Good

[This review was collected as part of a promotion.] I t has a good grip, closes securely, doesn't open at any point, its scent is like lavander or something similar but mild, has simple and cute design thats easy to conceal, and it doesn't leave any waste, which makes it look clean. And is not heavy at all.

Flea collar

I have tried this on my dog. The side was a little big, but they're easy to cut and it did work. I didn't see no scratching or fleas on Em. Designs easy to put on and take off

Works!

[This review was collected as part of a promotion.] Fit my dog well and kept the fleas off of him. He tends to attract them at the dog park but we have been flea free for a month now. No irritation directions are easy to follow. Packaging was very high end.

Wearable protection.

[This review was collected as part of a promotion.] I was sent this product from Seresto and Influenster in exchange for my honest review. The pliable rubber collar is grey. It is easy to put on and adjust to prop size. It didn’t annoy or bother my dog . After one week, there was no skin irritation or adverse reactions. He had a bath three ddsys before application. So far no itching and no flea or tick presence appearing. As we go into spring, I’ll be watching for continued protection.

Love this collar

[This review was collected as part of a promotion.] This collar is already my dogs’ go to flea collar. It has never given any of my dogs a negative reaction, and it’s very adjustable so that it keeps the dogs comfortable. It doesn’t have a noticeable scent, and the material is like hard rubber. My favorite thing about this collar is its long lifespan; It’s good for about 8 months… very convenient for the pet owners who prefer low maintenance. All in all, I highly recommend.

Great flea/tick collar

[This review was collected as part of a promotion.] This Seresto flea/tick collar is fantastic, it works wonderfully for my 22 pound Frenchie. The size fits perfectly for her because it’s bigger & I can size it down. It has a bit of a scent but not enough to be extremely noticeable. I’d definitely recommend it!

Very helpful!

[This review was collected as part of a promotion.] This flea and tick collar can slip on a dog so easy and they ca wear with their usual collar. It’s long lasting 8 months! Instructions are very clear especially for disposing of the collar. Haven’t seen any irritation on my dogs skin. Helpful because my dog can not ingest tick medication due to a condition so nice to have other options!

Seresto

[This review was collected as part of a promotion.] We have used seresto collars in the past and loved them. Easy to put on your dog . My dogs didn’t have a reaction to this color. The only downside is they are pretty pricey.

Amazing concept

[This review was collected as part of a promotion.] I love the concept of this flea and tick collar! My dog always wears a collar so it does not bother her to wear this, she put it on and boom! Protected. My favorite thing about it is there is 8 months of pure protection - no risk of when I forget her meds that normally need to be taken or applied every other month. We went on a hike and normally there are so many ticks so I love having the peace of mind that they won’t come home on her. So far ...

Works amazing

[This review was collected as part of a promotion.] This dog collar is very durable and effective on fleas and ticks . Our dogs are outside a lot living on a farm and very active so we need something that works and this is safe and it fits perfectly and is adjustable so when our dog is a little hefty during winter months or losses weight in summer we can just adjust the color easily it works great for our pets and I’d highly recommend.

Great Long Last Collar! ♥️

[This review was collected as part of a promotion.] Absolutely amazing! I recently adopted a 7 month old shelter puppy that needed flea medicine as he had worms and vet said he needed to be on flea medicine ASAP. They suggested a product that would have cost several hundred dollars. That was when we found this product. It lasts 8 months, can get wet and kills fleas dead! I am so happy I was able to get a collar that does exactly what I needed without breaking the bank or applying medicine to his...

Effective Flea Control

[This review was collected as part of a promotion.] This flea collar worked for my 75 pound english bulldog and fit around his neck perfectly. Our dog is indoor/outdoor and this is a great preventative way to avoid a flea infestation. The scent is also tolerable!
