Choosing the right size for your Seresto dog collar
You choose the size of your dog's Seresto collar according to its weight, in order to respect the dosage which is calculated per kilo. We commonly use the name “small dog” or “large dog” collar, but it is the weight that you must be interested in before the size.
A small, stocky dog (bulldog or Welsh corgi cardigan style) may need a Seresto 'big dog' collar, while a larger but wasp-waisted dog (whippet style) will need to use the Seresto 'small dog' range. .

The cat version of the Seresto collar
The cat version of the Seresto collar is only available in one size: 38 centimeters long. It contains the same active ingredients as the dog version, but at different dosages. It is intended for all cats, from the age of 10 weeks.
Properly position the Seresto collar
Adjust the Seresto collar so that you can easily fit 2 fingers between it and your dog's or cat's neck. If necessary, cut the superfluous part to prevent it from hanging in the void.
Once the collar is positioned, make a movement against the hair so that it comes into contact with the animal's skin to better distribute the pest control product over the entire body.
Its anti-flea and anti-tick action
The Seresto collar contains two active substances — imidacloprid and flumethrin — which act on the nerve cells of the parasites. Their synergy is equivalent to a veterinary drug that operates on a broad spectrum including ticks, fleas and biting lice, whether their favorite prey is a cat, a small dog or a large dog.
Regardless of the stage of evolution of the parasite
The Seresto collar affects ticks and fleas, whatever their stage of development. It prevents the development of larvae because it kills flea and tick larvae. It also eradicates adult fleas and ticks.
Long-lasting, preventive and curative
The treatment spreads gradually over 8 months. At the end of this period, the collar should be discarded and replaced. It acts in prevention, by dissuading the parasites from coming on the animal, but also attacks those which would have nevertheless settled in its coat by killing them.
