NexGard Spectra Chews in the Small & Large Dogs Bundle is a combined pack suited to multi-dog households running dogs in different weight tiers. It delivers the same all-in-one monthly parasite protection — fleas, ticks, heartworm, and intestinal worms — across both size ranges in a single purchase.

Each beef-flavoured chew combines afoxolaner and milbemycin oxime: afoxolaner kills fleas rapidly and controls paralysis ticks, brown dog ticks, and bush ticks for a full month, while milbemycin handles heartworm prevention and intestinal worm treatment (roundworm, hookworm, whipworm). The chew is designed to be accepted as a treat, and the bundle format saves multi-dog households from sourcing each weight tier separately.

Multi-dog households often end up buying two or three separate packs at different times, which makes it easy to fall out of sync on dosing schedules. A bundle pack keeps all dogs in the house on the same monthly routine.
