NexGard Chewables for Large Dogs are a once-monthly flea and tick preventive in a soft, beef-flavored chew. This Red pack is dosed for dogs weighing 60.1–121 lbs (25.1–50 kg). Doses should not be split or shared across sizes.
The active ingredient, afoxolaner, is absorbed into the dog's bloodstream after the chew is eaten. Fleas and ticks that bite ingest it and are killed. It starts working on fleas within 4 hours and kills 100% of fleas within 8 hours of dosing. It controls black-legged (deer) ticks, American dog ticks, lone star ticks and brown dog ticks.
Give one chew a month, on the same date each month. It can be offered as a treat or with food. Make sure the dog chews and swallows the full dose. Year-round dosing gives the best protection, especially in tick-active regions. The chew leaves no residue, so the dog can be bathed, can swim and can be petted right after dosing. It is for puppies and adult dogs 8 weeks and older, and owners of dogs with a history of seizures should consult a vet first.
