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 itching, 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 repeated 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 up to 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?
Both the small and large Seresto dog collars feature a ratchet release safety mechanism. So 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 another 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 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.
