Description

Give your dog long-lasting protection against fleas and ticks with the number- one vet-recommended flea and tick collar. Unlike other flea and tick protection, Seresto small dog collars kill and repel fleas and ticks for 8 continuous months. Seresto collars make your dog’s comfort a priority by killing fleas and ticks through contact, so pests don't have to bite your dog to die. Existing fleas die after 24 hours of initial application of the collar. After 24 hours, any new fleas on the dog are killed within 2 hours with protection against further flea infestation lasting 8 months. The prevention of infestations with new ticks starts at 48 hours after application of the collar. 48 hours after application, any new ticks are repelled and/or killed in as quickly as 6 hours. Seresto small dog collars protect against common pests like deer ticks, American dog ticks, brown dog ticks, and Lone Star ticks; they're also effective against chewing lice for 8 months. Fleas and ticks not only cause discomfort; fleas can transmit bartonellosis or tapeworms. Ticks can transmit Borrelia burgdorferi, which causes Lyme Disease. Check the product label for information on potential side effects. Seresto small dog flea and tick collars are for dogs at least 7 weeks old and up to 18 pounds, and no prescription is needed. They're odorless, non-greasy and water- resistant to swimming, exposure to rain or sunlight, bathing, and shampoo treatment. Seresto is a trademark of Elanco or its affiliates. Seresto small dog is water resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. In order to maintain an 8-month duration, dogs must not be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to 5 months for flea control and reduced to 7 months for tick control.

    • Recommended by vet. Haven't had fleas or ticks on dogs in years.
These were recommended by our vet. We get them in March and they last all flea and tick season. We have used these for years on our dogs and have never seen a flea or tick on them. They may be a little more expensive than others but the are worth every bit

    • The solution we wish would have found years ago!
For anyone out there that feels like they have tried everything to get rid of fleas, try this collar! We've had it on our shih Tzu for several months now and are finally flea free! Thank God! Over the course of several years we've tried so many options.. different shampoos, "all natural" flea collars, essential oils, flea lamps, topical flea medicine on the back of the neck, nitenpryam/ lufernon powder or tablets you name it.. nothing has worked as well as these collars. It was nonstop scratching, hair loss. Now after several months, my pup's hair has grown back and he doesn't scratch or bite at himself anymore! It's been such a relief. I was worried about the collar essentially being a pesticide, but I have not noticed any negative side effects on my pup. No skin irritation or anything. The collar will take some time to work. If you have multiple animals you must get them all collars. It is recommended you also vacuum any carpets, at least periodically. Within a month or two, there should be a noticeable difference. ... show more

    • Works amazingly well
A game changer. My dogs went from infested to flea free. My dogs are elderly and I was worried about anything oral and the shampoos just weren’t cutting it. With these collars the fleas were gone in 24 hrs. Quite amazing actually. Oh and I’m a huge cuddler, I can still get up close and it’s not greasy or medicine smelly. Highly HIGHLY recommended ... show more

    • Miraculous flea collar
I have a chihuahua and a dachshund.Over the years I have tried every single thing to get rid of their fleas. I was always saying "I'm not spending a bunch of money on a flea collar" talking about Seresto. I finally gave in and got the 2 pack for them. I swear, immediately they both stopped scratching and itching and we were all able to get a full nights sleep without them waking us up by wiggling around so much due to the fleas. It is a miracle !!! I am so so happy that I bought these and will never not have one on my dogs. When I saw how great they worked, I bought 2 more for my grandsons 2 dogs. Now everyone is happy. Thank you so much for making our lives flea free !!!! ... show more

    • Very effective
We have used these for years. I have never found a flea on any of my dogs. There has been about two ticks in over 10 years. We live in a very tick prone area, so that doesn't surprise me.

    • it's a scam! Do not buy these from Amazon!!! Buyer beware
Seresto collars work fine when bought from a vet. But we have tried multiple times to purchase these from Amazon and they are just useless plastic. they do not prevent fleas at all, in any way! Amazon will do nothing about it either. Complese waste of money and a horrible scam.
