How does it work?

At first sight, Seresto might look like just another flea collar, but there’s a lot going on beneath the surface. The collar consists of a polymer matrix that slowly releases two active ingredients – imidacloprid and flumethrin – onto the layers of your dog’s skin and coat. The collar works to build up an invisible layer of protection that kills fleas and repels and kills ticks that come into contact with your dog.

How to apply

Remove the collar from the pouch.

Remove any remaining plastic connectors on the inside of the collar.

Put the collar around your dog’s neck and insert the loose end into the 2 loops

Make sure it's neither too tight nor too loose. Ideally two fingers fit, laid flat between the collar and your dog’s neck.

Cut off any extra length of collar, leaving about 2 cm of the loose end beyond the second loop.

FAQ

What is Seresto?

Seresto is an innovative collar that protects your dog from ticks and fleas for eight months. This means that you don’t have to worry about more frequent applications of flea and tick treatments, and there is no risk of forgetting to do so.

What makes Seresto different from other flea and tick collars?

Innovative technology enables the collar to release low, safe doses of its active ingredients over long periods of time. These are transferred to your dog’s skin and coat, and spread across their entire body to keep them protected from ticks and fleas for 8 months.

What are the active ingredients in Seresto?

There are two: imidacloprid, which kills adult fleas and flea larvae; and flumethrin, which repels and kills all life stages of ticks. Both ingredients act on contact without the need to bite.

Why am I still seeing a flea on my dog when they're wearing a Seresto collar?

Fleas may still jump onto your dog when they go past them, even they're wearing a Seresto collar. The active ingredients work on contact, which means the fleas need to grab onto the hair to get exposed to the active ingredient. However, once they have jumped on, the fleas will become disorientated before dying and falling off. You may therefore sometimes also see some fleas moving slowly or ticks tangled in your dog's hair.

My dog has started chewing the collar, should I be worried?

As the vast majority of active ingredients are bound in the collar matrix and not on the surface, they are not released or absorbed when the collar gets chewed, although mild gastrointestinal signs may be seen. Nevertheless, you should avoid chewing, and if your dog manages to get their own collar into their mouth it’s likely that it is applied too loosely. Ideally two fingers fit, laid flat between the collar and your dog’s neck.

Is Seresto safe for puppies?

It’s safe for use on puppies aged 7 weeks and older.

Should I leave a gap between taking off an old collar and putting on a new one?

No. It's important to put it on without any delay to assure a continuous protection of your dog.

My Seresto collar doesn’t smell at all. Does this mean it’s not working properly?

Not at all. Seresto is odourless, which means you don't have to put up with any of the unpleasant smells you usually associate with older flea and tick collars.

Other flea and tick collars require stretching to activate them. Do I have to do this for Seresto?

No. Stretching the collar for activation is not necessary. Once applied, the active ingredients in Seresto are quickly distributed throughout the entire body surface to protect your pet.

Can the Seresto collar be used alongside normal collars?

Absolutely. Seresto can be worn alongside your dog’s usual collar without losing efficacy, as long as the Seresto collar is in contact with hair and skin.

My dog is scratching at the collar, causing redness and irritation. What should I do?

If your dog isn’t used to wearing a collar, there is a chance that they might develop mild reactions such as scratching, redness and hair loss. These symptoms usually disappear within one to two weeks, without removing the collar, as your dog gets used to wearing it. In some cases, temporary collar removal may be recommended until the symptoms have disappeared. In rare cases in dogs, application site reactions such as dermatitis, inflammation, eczema or lesions may occur and in these instances, collar removal is recommended. Please consult your vet if the symptoms persist or become more severe.

What should I do if the collar gets dirty? Will a muddy collar still keep my dog protected from fleas and ticks?

We are not aware of mud having an impact on the release of the active ingredients in Seresto and hence its efficacy. If the collar does get dirty, you can simply wipe it down with a moist cloth.

Can I attach a leash or a nametag to my Seresto collar?

Seresto has not been specifically tested with such items, so we do not recommend attaching accessories to your dog’s Seresto collar, especially if such accessories cover the collar’s surface.

Is Seresto dog collar water-resistant? Do I need to remove the collar if my dog gets wet?

Seresto does not need to be removed when a dog gets wet or is bathed. The active ingredients are contained in the collar matrix and will not be released into water. They spread through the lipid layer of the dog's skin and hair and even if this lipid layer is partially washed off by bathing, Seresto will quickly replenish the active ingredients and the pet will be protected again. 

However, prolonged and intense exposure to water or extensive shampooing should be avoided as the duration of activity may be reduced.

How often can I let my dog swim when using a Seresto Collar?

Seresto is water-resistant. It remains effective following swimming, the use of a mild shampoo with non-detergent ingredients, or exposure to rain or sunlight. There is no need to remove the collar for swimming. Under normal conditions, i.e. less than one bath per month, it's effective for 8 months; for dogs that swim or bathe frequently, the duration of activity may be reduced.

What happens if my dog gets its collar stuck on something?

Seresto is designed with a double safety-release mechanism. In the unlikely event of your dog being trapped, the collar will widen when they give it a hard pull, allowing for a quick release. The small dog collar has a two step safety mechanism as it is additionally equipped with a predetermined breaking point, so a harder pull will break it.

How often should I check the fit of the Seresto® collar on a growing puppy?

Puppies grow at different rates and we recommend frequent checks of the collar and readjustment if necessary. 

How should I dispose of a Seresto dog collar?

Used collars or any remnants should be wrapped in paper and placed in garbage. The product should not enter water courses.

Why does Seresto have a white powder on the surface, when taken from the pouch?

The white powder is caused by stearic acid, a release agent used in the production process to make it easier to release the collar from its mold. 

Stearic acid is completely safe and also graded for use in certain foods. The white powder normally disappears within a few days after application of the collar to your animal but if you prefer, you can simply wipe it off with a cloth.
