Common dog parasites

They are small, discrete and are experts at avoiding detection. But look closely and you may find parasites hiding on your dog. External parasites like fleas, ticks and mites can be found hiding in your dog’s coat, or living on or in their skin, while internal parasites like heartworm and intestinal worms live inside their body. Whether internal or external, these parasites can all cause disease. That’s why you need to keep your dog protected, inside and out.

The flea lifecycle – break it to get rid of fleas

While you might not be surprised to find fleas on your dog, you may be surprised to learn that adult fleas (the ones you see) make up only about 5% of the total population. The remaining 95% (eggs, larvae and pupae) are found in carpets and bedding - in fact anywhere in your house! Each female flea can lay up to 50 eggs per day so it doesn’t take long for an infestation to take hold. NexGard^® for Dogs and NexGard SPECTRA^® for Dogs kill adult fleas fast, before they can start to lay eggs, helping protect your dog and its environment.

The Australian paralysis tick can be deadly

Australia is home to a number of tick species that can infest dogs. Of greatest concern is the deadly paralysis tick. They are found along the east coast and a single paralysis tick can kill a dog if left untreated. They are most common in spring and summer but can be found throughout the year, so any dog that lives in, or visits a paralysis tick area, should always be protected.

Engorged adult ticks can reach about 1 cm in length. The toxin can cause paralysis and even death if not treated quickly

Brown Dog Tick

Why protect against heartworm disease?

Heartworm disease is a serious and potentially fatal disease seen in all mainland states of Australia. Heartworm is transmitted by mosquitoes and causes no signs of illness initially. As they grow in the heart and blood vessels, they can cause severe lung and heart damage. Give your dog NexGard SPECTRA for Dogs or HeartGard^30® PLUS monthly to protect your dog against heartworm disease.

Intestinal worms

Intestinal worms are spread via dog faeces, so can be picked up anywhere from the backyard to the dog park. In very young dogs, or if present in high numbers, intestinal worms can cause gastrointestinal disease, malnutrition and anaemia. Some worms may also infect humans. NexGard SPECTRA for Dogs and ParaGard Allwormer for Dogs provide protection against the intestinal worms that commonly affect dogs in Australia.
