NexGard Spectra for large dogs is a monthly one-tablet treatment meant to treat and protect your dog from a range of both internal and external parasites. These primarily include: Fleas Ticks Lungworm Roundworm NexGard Spectra also protects your dog from demodex, sarcoptes, hookworms, whipworm and prevents heartworm. How Does NexGard Spectra Work? NexGard Spectra for dogs contain two active ingredients: afoxolaner and milbemycin oxime. The afoxolaner works by binding to GABA-gated and glutamate-gated chloride channels in insects and their nerve cells. The treatment is then able to attack the parasite's central nervous system, sending them into hyperexcitation which results in uncontrolled activity and death. The milbemycin oxime works in a similar way by disrupting nerve transmissions within the parasite, ultimately leading to their death. When working together, these two ingredients offer broad-spectrum treatment to protect your dog from both internal and external parasites for a month.
