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.

Our two German Shepards are in and out of the house all day. The drops allow them to be flea and tick free. They are easy to use and the dog children had no side effects other than taking a nap after the drops. However, they like naps so I'm unsure if the drops were the reason. Other than that, they are happy and free of those nasty little critters.

I purchased this brand for my four dogs & cat. This treatment was a waste of my money, it did not kill the fleas on any of them. We bombed our home, washed all of their linen & I’m going to have to Purchase more which is super expensive. I have 1 star because it wouldn’t let me submit until I did.

Useless and waste of $$

Bought the extra large size (89-132) for dogs to be sure it would work and one week later, still have fleas! Sadly, don't waste your money on this.

Economical topical treatment

I have four mutts, ranging from 46 pounds up to 100 pounds so treating four dogs can be expensive. Chewy prices are competitive for pharmacy needs.
