Our large dogs love them!
June 27, 2022
When I was asked to do a review an to comment on the collars I purchased for my dogs I knew it was going to be easy. We have been using Seresto dog collars for about 11yrs now an we haven't seen any kind of flea, or tick, not even a mosquito on our dogs! Even when our St. Bernard was a baby an rolled in the dirt, fresh cut grass, or played in the dryer leaves in the fall there wasn't any issue! Or not even wen my German shepherd/Rottweiler mixed breed jumped in our pond an our St. Bernard jumped in after them an got the collars wet we never had a problem! They are wonderful! Please buy this product for your dog they deserve it
  • The reflectors fall off an dont stay attached to the collars very long.

Best tick and flea protection and related diseases
February 16, 2022
We live in a rural area with lots of wooded and high grass areas and lots of deer with black-legged ticks. I've been using Serosto collars for years, and my dog never had a tick or flea. I chose Seresto as it kills ticks and fleas before they bite the dog, so no chance of disease transmission. Most other products make animals' blood poisonous and ticks and fleas have to bite to get poisoned and die. Biting allows the transfer of diseases. Also, I do not want poisonous chemicals in my dog's blood.

Works great

Love Seresto for my dogs. I always hated the topical treatments that left my dogs feeling greasy. Since being Seresto I have never seen any fleas or ticks on my dogs.
  • No greasy mess, put it on put the sticker on my calendar for reorder and done.
  • Nothing love this product.

Resilient Fleas Take More "Artillery"
August 17, 2021
It seems like the fleas are tougher every year, so just a flea dip won't do the job of keeping them off the pups. A good shampooing with "herbal" anti-flea shampoo and rinse with a similar dip is good to kill the buggers that are on the pups, but once they are dry, a Seresto Flea Collar will help extend the relief. Seresto collars are sturdy and the buckles don't slip so they stay the right size. They also come with fantastic little reflectors to add on so dusk-'til-dawn walks along the street are even more safe and enjoyable.
  • easy, hands-off extension of relief from fleas
  • extra reflectors from dark-time safety
  • non-slide buckles to maintain the correct size
  • not really a "con", but do check with your veterinarian to be sure your pup isn't unusually sensitive to the compound that does the anti-flea job

Protected my dogs in heavy tick infestation
May 19, 2021
Last fall I was fighting a Brown dog ticks infestation indoors. Topicals weren't working to protect my dogs at all. I was pulling dozens of ticks off them daily. Bombing the house and spraying indoors and out. As soon as the collars went on my dogs the ticks around them died. No more ticks latching on to suck their blood. The ticks went away in my house by December. So I thought! They suddenly reappeared or rose from the dead just before Easter. No doubt they went inside the walls or other hiding places to come out again in the spring. My dogs have remained tick free since Nivember when their collars went on. My 17? year old German Shepherd, Zoe passed in March so I will only be ordering two collars this time. I'm grateful that her last few months she was happy and didn't have to be drained by blood sucking parasites or have me constantly pulling ticks off her. Hoping the tick cycle will be broken soon as I am still finding hundreds of dead and live ticks looking to feed. Highly recommend this product. Nothing else worked and I didnt want to use an oral medication.
  • Works fast, no odor, highly effective in killing ticks. Very safe for use on my 3 senior dogs.
  • Tired of people saying they can cause neurological issues, etc. Since the negative article came out. I don't even listen to that nonsense. It's still annoying to hear about that.

This collar is for my 60# Black Lab. My choice for flea control for my girl has always been a Seresto collar. Entirely Pets had a great price and delivered it quickly.
  • Seresto collars last 8 month, and there is no messy monthly application.

Seresto Flea & Tick Collar f or small Dogs
December 22, 2020
I have used Seresto Flea& Tick Collars for all my dogs. They have worked very well, and I will always put a Seresto Collar on because I want my precious Pebbles protected. We have deer in our are, and other tic carrying animals. She has never had a tick in her eight years. The only thing that is hard for me, I am 73, that when I have to take it off her when she goes to be groomers, I have a very hard time pulling it apart. I finally get it out, but it is a real struggle. Other than that, I have peace she is safe and protected.

I started using the Seresto collars 2 years ago as my dog is a Lyme survivor and we live in a heavily populated flea and tick area. We've not had success with other topical treatments. With using Seresto I have found 1 dead flea and 2 dead ticks on my boy - and they were small - they did not bite him! This site gave me a great sale price and shipping rate. It arrived quickly too.

Merchant Response:Lyme is no joke. Thank you for your testimonial, Be safe Ashley
  • Easy to use, great price, no side affects, no chemical smell
  • Getting it off for bathing

Great flea protection
March 12, 2020
This is the best flea and tick protection! I used to put the liquids on my dogs necks but didn’t like the idea of the poison absorbing into their bodies. None of my dogs have had fleas or ticks while wearing this collar. And it’s waterproof too.
  • No chemicals in my dogs bodies
  • And the collar protects for 8 months. You don?t have to remember to give your pet a pill or liquid every month
  • None!

