Description

Say hello to flea and tick control you can count on! With the PetArmor® Extend™ Collar for Large Dogs (above 18 lbs.), you can protect your dog for up to eight continuous months, without a prescription. This scientifically proven collar kills and repels fleas, ticks, and lice through contact, so they don’t even have to bite your dog to die. It starts working 24 hours after the initial application.

Made with the #1 vet-recommended active ingredients, the Extend Collar delivers effective protection that keeps working even if your dog gets wet. The active ingredients, imidacloprid and flumethrin, are slowly released from the collar and spread into your pet’s skin and coat, delivering long-lasting, water-resistant protection.

With season-to-season coverage, you can have peace of mind knowing your dog is shielded with the hardest working collar that money can buy.

Cat doesn’t like collars

[This review was collected as part of a promotion.] The material is plastic and very durable. Not sure how effective it is as it’s still pretty cold here in Michigan and my cat doesn’t go out much when it’s cold. Cleaning it seems to be easy enough. Not sure about the safety or value as of yet. Will update as he wears it.

A nice adjustable flea and tick collar

[This review was collected as part of a promotion.] This PetArmor flea and tick collar is nice, it very easy to put on my dog and I like how easily adjustable it is. There is quite a bit that hangs off but that can easily be cut off or tied to collar again in case readjustment is needed. I’m pleased with the results of PetArmors flea and tick collars. They last a long time plus I’ve noticed my dog itches less and I rarely if ever see a tick on him.

Looks good

[This review was collected as part of a promotion.] Very nice! I haven’t had one of these since like 2004 for my cats, I have dogs and never used one of these for them. It’s definitely more fancy than I thought it would be. Since my dogs are going to go out more, this came in handy. I can’t wait to use it more. Thank you.

Convenient

[This review was collected as part of a promotion.] The collar length was perfect for my dog with plenty extra length. The color has a slight odor but not strong g and it went away after 2 days. The instructions where very straight forward and easy to use.

So far so good!

[This review was collected as part of a promotion.] Installation was simple, sizing was normal for my cat. She’s been wearing a couple of days and so far so good. Looks to be normal material and size for flea/tick collar.

Does the job so far

[This review was collected as part of a promotion.] Works great so far! The collar is easy to put on and my baby doesn’t mind it at all. Fleas are annoying and preventative care is what I’m all for. For what it does, the collar itself doesn’t look bad either!

Good for fleas but might affect your pups skin if

[This review was collected as part of a promotion.] This was super easy to use from the get go. You just unroll it, fit it on your dog and cut the excess off. I must say, there aren't any fleas on her anymore. We live in apartments and the area where they use the restroom isn't treated all the time so there's fleas and she's typically stuffed from them. That being said, this collar helped with that. However, after about two days I noticed there area around her neck started turning really red. No where else. I use other flea collars on her and this hasn't happened before. 😬

Easy to use and works

[This review was collected as part of a promotion.] My cat although looks like a kitten she is a full grown 10 yr old cat. Her growth was way under. We found her as a baby kitty yrs ago behind a dumpster with no momma so we adopted her. She stays outside and in both so we do get fleas and ticks. This collar is non greasy like most, no particular smell at all and has been working great. Easy to use, just open, measure on cats neck then you can adjust it to fit by cutting any excess off. Mollie doesn’t seem to mind it at all so must be comfortable for her. We haven’t had a problem with either fleas or ticks. if I find one it’s dead. This collar last up to 8 months it says which is really good for a collar

Rousy

[This review was collected as part of a promotion.] I received this product for free from an influencer for my honest review. Rousy is always outside. At first, she doesn't like it, and she scratches. At this time, she does not pay attention. I feel it is good material I don't know any bugs yet. We'll see when the time passes.

Dent in a pinch

[This review was collected as part of a promotion.] This brand is reasonably priced. This collar didnt seem to help with fleas that I noticed but I also use topical flea treatment on my dogs. The one thing I noticed is this collar has an odd smell that lingers. I am sure its the medication that's on the collar. The one thing is the collar doesnt fit a typical smaller dogs neck as its a bit short.

Cat didn’t love it

[This review was collected as part of a promotion.] Works well but my cat dislikes the collar. I would be weary of purchasing if your cat is sensitive to collars, the product itself works very well and was really easy to take out of the package and start using.

Convenient Longer Lasting Alternative to Flea/Tick

[This review was collected as part of a promotion.] Works great. Have used these on my family cats in the past. They are a great alternative to monthly flea and tick dropper treatments which can be difficult for both cat and owner lol. It’s nice to be able to put it on and not have to worry for 6 months about doing anything else to protect against fleas/ticks.

Be careful of ingredients if your dog is sensitive

[This review was collected as part of a promotion.] Couldn’t use. My dog is allergic to some of the ingredients in this collar which is why I do not have a picture of it on him. I’m sure it works for others but not him.

Easy protection collar!

[This review was collected as part of a promotion.] I used the colar with my Persian cat and fount it very convenient because the fit is adjustable and leaves the two fingers space, so comfortable. The assembly is simple, just unroll, remove tabs and secure. The instructions are clear. Overall, a practical low-maintenance option for flea and thick protection

Easy use

[This review was collected as part of a promotion.] A simple flea collar for short term use. It seems to work at first, but loses validity rather quickly. This would work better in tandem with another flea product. Easy to put on, stays on with the clip and comes off easy with minimal effort.

Can it withstand my 80 lb dog scratching?

[This review was collected as part of a promotion.] These flea collars are very easy to adjust on my large dog. I love that they are thick and fasten well because my dog is not a fan of flea collars. Maybe it will stand up to his scratching at it.

[This review was collected as part of a promotion.] Love this brand and it’s so easy to put on my cat. She’s not a massive fan of collars but she doesn’t mind this one because it’s small. Highly recommended to protect your cat from outside

Make sure to measure your dog’s neck

[This review was collected as part of a promotion.] This seems to work fairly well, like it better than the liquid that you put on the back of their necks that is super oily and caused my dog to loose hair temporarily in that spot. The collar is well fastened and it does not come off, which is good so I only have to take it off every 3 weeks for bath time. The only complaint is that the sizes should take into account the breed, my pug is small, but I guess her fat neck is quite big because it did fit in the last notch, if she was any bigger she could have not gotten into it… not fat shaming her, hahaha
