Learn More About PetArmor From Our Team of Experts
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.

Protect Your Dog With PetArmor Plus

Easy To Get: No prescription needed

Waterproof Formula: For all-weather outdoor play

30-Day Protection: Apply monthly for year-round protection

Breaks The Flea Lifecycle: Kills fleas, flea eggs, and larvae, plus chewing lice and ticks

Facing An Active Infestation?

Here’s what to do:

1. Treat Your Pet: Kill fleas on your pet with a fast-acting, non-prescription treatment.

2. Treat Your Home: Your home may be hosting many more adult fleas. Clean and treat your home with indoor and outdoor solutions.

3. Prevent: Protect your pet from recurring infestations by applying PetArmor every 30 days.

Choose the Right Weight Range

Each applicator is filled with the right amount for specific dog weight ranges. Tubes for smaller dogs contain less solution than tubes for larger breeds. Reapply monthly for ongoing protection.

How to Apply PetArmor Plus

1. Hold the tube with the notched end pointing up and away from the face and body.

2. Use scissors to cut off the narrow end of the applicator.

3. Invert the tube over your dog and use its open end to part the hair.

4. Apply directly on the skin, from the back of the neck to a point midway between the neck and tail.

Questions & Answers

9 Customer Questions

How is it applied?

Answer by Chewy • Mar 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 Chewy • Mar 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 Chewy • Dec 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 Chewy • Mar 20, 2020
This treatment is suitable for dogs 45-88 pounds.

For most of the summer I battled with fleas on my 5 dogs without success. I tried flea dips, flea shampoos and flea repellants without any luck. I finally tried Capstar and by the next day my dogs were flea free. I did repeat the treatment a month later as I saw a flea on one of my guys. I think it might have been a new generation verses a new flea from the outside. I am prepared to repeat again as needed, but I think people should be prepared to use at least 2 months in a row to make sure you are getting not only the fleas that are present but also those that will hatch from the eggs the original infestation have left before they are killed.

I've been using this for YEARS now. We lived in the city previously but, recently moved to the country. We heard that some parasites, especially in rural areas, have overcome some OTC flea/tick products. I was super worried about this but, a year later in the country, full of tall grasses and many creepy crawlers .... this preventative has continued to work beautifully! No creepy crawlers to be seen anywhere on my pups. Plus, the price is amazing. I have 4 dogs that need their monthly prevention and this doesn't break the bank! Thanks for making an amazing, affordable product!
