NexGard Spectra® Chewable Tablets for Dogs — Flea, Tick, Heartworm & Dewormer

NexGard Spectra is a once-monthly chewable that gives dogs broad parasite coverage in a single beef-flavored tablet. It's built around two active ingredients — afoxolaner and milbemycin oxime — that work together to:

• Kill fleas before they can lay eggs, breaking the flea life cycle rather than just treating an active infestation
• Eliminate ticks and mites
• Prevent heartworm disease, along with lungworm and eyeworm infections
• Treat and control intestinal worms — hookworms, roundworms, whipworms, and lungworms

Dosing is based on your dog's weight, so the correct tablet strength matters — select your dog's weight range above. NexGard Spectra is prescription-only in Canada; your pharmacist will confirm the exact dose against your veterinarian's prescription before dispensing.
