    The most dependable flea and tick preventative and we use this size on our bird dogs who run around in the fields and hunt and they don’t lose them even if they go swimming. Even in the summer they have not brought tick or fleas in the house that survived or were found. Dogs are very healthy. Nothing else works but this product. It it seems expensive to you then put it on affirm. It will last an entire year. We put on a fresh one each spring when we see the first big and that collar lasts an entire year. We have them on autoship twice a year to spread out the coat so they are ready to replace in the spring. And a bonus is that is that just in case one is lost or broken through horseplay which is very rare we have a backup. They don’t smell like anything either. They come with reflector clips.

    We had issues with fleas from all three of my dogs, and one of my friends had recommended these to me. I have not seen a single flea since I started using these flea collars. They are a little bit pricey, but worth every penny. My dogs have no reactions to them. They sit comfortably around their necks.

    I have a mini Australian Shepard and we live near the woods in GA. Needless to say the fleas and ticks here are a dime a dozen. I have tried the drops, the organic clips you attach to their collar, soaps, pills, etc… they ALL left him scratching away the night just as miserable as can be; he even got hot spots. My mom told me about Seresto collars. She has been using them on her cats and dogs for years. She lives in a tropical environment on the water in FL. I finally listened and wish I did years ago. I could not believe how FAST and EFFECTIVE these collars WORK and CONTINUALLY WORK!! They are made with great quality and have NO SMELLl. If you want your cat or dog to be happy, FLEA AND TICK FREE, absolutely do yourselves a favor and GET THIS COLLAR! Not kidding. This might be my 5th review I’ve ever left and I’m in my 30’s. I just had to share, in high hopes you listen and it helps your fur babies like it has my family’s. 🫶🐶🐱

    Incredible. We tried everything. These collars took care of a 2 month battle with fleas, overnight. Highly recommend.

    Very honest review here. So I have had an extreme flea infestation in my home and yard. My home was so bad my dogs preferred to be outside. I have every flea pesticide and have tried every home remedy to were at one point I had diatomaceous earth, salt and baking soda all over my house. House full of dust on everything! Saw these and simply didn’t want to pay $100 for 2 flea collars. Finally it got to the point I was bathing what looked like millions of fleas off my dogs every 3 days. Broke down and bought 2 of these collars. In 1 week my dogs slept peaceful! Didn’t hear constant scratching and walking and whining all night. I cried in relief, seriously. Well I believe I messed up when after 3 weeks I REMOVED THE COLLARS to bathe them, left them off for maybe 3 hours so my dogs could dry completely. Immediately! A couple days after, they were scratching and whining. I’m going to replace the collars in maybe a month. Next time I won’t remove them at all for bath time because I honestly believe I messed up when I removed them.

    I use this collar on one of my y dogs and it keeps the fleas off all of my dogs. This is the primary use that I buy this for; to keep the fleas away. I have used this brand for years and have never noticed any hair loss of my dog’s neck. It lasts for months and comes with a sticker to add to my calendar to know when to replace.

    I have spent so much money on flea shampoo, pills and collars. My cats were having a reaction to the bites. This collar is a saving grace. The fleas are gone- their skin is healing and fur is smooth and soft again. Definable recommend...try 1st not last.

    Best flea and tick collars ever! I bought these a little over a year ago for the first time and I love them. I did not see one flea on my dogs or in the house anywhere! The directions say they last for 8 months. I just replaced and it was over 8 months since my purchase. I noticed my dogs started scratching lately. So I ordered another couple for my dogs. Overnight- no more scratching. I have not found anything that works this well! I love not having to put a liquid substance on my dog's skin to kill fleas cuz I always feel like I'm poisoning my dogs with the liquid chemicals. I just pop open the Seresto flea collar put it on my dog, cut off the excess and I'm good to go for at least another 8 months! They're definitely worth the money! If you think about it over 8 months break that total down and it's totally worth the money. No more flea bombing the house, no more toxic liquid chemicals on my dog's skin to soak in and cause cancer! I beyond recommend this purchase for your pets!!! They will love you for it ❣️

    EXCELLENT I hardly ever write reviews for products but after using this collar for the past 5 months, this product warrants it. I was initially skeptical as my 75lb Weimaraner has a seizure disorder and flea preventatives have been known to lower seizure threshold, but after our doggy daycare got a flea infestation, we had no choice. We researched meticulously all of the available collars on the market, and despite the cost, this one seemed the best. Since we put it on him, we have not found a single creepy crawler on him. It has not caused him any rashes or hair loss, and he is an allergy baby. Highly recommend this collar to anyone searching for a durable solution to pests, especially in dogs with medical issues precluding use of oral preventatives.

    I bought l this for my Great Pyrenees mix (floofer) about one year ago after moving to a high tick area in PA. My dog has a very sensitive stomach so having a non-ingestible option is exactly what we need. I have found many ticks on her before and after putting the flea collar on her HOWEVER the ticks would latch on to her before the tick collar and now they do not latch. I will continue to buy this product.
