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 hop...

Easy to use

[This review was collected as part of a promotion.] I used this on my husky and it was easy to put on her. Didn't seem to bother her neck. In terms of being effective I would say it works as no fleas and ticks on her. The scent is a little overbearing and I wish it was lighter. But it didn't seem to bother her.

Worth a try

[This review was collected as part of a promotion.] Easy to apply. It fits my golden retriever easily. Easy to adjust. I hope it works as it is intended to. Supposed to last 8 months which is substantial. Only supposed to bathe your dog once a month with this on.

Good so far

[This review was collected as part of a promotion.] I did receive this product for free from Influenster to review. I kinda hesitated to give this a perfect five-star because I feel like i haven't had enough time to fully test its flea and tick repellent claims. But i did give it five stars because i've had no issues with it so far, and I only have a limited time to get my review in. As far as instructions, there is a booklet in the container that clearly explains how to put the collar on and ev...

Happy with your collar for my dog

[This review was collected as part of a promotion.] This is going to be perfect for summer time my dog plays outside and this will keep him flea/tick free. Claims to last up to 8 months protecting. It is a perfect fit and I like that this doesn't put my dog at risk of getting side effects which some chewables do.

Budget friendly and no side effects from our fur b

[This review was collected as part of a promotion.] This is a light weight collar that fits my 80lb lab/husky with plenty of room to cut off the excess. She is wearing it comfortably and it stays in place very well. She has been wearing it with no side effects or discomfort. Great value in comparison to other brands we have tried.

Great product

[This review was collected as part of a promotion.] Easy to apply and effective for longer than most flea and tick products. These fit well for large dogs and comes in a safe aluminum container. I would recommend these for use on your dogs.

Wonderful lasting protection

[This review was collected as part of a promotion.] We have used semester collars on our 5 year old American bully for the last 3 years. They work great and keep bugs off for a long time without having to worry about buying flea medicine every couple months. We will continue to use these on him ans any other dohs we may have in the future. Reliable and long lasting protection.

Effective and easy use

[This review was collected as part of a promotion.] This collar was easy to apply to my dog and did not need instructions. My dog didn’t seem to mind the collar and adapted well to it. I feel like it was effective and I like that it’s a neutral color. I would recommend this to friends.

Best flea and tick collar for large dogs on the ma

[This review was collected as part of a promotion.] Our dog is very picky when it comes to flea and tick collars! He cannot get this one off and he does not itch around his neck with it on! It’s the first collar we found that he doesn’t do this

Easy to use puppy protection!

[This review was collected as part of a promotion.] I think this would be a great product for an outdoorsy family. My dog doesn’t get much activity in areas where we have to be concerned about fleas and ticks so making him wear a collar for eight months straight is a bit excessive. It does seem to be really great coverage for fleas and ticks. It is easy to apply and I like that it can be altered to fit should a dog change sizes. The instructions are easily follow. If I were going on a vacation w...

No prescription needed

[This review was collected as part of a promotion.] [Incentivized] Peace of mind knowing this collar will keep our dog safe for up to 8 months. Enough time to keep her safe throughout the warmer season and at an affordable price. It will last less if she gets in the pool but all we do is remove it while she's in the water. It protects our furry baby from fleas, ticks, lice and flea larvae. It came in just in time because the days are getting warmer and it's usually when we notice fleas or ticks....
