About Fleas and Ticks
Fleas and ticks are more than just annoying. They can cause several health issues.
Fleas
A single flea can feed on your pet for over 3 hours.
Fleas can also lead to potentially serious health risks:
Fleas are not just a “dog problem”
You or your dog can bring fleas home to infest your cat without you realizing it. This, plus any outside exposure can put a cat at risk for fleas.
Ticks
Repelling and killing ticks is important:
The mouth parts of a tick act like a tiny harpoon, ready to anchor into the dog or cat's skin. After they are attached and are feeding a number of organisms can enter a dog or cat's bloodstream. If a tick is repelled or killed, it cannot attach and transmit organisms that may cause disease.
Ticks may also carry organisms that can cause:
How Seresto works
An effective combination
Inside the unique polymer matrix of Seresto are two active ingredients:
Sustained release technology
Seresto works similarly to a monthly topical, but as the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. The active ingredients spread from the site of direct contact over the skin surface.
Bayer's polymer matrix technology is designed to slowly and continuously release the active ingredients over eight months, a duration that makes it clearly different from other collars.
Seresto is water resistant
The active ingredients of Seresto are contained within the Bayer Polymer Matrix, making it water-resistant. Therefore it is unnecessary to remove the collar before the pet is immersed in water. Seresto remains effective following a shampoo treatment, swimming, or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for eight 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 five months.
How to Apply
Monthly flea and tick treatments can be time-consuming to apply. Plus, remembering to apply them monthly can be a hassle. Seresto takes just minutes to adjust on your dog or cat, and provides treatment that lasts eight months against fleas and ticks.
Application is easy
Make sure Seresto fits securely
As a guide, it should be possible to insert two fingers between the collar and the neck. Make sure the collar is not loose enough for the cat to put its leg through.
If your dog or cat is not used to collars
Please carefully observe your dog or cat when it’s wearing a collar for the first few days, especially when the pet is not used to wearing a collar. Try using a tasty treat, toy or other activities to distract your dog or cat’s attention from the new collar. Occasionally slight itching may be observed in animals that are not used to wearing collars in the first few days of fitting. Ensure that the collar is not fitted too tightly.
Safety-Release Mechanism
Because some pet owners may be concerned that a cat or small dog could get stuck while wearing a collar, Seresto is designed with a safety release mechanism. In the unlikely event of the cat being trapped, the cat's own strength is sufficient to widen the collar to allow for quick release.
A hard pull causes the ratchet-release mechanism to allow a widening of the collar.
The small dog and cat collars are equipped with a predetermined breaking point. A harder pull triggers the breaking of the collar at this point.
If your cat is not used to collars
If the collar feels foreign, the cat especially may scratch at it initially but should adapt in time. Offering a treat or toy after applying Seresto may be enough of a distraction to end this behavior.
Slight hair loss and mild skin reactions due to the mechanical irritation of the collar may occur at the application site, which usually recover within a week or two without the need for collar removal.
Note: Please see Product Label for important Precautionary Statements and proper Storage and Disposal.

I have two dogs and three cats and always had a problem with fleas, especially during the summer months. These flea and tick collars are amazing. Doesn't seem to matter where they wonder, all of my pets have been flea-less since using. And it does last for at least 8 months. Best flea prevention I have ever purchased.

Seresto Dog Flea and Tick Collar contains the same percentage of active in the sizes, you would just choose the size that best fits your pets neck. It would not harm your small dog if you use the larger collar. You would just have to cut more off to fit down to size.
