Protect from Fleas 

Fleas are more than just a nuisance, in some cases causing chronic skin disease and even transmitting infectious or parasitic diseases. Some of these can be transmitted to humans too.

NexGard SPECTRA kills fleas on dogs for 5 weeks (35 days), ensuring protection for a full month. By killing fleas fast, NexGard SPECTRA breaks the flea lifecycle, helping keep your dog healthy and your home flea free.

Through its rapid effect on fleas, NexGard SPECTRA also prevents the transmission of flea tapeworm.

Protect from Ticks

Australia is home to a number of tick species that can affect dogs. Of greatest concern is the potentially deadly paralysis tick which, each year, affects an estimated 10,000 dogs and cats.

A single adult female paralysis tick can kill a dog if left untreated, so preventative strategies are essential.

NexGard SPECTRA kills ticks on dogs (paralysis ticks, bush ticks and brown dog ticks) for 35 days (5 weeks) ensuring protection for a full month. To minimise the risk of tick paralysis, it’s also important to perform daily searching and removal of ticks.

Protect from Mites 

Mite infestation, also called mange, can cause severe skin or ear irritation and impact your dog’s quality of life.

Some mites, for example Sarcoptes scabiei, can also be transmitted from dogs to humans.

NexGard SPECTRA is an effective ear mite treatment for dogs. It also treats and controls demodectic mange caused by Demodex spp. and sarcoptic mange caused by Sarcoptes scabiei.

Protect from Lice

Lice are tiny insects that can cause skin irritation and hair loss.

NexGard SPECTRA treats and controls biting lice on dogs. To minimise the likelihood of lice reinfestation, it is important to treat all animals within a household with an approved lice control product.

Protect from Heartworm 

Heartworm disease is a serious and potentially fatal disease seen in all mainland states of Australia.

The worms, transmitted by mosquitoes, initially cause no signs of illness, but as they mature and grow in the heart and blood vessels, they can cause severe lung and heart damage.

NexGard SPECTRA, given monthly throughout the year, provides effective heartworm prevention for dogs.

Protect from Worms

Intestinal worms can affect all dogs and, when present in high numbers, can cause gastrointestinal disease, malnutrition and anaemia.

Some of these worms may also infest and cause disease in humans.

NexGard SPECTRA is an effective worm treatment for dogs. It treats and controls roundworm, hookworm and whipworm.  

The flea tapeworm is transmitted by fleas. Dogs become infested by ingesting adult fleas carrying the tapeworm larvae. Effective flea control with NexGard Spectra prevents new infestations. To treat an existing infestation, a product registered to treat flea tapeworm should be administered (e.g., ParaGard Allwormer for Dogs).
