How long does a Seresto dog collar last?

Up to 8 months of continuous protection.

Is Seresto safe for all dogs?

Yes, it’s widely trusted. As with any product, monitor for skin irritation or allergies.

The collar is water-resistant and remains effective after exposure to water. For best longevity, remove it during long baths or heavy water play.

No—Seresto is available over the counter.

It releases controlled doses of active ingredients that target fleas & ticks at multiple life stages.

It should be snug but not tight—leave room for two fingers between collar and neck.
