NexGard Chew for Dogs is a palatable beef-flavored chew, formulated to protect dogs against a range of external parasites. This monthly treatment is suitable for puppies and dogs from 8 weeks of age, weighing at least 4 lbs. The chew formula kills adult fleas and treats and prevents flea infestations. NexGard Chew for Dogs also treats and controls tick infestations caused by black-legged ticks, American dog ticks, lone star ticks, brown dog ticks and longhorned ticks. The treatment is also indicated for the prevention of Lyme disease infections due to killing black-legged ticks.
NexGard flea treatment for dogs features afoxolaner as its active ingredient. It is a member of the isoxazoline family, shown to inhibit insect and acarine ligand-gated chloride channels and block pre- and post-synaptic transfer of chloride ions across cell membranes. This afoxolaner-induced hyperexcitation causes uncontrolled activity of the central nervous system of the parasites and death of insects and acarine.

My dog actually enjoys taking Nexgard! Fleas and ticks haven’t been a problem since we started. Peace of mind for me and zero stress for him.
