Frequently Asked Questions

Q1: How quickly does the Seresto collar start working on fleas and ticks?

Ans: The collar begins killing existing fleas within 24 hours and ticks within 48 hours of application. Re-infesting fleas are eliminated within 2 hours of contact, providing immediate relief from active infestations while maintaining long-term protection.

Q2: Can my dog swim or get bathed while wearing the Seresto collar?

Ans: Yes, the collar is water-resistant and maintains effectiveness after occasional swimming or bathing. However, limit water exposure to once monthly maximum to preserve the full 8-month protection duration, as frequent wetting reduces effectiveness.

Q3: Is the Seresto collar safe for puppies, and at what age can they start wearing it?

Ans: The Seresto collar is safe for puppies 7 weeks of age and older, weighing over 18 pounds for the large size collar. Ensure proper fit and monitor growing puppies monthly to adjust collar size as needed.

Q4: Does the Seresto collar repel ticks or just kill them after they bite?

Ans: Seresto actively repels and kills ticks through contact action before they can attach and bite your dog. This contact-kill mechanism helps reduce the risk of tick-borne diseases by preventing tick attachment entirely.

Q5: What should I do if my dog shows skin irritation from the collar?

Ans: Remove the collar immediately if persistent redness, excessive scratching, or hair loss develops at the application site. Wash the area with mild soap and consult your veterinarian for proper evaluation and treatment recommendations.
