What We’re Up Against in Sydney: The Big Three Pests
The Paralysis Tick: Our Most Dangerous Local Threat
The paralysis tick (Ixodes holocyclus) is the one we truly have to worry about. Found in the bushy areas we love, from the Northern Beaches to the Royal National Park, it injects a neurotoxin that can cause rapidly progressing paralysis and is often fatal if not treated immediately.

Fleas: The Source of Skin Problems
Fleas are the leading cause of skin disease in our pets. For some dogs with Flea Allergy Dermatitis (FAD), a single bite can trigger a miserable allergic reaction. Worse, the adult fleas on your dog are only 5% of the problem; the other 95% exists as eggs and larvae hidden in your home, according to Health Victoria.
Heartworm & Intestinal Worms
Transmitted by mosquitoes, heartworm is a silent and serious threat that causes severe lung and heart damage. Intestinal worms (like roundworm and hookworm) are common and can cause everything from diarrhoea to poor growth in puppies.
Decoding Your Options: A Guide to Treatment Types
Navigating the world of parasite prevention can be overwhelming. The primary methods of administration are oral treatments, topical spot-ons, and collars.
Oral Chews
These popular, beef-flavoured chews work systemically. They are incredibly convenient and don’t wash off, which is perfect for dogs who love swimming. The parasite does need to bite the dog to be affected.
Topical Spot-Ons
These are liquids applied to the skin. Some can repel parasites before they bite, a huge plus for allergic dogs. The downside is that they can be greasy, and you need to keep the area dry for a while after application.
Collars & Shampoos
Think of these as support tools. As explained by Australian vets at Greencross Vets, flea shampoos are fantastic for killing fleas that are on your dog right now but offer no real protection for tomorrow.

CRITICAL SAFETY WARNING
According to the Australian Animal Poisons Helpline, there is no scientific proof that home remedies like garlic, apple cider vinegar, or essential oils are effective at preventing the deadly Australian paralysis tick. Relying on them in a high-risk area like Sydney can have fatal consequences.

Your Year-Round Protection Schedule
Consistency is everything. Use this simple checklist as a starting point for a conversation with your vet.
- Monthly: Administer your chosen all-in-one chew (e.g., NexGard Spectra, Simparica Trio) for fleas, ticks, heartworm, and intestinal worms.
- Every 3 Months: If using a flea/tick-only product like Bravecto, remember to give a separate all-wormer tablet.
- Daily: Make a habit of doing a quick “finger walk” through your dog’s fur to check for ticks, especially after every walk in a bushy or grassy area.
In Case of Emergency: Sydney Vet Action Plan
