Seresto Flea & Tick Collar for Dogs

Most flea treatments demand a monthly routine: topicals, pills, sprays. Seresto doesn't. One collar protects your dog for up to 8 continuous months with no monthly dosing, no mess, and no reminders to set.

How It Works

Seresto uses a slow-release matrix system that embeds two active ingredients, imidacloprid and flumethrin, directly into the collar material. These actives diffuse outward in low, continuous doses across your dog's coat and skin throughout the 8-month period. The result is consistent, low-level protection rather than the peaks and valleys of monthly treatments.

Fleas are killed within 24 hours of contact. Ticks within 48 hours. Re-infesting fleas are eliminated within 2 hours.

What It Protects Against

• Fleas: kills and repels for 8 months
• Ticks: kills and repels for 8 months
• Flea larvae in your dog's environment
• Lice

Designed for Real Life

The collar is odorless and non-greasy. No residue on furniture, no smell after petting your dog. It's water-resistant and remains effective after bathing, swimming, or rain exposure, though prolonged immersion may reduce the full 8-month duration.

A built-in safety release mechanism allows the collar to break away under sustained pressure, reducing the risk of entanglement. Reflective elements improve visibility in low light.

Which Size

Small collar fits dogs up to 18 lbs. Large collar fits dogs over 18 lbs. Both include an adjustable fit with a removable excess length to keep your dog comfortable.

The Truva Take

We carry Seresto because it's one of the few flea and tick products with a genuine clinical track record and a delivery mechanism that doesn't require you to remember a monthly schedule. For dogs who spend time outdoors, swim, or live in tick-heavy areas, it's the most practical long-term protection available.

Also worth pairing with our WizSmart training pads for households managing multiple pet care routines.
