to the vet. Hoping the chemical burn is the only bad thing that happens to him from using PET ARMOR PLUS. Our vet said they don’t know why this stuff is even on the shelf. Saving a lil money isn’t worth damaging your pets health. We’ve used frontline plus and never had any problems and will be going back to it after this stuff wears out of his system.

  6. Jen, thanks for sharing your story. That’s horrible! My pets haven’t had a reaction at all, but I passed your comment on to the Pet Armor people, so they can look into it.

  7. I have recently had some really bad relations with this product.
    I have a 2 yr husky and a 10 yr Schnauzer. Both had really massive seizures after applying this medication.

    My Vet said the same thing as the previous poster here. He did not know what this product was even on the market.

    I’ve used Frontline Plus for years and never had any trouble.
    So I thought I’d try this “cheaper” product.
    well, Its not worth the pennies you save if your dog’s life is in jeopardy. I guess it boils down to which is more important.
    Your dog or spending a little more money.

  8. Lynnae thanks for bringing these two posts to our attention. Jen’s case is being followed by the ASPCA and we will monitor the progress of Bocephus. In response to Dale’s May 14 posting, we are deeply sorry to hear that you and your beloved dogs are having this experience. PetArmor is absolutely committed to the wellbeing of pets. You can rest assured, PetArmor™ has gone through rigorous testing with no side effects and we have not seen any adverse event like this reported. The product has also been reviewed and gained approval from the US Environmental Protection Agency. PetArmor does contain the same active ingredients in the same concentrations as Frontline.

    Please know PetArmor takes the wellbeing of pets seriously. If you haven’t already, please take your dogs to your veterinarian for a complete exam immediately. Please send us your and your veterinarian’s contact information. We respect the authority of your veterinarian and value the opportunity to discuss the situation further.

    We respectfully ask that you either call the PetArmor call center at 888-908-TICK or provide us with your veterinarian’s phone number so that we can have an ASPCA veterinarian follow up accordingly.

  9. ok I PUT THIS ON MY DOG OUTSIDE LAST NIGHT And my dog outside is doing good No prombles! But after reading these post should I use it on my Dog in side they are full blooded boxers ! I just dont want nothing happen to my dogs can any one let me know what to do >

  10. Connie, I have used it on all three of my indoor pets with no problems. I have also been in contact with the PetArmor people, regarding the above commentators that had problems, and they assure me that problems are rare, and they are following up on the above cases.

    I can’t give veterinary advice, but I didn’t have any trouble with my pets.

  11. karen busch says:

    Why does Pet Armour Plus list the percentage of their ingredients on the website anywhere? Is it even listed on the packaging? I would not try a product without seeing what the actual percentages are of all of the ingredients. Is there a place to see all ingredients with percentage of that ingredient? That is what people need to see to know how it will effect their pet.

  12. MARIE GUILLEN says:

    I’v used pet armor on both my cats and they still have fleas. Product doesen’t seem to work at all. My cats have it on now for about 2 weeks and still have the little pest.Don’t know what else to do.

  13. I’ve had no problems with this produce and I have used it on all of my 7 Rescues with all different breeds and weight. Sometime I think this is the Vets trying to steer us away from something cheaper. Last year my vet sold me for (over $300) a product for Flea and tick (I believe it was called Defender). When I returned home I did a search to see what other Vets said about this product. The only thing I saw that really got my attention was a few vets made thi statement “This product has really helped our Bottom Line”. I was furious because I am trying to save abused dogs and the Vet just keeps increasing their services. EVERYONE, Vet billls have gone up over 60% in the last 5 years…that is a statistic you can find on the internet. We need some changed.

  14. I just used this product on my three dogs and I have not had any adverse reactions and they seem to be free of fleas and ticks. If this turns out to work as good and it seems to , I have found my new flea preventative! The few people posting about problems with dogs after using armor. If they would do some research , all flea preventatives have a element of risk! Even Frontline and Advantage. So it may not agree with all dogs and cats so you may have to change again . I have used Armor Guard and am very happy!

  15. Jennifer says:

    I work at a vet clinic and asked my vet (and boss) about this medication, and she told me that the active ingredients are the same. However, it is the inactive ingredients that are not the same, but can make the difference. The ingredient in Frontline that helps it spread throughout the skin and protect the full coat, is what is missing from this product. So it remains to be seen if it will be able to offer the same protection as Frontline…

  16. save your does not work.i bought three packages for my cats.they were scratching the entire month .i spent another 100 dollars on frontline husband and i had to shave two of our cats because they were scratching so much after using pet armor. they were covered with fleas.i bought it because one of the big name animal rescues endorsed the product.what a should be ashamed of much did pet armor pay you to promote them.liars

  17. I agree with the vet’s employee that “the inactive ingredients” can cause problems for some in any product. However, the S-Methoprene listed in both products is what spreads the substance thru-out the skin and makes it waterproof. Did I misread or misunderstand the information? Anytime you put a medication into your body, or your pet’s body, you risk a reaction, ESP when that Med is a poison such as in these pet products; don’t you think?
    I am always anxious when medicating my pets; after all I am their caregiver.

  18. After reading the posts on this website, I did some research and learned that Pet Armor is made by Fido Pharm. According to the Pet Armor website, the US patent for Frontline has expired and the Pet Armor product is the generic equivalent of Frontline which is why the product is so much cheaper than Frontline.
    The websites for both Frontline and Pet Armor contain warnings about the risk of skin irritation and chemical burns from their respective products.
    Dogs are the same as people in that they can suddenly develop an allergy to a food or product such as Frontline or Pet Armor after years of problem free use. Additionally, the reaction to a generic product could be to the inert ingredients, not the proven active ingredients.
    I always do my research before trying something new and then I do a test dose with a smaller amount and monitor my dogs for any reactions. I use the smallest dose possible, as infrequently as possible, to minimize my pets’ exposure in the long term.

  19. ok so petarmor says save up to 50% compared to frontline plus .
    i canget frontline plus from healthy pets . 12 month supply $112.19
    free shipping . petarmor is $28.00 for 3 months. 12 months would be $112.00 so i save .19 cents ????
