NexGard Spectra Chewable Tablets for Large Dogs 15.1 - 30kg (Purple) 3pk
Rated 5/5 based on 10 reviews.NexGard Spectra Chewable Tablets for Large Dogs (Purple) provide complete protection against fleas, ticks, heartworm, intestinal worms, and mites for dogs weighing 15.1–30 kg. With a single beef-flavoured chew each month, your dog receives all-in-one parasite control, eliminating the need for multiple treatments, spot-ons, sprays, or collars.
Suitable for puppies from 8 weeks of age, NexGard Spectra ensures safe, effective parasite protection for both growing puppies and adult dogs.
Key Benefits
Protect Against Fleas
NexGard Spectra kills adult fleas before they lay eggs, breaking the flea lifecycle and preventing infestations in your home. Fleas can cause skin irritation, transmit diseases, and lead to anaemia in heavy infestations. Regular monthly treatment keeps both your dog and household safe.
Protect Against Ticks
One chew protects against paralysis ticks, bush ticks, and brown dog ticks for a full month. Paralysis ticks are particularly dangerous, and untreated bites can be fatal. Brown dog ticks can transmit other parasites, including Babesia, and may cause anaemia when infestations are heavy.
Protect Against Heartworm
NexGard Spectra prevents heartworm disease, a potentially fatal condition spread by mosquitoes. Your veterinarian may recommend a heartworm test before starting treatment. Monthly dosing ensures continuous protection.
Protect Against Intestinal Worms
NexGard Spectra treats and controls roundworms, hookworms, and whipworms, preventing nutrient loss, anaemia, and gastrointestinal disease. Effective flea control also helps prevent flea tapeworm (Dipylidium caninum) infestations. Consult your veterinarian for region-specific deworming advice.
Protect Against Mites
NexGard Spectra treats and controls demodectic mange, sarcoptic mange, and ear mites (Otodectes cynotis), supporting healthy skin and ears.
How NexGard Spectra Works
NexGard Spectra combines two active ingredients:
- Afoxolaner – An ectoparasiticide that kills fleas, ticks, and mites quickly when they attempt to feed.
- Milbemycin Oxime – An endoparasiticide that targets internal worms such as roundworms, hookworms, and whipworms.
This combination ensures all-in-one parasite protection with a single monthly chew.

All in one monthly treatment
By: Hayley on 24 November 2018This is the only brand I buy for my dog now, it's all the treatment she needs in one convenient monthly dose. As it looks like a treat my dog has no issues consuming it whereas with tablets I used to have to hide them in her food. More cost efficient buying it this way also rather than buying 2 separate tablets.
