We source all our products from manufacturer approved distributors or directly from the manufacturers. Chewy takes pride in ensuring that our furry friends’ wellbeing is always our top priority. We have worked hard to partner with all of the manufactures to deliver 100% authentic products

The Seresto® collar works with a unique polymer matrix of two active ingredients, which spread from the site of direct contact over the skin surface of your dog:

Imidacloprid has been used in products for years to control flea infestations.

Flumethrin effectively kills and repels ticks.

Flumethrin works together with imidacloprid to provide dual action against fleas and ticks. No other product has this combination of ingredients.

Sustained release technology  

Seresto® works similarly to a monthly topical in the fact that the active ingredients spread from the site of direct contact over the skin surface. The active ingredients in Seresto® are released from within the collar and, thanks to your pet's skin and coat, spread from head to toes, even the tail. As the active ingredients wear off over time, a new supply is continuously replenished for 8 months. The long-lasting, 8-month duration of Seresto® differentiates it from other flea and tick collars. 

How to apply the Seresto® collar on your dog:

1. Remove the collar from its packaging. 
2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain. 
3. Insert the end of the collar through the buckle. 
4. Adjust the collar around the dog’s neck without tightening it too tight or leaving it too loose. 
5. As a guide, fit two fingers comfortably between the collar and the neck. Pull excess collar through the loop(s). Cut collar to a length no greater than one inch (2 cm) beyond the loop(s) unless it is on a growing puppy, where some additional length may be needed for adjustment as the animal grows. 

Seresto® kills fleas and ticks.

Seresto® was designed with specific ingredients at doses that are active against fleas and ticks. Studies show that fleas and ticks are highly susceptible to the combination of imidacloprid and flumethrin found in Seresto®.

The continuous distribution technology ensures that both active ingredients are slowly and continuously released from the collar toward the animal. This ensures that concentrations of both active ingredients are present on the dog during the entire protection period. The active ingredients spread from the site of direct contact over the skin surface. 

It’s crucial that pet owners purchase real and genuine Seresto® products from authorized veterinary clinics and trusted retailers to help ensure product authenticity and performance.  

Fleas are very hardy pests that are quite capable of hitching rides on a variety of mammals. Wild animals or feral pets traveling through the environment may be a source for a pet’s exposure.Fleas may be brought to the house by: * You – attached to clothing, luggage, dog blankets, etc. * Your pet – any time your pet steps outside your house, they are potentially exposed to fleas, especially in areas where there are other animals. * Stray or homeless cats and dogs – since these animals are not being cared for, they are easy targets for fleas. A single feral cat walking through your backyard even just one time may drop many flea eggs into the grass or under shrubs. * Wildlife – particularly raccoons and opossums. These animals typically aren’t seen very often, because they are active at night. A single opossum can carry as many as 1,000 adult fleas! An opossum walking through your backyard even just one time can drop many flea eggs into the grass or under shrubs as they pass through. * Non-treated pets in the household – most dogs are treated for fleas and ticks. Often, the cats in the household are not, especially if they are indoor only cats. * Non-treated pets in the neighborhood – you may be vigilant about treating your pets for fleas, but your neighbor(s) may not.
