Truly unique technology for your dog

Seresto® is a unique polymer matrix collar that offers a continuous supply of two active ingredients: imidacloprid and flumethrin for effective 8-month protection against fleas and ticks. That's one convenient, non-greasy, odorless flea and tick collar instead of 8 monthly treatments.

The active ingredients are stored within the collar. They are released in low concentrations and are distributed over your dog's hair and skin surface for 8 months. As active ingredients wear off over time, Seresto® for dogs continuously replenishes the skin and coat with a new supply of active ingredients. Fleas and ticks are killed through contact with the active ingredients — no biting required.

Questions (61)
I have a 105lb Newfoundland, will the seresto collar fit?
It is 27.5 inches (70cm), so it should be ok.
one of my dogs is 105 lbs and another one is 20 lbs...do I get the large for both or small for the little one???
Both of your pups will need the large collar. The Seresto small dogs collar is only suitable for dogs under 18 lbs.
Have a Rottweiler 125# with a neck size of 25” maybe 251/5 will a large Seresto collar fit
Yes. Seresto Large is 27.5 inches wide and is adjustable.
Is it ok to take it off for baths and swimming and then put it back on? I know you say you don't need to but I was wondering if it is ok.
Yes, you can take it off for baths and swimming if you want to.
I have a German Shepherd Ridgeback mix who weighs almost 90lbs with a lot of skin around his actual neck, will this fit him? Thanks!
The large collar is 27.5" (70 cm.). It should fit your dog without a problem.

This is the best thing on the market. Had flea problems all last summer, even tried the supposedly the best topical product, still had fleas. Got this, put it on my dog, like magic NO Fleas. Thank you for this amazing product.

We had a flea infestation that was so bad you could see them jumping from the grass on to the dogs. They looked like flying specks of black pepper. We tried everything. We couldn't eliminate them and we couldn't keep the dogs flea free. Finally, out of desperation, I bit the bullet and purchased two. We have been flea free for four years. I make sure to have the new ones ready for the next year.
