How to Choose the Right Flea, Tick, and Worm Treatment for Your Pet in New Zealand

If you’ve ever stood in front of a wall of pet treatments and wondered which one to buy, you’re not alone. With so many brands claiming to do it all, it can be tricky to know what’s right for your dog or cat.

The good news is that there’s a simple way to make the right choice. Let’s go through what matters most for New Zealand pet owners.

Why Every Pet Needs Year-Round Protection

New Zealand’s mild climate means fleas and worms never truly disappear, even in winter. Fleas can live inside your home, in carpets and bedding, while worms can spread from the soil, prey animals, or even other pets.

Ticks are also becoming more common, especially in coastal and rural areas. Consistent protection keeps your pets healthy and prevents infestations before they start.

Step 1: Know What You Need to Protect Against

Different products cover different parasites. Check the label or description carefully.

• Fleas: Cause itching, skin infections, and allergies.

• Ticks: Spread diseases and cause anaemia.

• Intestinal worms: Lead to weight loss, vomiting, and poor condition.

• Heartworm: Is present Australia and is not established in New Zealand, but dog's have tested positive for heartworm before. 

The best products combine all these protections in one easy treatment.

Step 2: Consider Your Pet’s Lifestyle

• Indoor pets: Still need flea and worm protection, but may not need heavy tick coverage.

• Outdoor pets: Need full protection against fleas, ticks, and worms.

• Multi-pet households: Treat every pet, even if only one goes outside.

If your pets play together, share beds, or groom each other, they can easily share parasites too.

Step 3: Choose the Right Type of Treatment

You’ll find two main types:

• Oral chews: Dogs love them, and they provide consistent coverage without washing off. Great examples are NexGard Spectra and Bravecto.

• Spot-on liquids: Applied to the back of the neck. They’re perfect for cats or dogs that won’t take tablets. Options include Revolution Plus, Advocate, and Advantage.

Both are safe and effective when used correctly. The right choice often depends on what’s easiest for you and your pet.

Step 4: Match the Product to Your Pet’s Size and Age

Always choose the correct pack for your pet’s weight. Using the wrong size can reduce effectiveness or cause side effects.
Most products can be used on puppies or kittens from 8 weeks of age, but check the label for age and weight limits.

Step 5: Stay Consistent

The biggest mistake pet owners make is forgetting doses. Set a monthly reminder or subscribe for automatic deliveries. Missing even one dose can allow fleas or worms to come back.

Products like NexGard Spectra and Bravecto make it easier to stay on track because they last longer and combine multiple protections in one.
