Frequently Asked Questions

Q1: How long does Seresto Flea & Tick Collar protection last?

Ans: Each Seresto collar is designed to provide continuous flea and tick protection for up to 8 months when worn continuously. For ongoing prevention, replace the collar after the full protection period to maintain consistent coverage year-round.

Q2: What active ingredients are in the Seresto Flea & Tick Collar Bundle for Small & Large Dogs?

Ans: Seresto collars contain two active ingredients: imidacloprid (10.0%) and flumethrin (4.5%). These ingredients work together to kill and repel fleas and ticks by contact, supporting long-lasting protection with continuous wear.

Q3: Which dogs should wear the small vs. the large Seresto collar in the bundle?

Ans: Use the small-dog collar for dogs up to 18 lbs and the large-dog collar for dogs over 18 lbs. Both collars are intended for dogs and puppies 7 weeks of age and older when used as directed.

Q4: Can Seresto collars be worn during bathing or swimming?

Ans: Seresto collars are water-resistant and remain effective after exposure to rain, swimming, or shampooing. To help maintain an 8-month duration, limit bathing frequency to no more than once per month for dogs wearing the collar.

Q5: How should the Seresto collar fit on a dog’s neck?

Ans: Place the collar around the dog’s neck and adjust so two fingers fit comfortably between the collar and the neck. Thread the end through the loops, then trim excess length beyond the loops, leaving extra for growing puppies.

Q6: How often should Seresto collars be replaced?

Ans: Replace each Seresto collar after 8 months to continue flea and tick protection. Continuous wear supports the intended duration, and replacing on schedule helps maintain consistent control through changing seasons and parasite pressure.

Q8: What should pet parents do if side effects occur with a Seresto collar?

Ans: If a dog shows signs like itching, skin irritation, lethargy, or neurologic symptoms, remove the Seresto collar right away. Contact a veterinarian for advice and monitor the dog closely until signs resolve or further guidance is provided.
