Love these collars

[This review was collected as part of a promotion.] We absolutely love using the flea and tick collar for our girl! The size large is perfect for her she is a standard sized golden doodle. She has longhair and whenever noticed any side effects and it’s super easy for her to wear and have that coverage without having to remember to do a chew or serum every so often. Easy to have her covered!

My pups needed this! Works well!

[This review was collected as part of a promotion.] This flea collar really worked for my blue healer, I pick at my dogs everyday for fleas since our yard is filled with them and since I put on the collar I haven’t found as much! I think the instructions were clear and jr helped me kill all the fleas on my baby pup! I put the collar on and it really helped deflect fleas! Happy customer

Wonderful way to protect from fleas and ticks

We really love Seresto collars! They repel fleas and ticks, keeping them off my fur babies! Love that I don’t have to take them off for bathing either.

Nice

[This review was collected as part of a promotion.] Took my little human camping recently and this thing was a lifesaver. Did it's Job by keeping the ticks away and my girl didn't seem to mind it at all.

Great collar for your furry friend.

[This review was collected as part of a promotion.] My dog is important to me. Saresto and Influenster sent me this collar to try out. The size was great and my dog wasn't able to shake it off. I have seen no fleas or ticks on him. We love next to a field with cows so it's important to keep him safe from pesky critters. Thank you Influenster and Saresto.

Very effective flea collar

[This review was collected as part of a promotion.] Protect your fur babies from biting fleas and infestations. This flea color was easy to apply to my energetic frenchie and did not irritate his skin at all. Ive never been a fan of the smell from this product, but I can only assume the smell helps with the effectiveness of the product. My active boy was unbothered by the collar and the collar seemed to be effective since I have yet to find any creepy crawlers. I will continue to use this produc...

Great Product

[This review was collected as part of a promotion.] We love the convenience of these collars. To be able to put them on and forget about the for most of the year is great. They work well to keep the fleas and ticks off the dogs too, especially during camping season in the woods. If I had any complaints about these collars though, I would say that, despite not cutting any length off of ours, the end seems to wiggle free of the loops every so often and require adjustments.

Good product, just not for my dogs

[This review was collected as part of a promotion.] There is nothing wrong with the product itself. It is effective for repelling fleas and ticks. It’s just not the product for my dogs. I prefer something they don’t need to wear 24/7–especially since one goes to daycare can cannot have a collar on.

Flea collar

[This review was collected as part of a promotion.] I have never tried a flea and tic collar on my animals till now. Where we live it is starting warm up and flea season is starting. So far so good. Have not noticed and fleas on our dog. Our dog has only been wearing for a few weeks.

Easy to use

[This review was collected as part of a promotion.] This dog collar is very easy to put on and the material is soft. It does not irritate my dog at all. So far, it’s been effective, though we barely started better weather where he will be outdoors.

Great value and easy fit

[This review was collected as part of a promotion.] This product has a versatile fit; I thought it wouldn’t be big enough for my dog but it has an adjustable length. My dog didn’t mind it while he had it on, so it was easy to have on and not worry about catching fleas and ticks. I didn’t notice anything on him, but it’s also a little cooler now so we’ll see the true effectiveness when summer hits.
