One collar per animal to be fastened around the neck. For puppies and kittens, allow additional length for growth.

Step 1: Remove collar from protective bag directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar
Step 2: Insert end of the collar through the buckle. Adjust the collar around the animal’s neck without tightening it too tight
Step 3: As a guide, it should be possible to insert 2 fingers between the collar and the neck
Step 4: Pull excess collar through the loop(s) and cut off any excess length extending one inch (2 cm) beyond the loop(s)
Step 5: Seresto comes with optional reflector clips that can be attached to the collar for added visibility at night. Simply attach the reflector clips by evenly distributing them on the non-overlapping part of the collar

Safety-release mechanism: A medium tug will widen the collar. In the unlikely event of a pet being trapped, the dog or cat’s own strength is sufficient to widen the collar to allow for quick release. The cat and small dog collars are equipped with a predetermined breaking point. A harder tug can break the collar at this point.

Finally something that works! My dog is allergic to fleas and the topicals stopped working. She had a really bad reaction to comfortis so that was not an option nor do I want my dogs digesting chemicals so I tried this collar and it works great! I took it off recently and forgot to put it back on and my dogs got fleas right away. I didn't realize how good it was working until I took it off. August 24, 2013
Initial Impressions Our flea season is just now kicking up so we will see how it performs and I will leave an update here in a month or two. But my initial impression of this product is that is a quality build and seems to be well thought out. I like the feel and the fact that this thing, right out of the plastic, has literally no off-putting smell at all. I love the reflectors to help with the visibility of my dogs (I have active hunting dogs). My Vet said that last year the Serestro Collars and Comfortis were the only two things that customers said worked against the flea horde that had invaded our homes. I surely hope they were right. (to give a little background: Last year in Middle Tennessee the flea and tick populations were of epic proportions. At my house alone we went from a somewhat heavy year to complete infestation in a matter of about 2 weeks. We had religiously used a Frontline and Advantix rotation for several years that worked great….and then it just stopped for everyone I knew.) Even if the collars fall through I am hooked on’s customer service and professionalism. I have not had the pleasure of having a good customer service experience in some time. That makes my experience with all the more enjoyable. Great people and I will be coming back for my dog’s and cat’s needs. March 11, 2014
Great Product for Fleas & Ticks I am so happy to have found these collars. We are situated on five acres of pine forest in southwest Georgia. Fleas and ticks are as common as deer and timber rattlesnakes. I have tried the oral flea medications which in turn made my girls extremely sick. I have always used tick collars that were purchased from the vet every three months. They always worked, but were only for ticks. I didn't like the oily stuff you apply on their backs and the powder stuff seemed to leave such a build-up on their skin and hair. These collars are great! The collar is very sturdy and the little reflectors are an added bonus. Collars fit exceptionally well on my 40 lb and 94 lb dogs. Also, I was very impressed with the packaging. Very ingenious!

Great product - great price I have ordered the Seresto collars before but this was the best price and I received them quickly! I will continue to do business with Chewy! :) March 29, 2014
My Dog had a bad reaction to this collar. My dog had a bad reaction to wearing this collar. I recommend you watch your dog and make sure your dog is fine with it. I had to take it off after 10 days. Thankfully he recovered. March 30, 2014
Excellent product if it stays on I switched my dogs to this collar from frontline. Ticks are a common concern for us because of the time my dogs spend in fields and woods. I've seen a dramatic decrease in the number of ticks found on them since they have been wearing it. And the only one I found was dead so that's good. My only complaint was one of the collars kept falling off and it eventually became lost. It's an expensive collar to be lost. Replacement collar has had no issues - so perhaps I just got a rare defective one. I'd still recommend using the collar but suggest that if you notice it coming off easily, you call the manufacturer about a replacement before it's lost. September 13, 2014
excellent flea control product I own and operate a grooming shop and some of my clients have been using these collars for several years. I find NO fleas on their dogs(which previously had fleas). Plus I have found dead ticks (that never attached) on dogs that wear seresto collars. To me, that speaks for itself and is better protection against lymes disease than any of the spot -on products on the market. And believe me, I've seen them all and tried most of them on my own pets over the years. I'm switching all six of my dogs to seresto collars and recommend them to all of my clients August 5, 2014
Been waiting for this level of tick control for years! We had both of our boys on Advantix for over 6 years and then all of a sudden they started coming in with ticks attached and feeding. These collars last longer, are less intrusive than a topical solution and use a chemical until recently only avaible in Europe. They REALLY work!!!!!!!! February 28, 2014