Seresto Collar is Recommended and Sold by my Vet's Office.
February 21, 2020
I have use the Seresto Collar on my 3 rescue dogs for 2 years now and not a sign of a flea or tick. I live in a heavily wooded area with deer roaming through my gardens and many other tick bearing animals. Plus, I was able to get a refund from the Seresto Company when my vet's office printed out a receipt proving I had purchased them.

One hour after putting the collar on, he stopped itching and scratching. Also, since the scratching and licking stopped, he doesn't smell, so I haven't had to bathe him but once a month.

I wish I had used Seresto collars all along!
November 2, 2019
For the first time ever, this was the first year my two Chinese Shar-Pei pups didn't bring any ticks inside with them! ... Seresto definitely is worth the price. After I put a new Seresto collar on them, I add a reminder/alarm in my iPhone for 8 months in the future and it's that simple! Their veterinarian tightened up the collars on them and reminded me that you should be able to only put 2 fingers between the collar and your pups neck ...
  • Put the collar on your pet and you're set for EIGHT months!
  • Easy to use, instructions with pictures comes with each collar.
  • Each collar comes with 3-4 reflective snap-ons for the safety of your pet in the evening. Shine a flashlight & you'll find him!
  • Reminder sticker included to put on your calendar when it?s time to change collars.
  • Happy pups = happy mum
  • It WORKS!!
  • You must follow the guidelines when fitting the collar on your pet. Routinely check the collar because it will stretch a little. May need to adjust fitting.
  • Slight chemical odor e we hen you first open the package ... but it goes away overnight.

April 25, 2019
Thought I'd try these collars even though I've had good luck with less expensive brands. About 2 weeks after putting the collars on my dogs, I was pulling ticks off both dogs. Not worth the money, they don't work as well as less expensive collars.

I have tried many flea collars before but Seresto from Bayer is the only one that I will buy,a little expensive for a little dog have to throw away over half of it wish they would come up with a way to fit a smaller dog and not pay so much for half of a collar to throw away,but love the collar will buy it again because it works the whole 8 months. Thanks!

Been using these collars for several years after switching from the poison you squirt on the dogs back. My dogs hated the liquid frontline plus and any others like it. They don't mind these collars and no more problems with ticks. I will say, do your research with these collars as there are fakes out there. They are made in Germany and come in a specific container. I've had good luck with them but I can't answer for everyone.
  • easy to use, dogs don't mind
  • price, expensive

August 22, 2018
We switched to these collars a few years ago when one of our dogs had a reaction to pills and to direct application treatments. We live in rural south Texas, so fleas and ticks are major issues. Our border collie mix, with a very heavy and thick coat, enjoys no bites and we think it's no more exoensive than buying those grocery store models that don't last nearly as long.
  • Easy to put on, stays on, works

Expensive neck ornament
April 21, 2018
I had hoped this collar would be the ideal way to control the nasty pests that plague out dogs, sorry to say it just doesn't live up to the hype in the ad campaign which motivated me to make the investment in this collar. Investment couldn't express my initial feelings prior to making the purchase,and even more so now, who would ever think you'd be spending over $50 on a flea and tick collar? Sorry I did and would never buy another Seresto collar again. Bayer can afford to spend whatever the cost to convince you this is a super product and my experience says don't throw your hard earned money away on this product!
  • Eight month protection if it worked
  • Expensive neck ornament

We have large dogs and 3 cats, they are the best Flea & Tick Collars we have ever had in 20 years. We bought only 1 last year for our indoor/outdoor cat, he never had a flea or tick. This year am buying them for all the animals!! Wish I could get a big discount!!

I live by the lake and we have plenty of deer and other furry friends come thru the yard and I have had no issues with fleas or ticks on my babies!!! My vet said he uses them on his cattle dogs and he says they help with his and they are fully outside farm dogs!!! So great product!!!!

Worst Collar Ever
September 23, 2017
This collar doesn't work! Then when you call Bayer to tell them it doesn't work, nothing but attitude. 45 minutes on the phone then they tell you- No refund! Do yourself a favor do not purchase this Flea Collar. My Vet doesn't recommend this collar. I wish I would have talked to him before I bought the collar. Junk Junk!!

Found embedded tick and had to take to Vet as it was so embedded I couldn't remove it. Tick was barely alive so collar was working to some degree. I don't like idea that collar did not repel tick altogether as we were not really in tick area and can only imagine how many my dog would have had if we were in area loaded with ticks. Looking for a different product.
