Kills intestinal worms

NEXGARD SPECTRA provides excellent protection from roundworms, hookworms AND whipworms. As with most products for treating worms in dogs, only worms present at the time of treatment are killed. After that, dogs can pick up new worms. Roundworm is an important species to protect against. Once in a dog, a female roundworm can start shedding eggs within 4-5 weeks. These are a zoonotic risk to humans, so it is important to de-worm monthly to minimise this risk.
