8 Months of Stress-Free Flea and Tick Protection
[This review was collected as part of a promotion.] The Seresto flea and tick collar is an absolute lifesaver! It provides up to 8 months of continuous flea and tick protection, which means no more stressful and messy monthly topical treatments or missed doses. The leave of mind it provides is truly priceless. Knowing my pups are protected around the clock without any extra effort is incredible. It’s so easy to use, just put it on and forget about it. The collar is odorless, adjustable, and comes with little reflective clips that you add to it so that you can even see it at night when light hits it. My pups don’t even notice that it’s there, and there’s no greasy residue or chemical smell to worry about. Its small profile means it won’t interfere with their daily activities, and the fact that it’s water resistant means that it’ll hold up through backyard activities and outdoor adventures without missing a beat. I do take it off during their baths just to be safe that it doesn’t lose its function from constant water exposure. For the level of protection it provides, the value is unbeatable. Flea and ti k prevention can feel overwhelming, it the Seresto collar makes it completely stress free. Once you try it, you’ll never go back to any other method.

Effective!
[This review was collected as part of a promotion.] I used this collar on our family dog to protect him from fleas. So far we have seen no evidence of fleas and he seems to tolerate the collar well! I would purchase again the the future.

Great for active dogs
[This review was collected as part of a promotion.] This collar is quite durable. My dog is a beast. Lots of throws and plays all day, constant running, and daily walks. We have a very active dog, and the collar stayed in place. It’s odorless and worked quite well for my dog.

Easy to put on, no smell
[This review was collected as part of a promotion.] The Seresto dog collar fits our long haired German Shepherd puppy’s neck with no issues. It was easy to put on and so far it hasn’t loosened when he scratches his neck. I worried about that happening since it has more of a sliding buckle than a prong or tab to keep it in place. The collar doesn’t have a smell and doesn’t seem to irritate him any. iIt’s said to be vet-recommended and last up to 8 months so only time will tell if it’s worth the price tag.

Perfect Flea and Tick Repellent
[This review was collected as part of a promotion.] I love this collar as a flea and tick repellent! It’s so easy to use and lasts a while! It’s not oily and greasy like other products! They last all season too with no issue! Fits fine, you just cut off the extra!

Durable and effective!
[This review was collected as part of a promotion.] Love that it is lightweight and easy to put on. It doesn’t have an odor and works well on my dog with a double coat! He’s a rough and tumble dog and it has held up well to his rough playing!

Great for suspicious pets
[This review was collected as part of a promotion.] This is my go to collar for months of flea and tick prevention. I don’t have to remember monthly meds for dogs who are suspicious of anything in the shape of a pill!

Highly effective
This is very long lasting and effective protection for dogs. I currently use it and plan to use this collar for as long as they’re available! There’s been no scent or remaining oils left from the collar either which is great.

Reliable and easy!
[This review was collected as part of a promotion.] 8 months on protection for my best girl! We live in Tennessee, fleas and ticks are rampant all year long. Monthly prevention works well, but it’s a lot to keep up with on the farm. I can put this collar on my fur kiddos and not have to worry for 8 months! Not to mention, 8 months of this collar protection is so much cheaper compared to monthly prevention! I love seresto!

Great Extra Protection!
[This review was collected as part of a promotion.] I love Seresto collars! Murph and I like to go on plenty of hikes throughout the year, and those often include areas that are loaded with ticks. He's on a chewable flea/tick/heartworm preventative year-round, but I like to use Seresto for the warmer months in addition to that for the added protection. The repellant effect of the collar is a huge help in keeping these pests off Murph! I would wear one myself if I could! The long lifespan of it is a huge help, and I'm confident in the effectiveness of it after delving into the research done on them. I wouldn't recommend any other flea collar--Seresto or bust!

A comfortable, long-lasting collar that effectivel
The Seresto Large Dog Flea and Tick Collar has been fantastic for keeping my bigger pup protected. It’s easy to adjust and fits comfortably without bothering him, and it provides months of continuous flea and tick prevention. I’ve noticed a huge drop in pests since using it, and it’s so much easier than monthly treatments. Reliable, effective, and stress-free—highly recommend for any large dog.

Not for my dog…
[This review was collected as part of a promotion.] The product packaging arrived very damaged. The collar was not affected but I just don’t see myself replacing a vet recommended, edible , multi-use prevention with this method. The collar fit but is not cute and for me gives the perception of a dog owner that doesn’t invest in their pets to the best care available. I do realize it may be a affordable solution for some but I don’t think it is for me

Flea protection
[This review was collected as part of a promotion.] Thank you Influenster and Seresto for sending me this product free of charge in exchange for my honest opinion. Seresto Large Dog Collar for Dog over 18lbs comes in a 1 pack. It is for 8 months prevention and treatment of ticks, fleas, and flies for dogs. Can also be used for puppies 7 weeks and older weighing more than 18lbs. Long lasting protection. Comfortable for the dog. It also has soft ridges inside to keep air flow but very secured on the dogs neck without causing irritation.

Perfect for my dog! As always!
[This review was collected as part of a promotion.] I’ve always had good things to say about Seresto collars. They do a great job of keeping the fleas and most importantly the ticks off my dog. They never cause irritation and they are easy to fit and put on. I like how they aren’t too bulky so he can wear his main collar without it seeming like he has too much on around his neck. No stinky smell. Great product!

Skin irritation
[This review was collected as part of a promotion.] The colllar was easy to put on, I have a large lab who is very sensitive to stuff so this did cause some irritation so we only used it for a few days and then disregarded it.

A little added protection never hurts
[This review was collected as part of a promotion.] Our big girl doesn’t mind wearing her Seresto Collar at all. The Large size fits her perfectly. With her going in and out all day, the added protection puts my mind at ease that the fleas will stay off our girl. This collar doesn’t seem to bother her like others have either . She doesn’t scratch at it at all, which is great!

Great Flea and Tick Prevention.
[This review was collected as part of a promotion.] This size large flea and tick collar fit my 100+ pound Rottweiler, Zeus, perfectly. It did not have a super strong odor like some other brands I have used in the past. It seems to be very durable. It was easy to assemble and put on him and has stayed on securely. The instructions were straight forward and easy to understand. Since it has only been on him a couple of days I can’t speak on how effective it is and keeping away the ticks but am hoping it works great as I loved everything else about it!
