Happy & Safe Dogs!

We rely on Seresto Flea and Tick collars for our two dogs! For 12 years Storm (our Lab mix) has been able to run free on our 100+ acre farm. We continue to use Seresto for our German Shepherd puppy who is not quite a year old yet! Both dogs are dark and looking for ticks on them is really difficult so trusting Seresto to not cause issues with digestion, breathing or skin issues is huge for us! Our pups are able to stay healthy and enjoy their farm adventures!

Works but be cautious

[This review was collected as part of a promotion.] This flea collar does exactly what it’s supposed to do , keeps fleas off your dog! Buttttttt you have to very careful because some dogs may have sensitive skin and have bad reactions to the collar ! You do have to keep the collar dry to preserve whatever is actively working to keep the fleas away. Collar is really long so you can cut and adjust it to your dogs fit. It worked great for us 👌🏼

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 com...

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 t...

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 i...

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.

Really works to keep fleas and ticks away!

[This review was collected as part of a promotion.] My dog is a mini schnauzer but they still recommend the large dog for her because she’s a little chubby. It’s the best way to keep fleas and ticks off her in the summer when we go for hikes. Once she got fleas from the groomer and the only thing that killed them off was this collar. Now I just use it in the summer months to keep her tick free. The collar can be cut to fit and it never seems to bother her.

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

Great Protection

[This review was collected as part of a promotion.] So far so good! There was no odor on this, it was easy to put on him and now he's protected for up to 8 months! Our Winter was so weak and that means lots of bugs this Spring - so glad my dog will be protected from ticks, fleas and lice. I'm pretty sure it's comfortable because my picky dog hasn't scratched at it at all. Very happy.

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!
