Product Detail: NexGard Spectra

NexGard Spectra

Get adequate treatment and prevention of flea infestations, control of ticks and mites, prevention of heartworm, and treatment and control of intestinal worms in dogs and puppies from 8 weeks of age with NexGard Spectra. NexGard Spectra rapidly kills adult fleas and is indicated for the treatment and prevention of flea (Ctenocephalides spp.) infestations, for the control of newly acquired adult fleas, and for the control of Flea Allergy Dermatitis (FAD). Following administration, fleas are killed within 6-8 hours. Rapid onset of action kills newly acquired fleas before they can lay eggs. Fleas can transmit flea tapeworm (Dipylidium caninum). 


How NexGard Spectra works

NexGard Spectra paralyzes parasitic organisms by interfering with the way signals are passed between nerve cells (neurotransmission) in the nervous system of parasites that live in the fur of animals, such as fleas and ticks, and then kills it. Afoxolaner kills fleas before they can lay eggs and so helps to reduce contamination of the dog's environment.

Effective flea control with NexGard Spectra prevents flea tapeworm infestation in dogs. NexGard Spectra treats and controls Paralysis ticks (Ixodes holocyclus), Brown Dog ticks (Rhipicephalus sanguineus), and Bush ticks (Haemaphysalis longicornis) for one month. NexGard Spectra provides effective control of pre-existing Paralysis tick infestations within 24 hours. Ixodes holocyclus ticks do not occur in Western Australia. In tick season, daily searching for, and removal of, any ticks found is recommended. NexGard Spectra treats and controls demodectic mange caused by Demodex spp., sarcoptic mange caused by Sarcoptes scabiei and ear mite (Otodectes cynotis) infestations. NexGard Spectra prevents heartworm disease caused by Dirofilaria immitis and treats and controls roundworms (Toxocara canis and Toxascaris leonina), hookworms (Ancylostoma caninum and A. ceylanicum) and whipworms (Trichuris vulpis).

Great product

I have been using this now for over 6 months and I?m very happy with results. It?s so much easier to give one pill instead of two when you have 4 dogs. The price is very reasonable and have been buying from them for a long time. I?m in the US and these are not available here and even if they were I wouldn?t buy anywhere else but pet shed!

Very Pleased

Have been using NexGard Spectra now for 2 years on both CBRs in south central WI. Although we live in the country, haven't yet found an attached tick on either of them.

Great stuff!

I'm in the US and it is nice to have a product that covers BOTH heartworm prevention and fleas and ticks in one chewable tablet. Combining them makes it cost effective, easy to administer and the dogs don't get suspicious lol. We recommend Nexgard Spectra to all our friends.

This is the first time i have tried Negard, but if this is effictive i will be really pleased. I keep getting sold different products such as flea collars, which i dont like and i just want something that wil cover fleas and ticks. Nexgard also has a degree of worming as well i believe.I had this recommended by a friend so am hopefull it will be a success. We are nearly 1 month into the first tablet and so far so good.
