Highly Recommend for Dog Owners

It's really easy to apply and the water-resistant feature is a bonus. I love that it kills flea eggs and larvae and also provides full-body protection. It's suitable for dogs of all sizes, thanks to the adjustable size. The fact that it prevents reinfestation and offers long-lasting protection is what appeals to me the most.

Fleas No More

Within a day of putting these on my dogs, their scratching and biting decreased by about 95%. I was kind of skeptical at first because I've always used topical or pills. I was pleasantly surprised.

Six Months of Protection From One Collar

A flea and tick collar changes the routine: fit it once and it works continuously for six months. No monthly dose to schedule, no reapplication to miss between grooming days and long weekends. Just steady, head-to-tail protection your dog wears the whole time.

Head to tail

Coverage That Goes After the Whole Flea Cycle

Killing adult fleas is only half the battle. PetArmor® Plus targets fleas and ticks along with flea eggs and flea larvae, helping break the cycle before a few bites turn into a full infestation at home. The active ingredients, Deltamethrin and Pyriproxyfen, work across your dog's whole body.

Best flea prevention!

The media could not be loaded. I really love this product. My dog suffers from skin conditions and I feel like every time he wears the collar he’s great. As soon as I try something else, like medicine, his skin starts to deteriorate and always gets fleas. Seriously a great product and I buy every three months. Highly recommend! Also it doesn’t smell bad at all.

5.0 out of 5 stars Not a single flea or mosquito bite

Hi my name is Shadow. I am a Belgian malenois mix. I had A terrible reaction to frontline, so daddy bought me this premium dog collar for fleas and ticks. I live in Maine where fleas are a major problem in warm weather. With this collar I don’t have a single flea or tick or mosquito bite. Daddy said mosquito’s are a major problem with tapeworm for dogs. What is cool is I can lie on the lawn and every ant and any bug stays far away. The collar makes me smell nice like baby powder. My daddy is highly allergic to flea bites when they live in the rugs so fleas are unacceptable. He highly recommends this collar. He makes me stay with him when he does outside chores as I keep mosquitoes far away. It really works a miracle just like the 50 dollar flea collar does

As good as the more-expensive ones.

We tried the cheapies and they did nothing.We used to buy the high-priced Seresto ones. They worked, but got to be too crazy-expensive.TBH, these aren't exactly -cheap- either... but they're notably less. We change these out on our dogs every six months and never see a flea or tick.Seems a good middle-ground. So good-to-go in my book.

An Incredible Solution for Flea and Tick

This is an incredible product because it's water-resistant and kills flea eggs and larvae. Gives full-body protection to my dog. The inclusion of two collars is a huge bonus, offering one full year of protection. The long-lasting protection and vet-quality ingredients assures me it's the best choice for my pet. This is the best there is for flea and tick prevention and protection, hands down!

Works well against ticks, very lengthy

I like that this brand is not as expensive as others but works just as well. I put this collar on my dogs whenever they go outside into the grass and they have never come back with ticks in their fur. The smell is also not as strong as others and there is no powdery residue (I would still recommend washing your hands after touching it). The length of the collar is extremely long for a small dog, so I like to order 1 and cut it in half and use one half on each of my dogs.

My Furry Friend's New Favorite Accessory

This is a really great purchase because it provides full-body protection to my beloved pet. It works just great! Now, those pesky fleas and ticks have met their match. Gone are the days of worrying about my furry friend being pestered by these unwelcome guests. This collar is like a knight in shining armor for my pup. So folks, if you're looking for a simple, effective solution to keep those bugs at bay, this might just be it.

Long-lasting Protection and Peace of Mind

This product has been exactly what we needed to keep those pesky fleas and ticks at bay. Not only does it last an impressive 12 months, but it's water-resistant too. So, be it a rainy walk, a doggy bath or a splash in the puddle, the collar keeps doing its job. Talk about a collar that works overtime! Our furry friend is now happier and itch-free, and we couldn't be more relieved.

A Rover's Relief but a Bit More Durability Please!

I recommend this product, it's quite the lifesaver for my dog. I'm thrilled that it kills flea larvae, a major step towards a flea-free home. The adjustable size and easy application were another win - it fits all, from my Chihuahua to my Great Dane. However, I do wish it was a touch more durable. Overall though, it's got my paw stamp of approval!
