Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Questions & Answers

8 Customer Questions

How is it applied?
Answer by ChewyMar 09, 2019
After the narrow end is cut off the tube, invert the tube over your pet and use the open end to part your pet’s hair. Squeeze tube firmly to apply all of the solution to the pet’s skin as a spot to the pet’s back between the shoulder blades.

Do the fleas/ticks have to bite to be killed?
Answer by ChewyMar 04, 2019
This treatment kills fleas and ticks through contact with your pet's haircoat. They do not need to bite the pet.

Can you bathe your dog after the treatment has been on for a week or so?
Answer by ChewyDec 08, 2018
After application you must wait about 24 hours for the product to fully dry before allowing your pet to get wet.

My dogs weigh 78-82 lbs should I use the extra large Pet armor for the 88lb + or the 88-lbs?
Answer by ChewyMar 20, 2020
This treatment is suitable for dogs 45-88 pounds.

Just as good as more expensive brands

I live in the country where ticks and fleas are everywhere. Since we switched from the more expensive brand to PetArmor plus, we have not seen a change in coverage. My 2 dogs never have fleas and ticks. I highly recommend this product.

Great option!

This was a great option for my CKD dog who was in Stage IV (late Stage IV). Being able to buy a single dose worked very well.

The absolute best!

We used Frontline on our first Lab and started it on our second, but he was inside and we were still pulling ticks off or getting ticks on us that crawled off the dog. Switched to PetArmor with reluctance and have never even considered going back to Frontline or trying anything else! It is amazing! We’re now using it on our third Lab! Never see a single flea and if we do find a tick it’s because we failed to put the dose on as needed. Can usually go 6 weeks, but beyond that you may see a tick or 2. We are very rural so this stuff is much appreciated!! Have repeatedly recommended to others who have loved it too. Excellent price and above expectations for performance.

I wish I could say this was great but both of my dogs had reactions to it. It’s no one’s fault sometimes this happens. Love Chewy though!!

Dead Fleas, Dead Fleas, whatcha gonna do....

...whatcha gonna do when PetArmor comes for you? The fleas on my dogs fled down their spine carrying white "I surrender" flags before leaping from their tail. I applied this to my Hound and Lab in the morning and by the evening, I was combing off dead fleas. This worked fast and the verdict is still out on how long it will last. This product can be tricky to cut open but is easy to apply and not as greasy/runny as other products. It dried fast, which is fantastic since I have a cat that likes to smoosh against both dogs. It has a surprisingly nice scent and not that horrid pesticide smell.

BudE Surprised

First of all I messed up and got the large dog I have a matipo 20 lbs. Figured okay I got it I would use one third of the container found out one container on a 20 lb Maltipoo Works great no side effects please ticks are gone no itching no scratching no uncomfortable feeling for BudE. It may be more than what's recommended but it works ready to buy again with highly recommend it I waited after purchase to see if it would work not sure being or large dogs how it would affect smaller but after trying the half tube took a chance use the full tube like I said it works great.

Pet Armor2

This products is substandard does not keep fleas off for one month maybe at best 2 weeks. Even though more expensive went back to Advantage plus. In the end Advantage was cheaper because I only have to use it monthly instead bi-weekly.

Been using pet armor for over 12 years. Never had a flea or tick on my animals. Never had a negative reaction either. Price is right also.

PetArmor Plus Flea & Tick Spot

Well my fiancee decided to buy this product for our dogs and cats when we had flea issue. Like everyone else money was tight, so the price sounded right on this product. The vet was against this product from the start. Sometimes the vet has list products they push which is okay. We noticed yes some fleas where dieing but the problem was not going away. We invested in soresto collars and it was highly recommend. Our problem fix it self in like 24 hrs and everyday it got better. We have 5 pets all different ages and breeds. Dogs and cats. I recommend soresto for both dog and cat.
