NexGard is a monthly beef-flavoured chewable parasite treatment for small dogs weighing between 4.1 and 10 kilograms. Given once a month, it protects against flea infestations, paralysis ticks, brown dog ticks, mites, lice, and flea tapeworms in a single chew. It is suitable for dogs over eight weeks of age.

The active ingredient, afoxolaner, works systemically — entering the dog's bloodstream so parasites are killed when they feed. Fleas are killed before they can lay eggs, interrupting the infestation cycle in the home environment. Paralysis tick coverage is relevant across much of coastal and eastern Australia, particularly during spring and summer. The chew is made from soy protein and accepted by most dogs without needing to be disguised.

For small breed owners who find topical spot-on treatments fiddly or stressful for the dog, a chew that most dogs accept readily removes a monthly source of friction. Consistent monthly dosing is straightforward, which helps owners stay on schedule with parasite prevention year-round.
