Tick tock: Is your dog’s flea and tick treatment up-to-date?

Flea and tick prevention might not be the most glamorous part of pet parenthood, but trust us, it’s super important. Especially as dog owners in Aotearoa have recently been issued an important reminder following the detection of Babesia gibsoni, a tick-borne disease, in the Canterbury region.
While tick-borne illnesses in dogs aren't widespread in New Zealand, this detection serves as a wake-up call for pet owners across the country to prioritise flea and tick prevention. Our friend and resident expert Dr. Rosalind Holland (BVSc), offers us some valuable insight on this topic as we break down everything you need to know about flea and tick treatment for your dog.
The importance of flea and tick prevention
Fleas and ticks on dogs may seem like minor nuisances, but they can have a significant impact on your dog’s health and welfare, and be unpleasant for owners to deal with, explains Dr. Holland.
Fleas are universal pests – no matter where you live in New Zealand, your dog is at risk if not protected. These tiny bloodsuckers can cause irritations, allergic reactions, and even anaemia in severe infestations. Ticks, on the other hand, tend to be location-specific. They are more prevalent in the North Island but can also be found throughout the South Island, particularly in coastal areas.
While tick-borne illnesses like Babesia gibsoni are uncommon in New Zealand, the recent detection in Canterbury highlights the need for vigilance. Ticks not only irritate your pet but can also pose long-term health risks if left untreated.
Regular treatment isn’t just about keeping your pet healthy. It’s also about maintaining a clean, parasite-free home. Fleas don’t just live on your dog – they lay eggs in your carpets, bedding, and furniture, creating a never-ending cycle if not properly addressed.
Popular treatment options for fleas and ticks
So, how exactly can you keep fleas and ticks at bay? Thankfully, there are plenty of treatment options available to prevent and manage these pests.
Dr. Holland explains: "There are several over-the-counter products that effectively treat and prevent fleas and ticks. Ticks are generally harder to kill than fleas so not all flea products will also target ticks."
Dual flea and tick treatments
For comprehensive protection, look for products that address both fleas and ticks. There are many popular options available in New Zealand, but check with your pet’s vet on what may be a suitable option for them.
These products come in various formulations, whether oral tablets, tasty chewable treats, or topical spot-on applications and have different durations of action. Finding the right one for your dog will depend on factors such as their size, age, and preferences (or their willingness to take tablets!).
Treating the environment
If your dog already has a significant flea or tick burden, treating your home environment is essential. Flea eggs and larvae can hide in carpets, bedding, and furniture, so a thorough cleaning and targeted pest control may be required to fully eliminate an infestation. It’s also important to note that if you are a multi-pet household, all your animals should be treated at the same time to help break the flea life cycle.
What to look for when choosing flea and tick products
Walking into a pet store or vet clinic and seeing rows of flea and tick treatments can feel a bit overwhelming. Here are a few key factors to consider when making your decision.
Oral vs. topical formulations
Flea and tick treatments come in two main forms – oral treatments, and topical spot-on solutions. Both are effective, but one may be more practical than the other depending on your dog’s needs.
- Oral treatments: Dr. Holland mentions that oral formulations can be both unflavoured tablets or chewable flavoured treats, which can be a bit of a treat for most dogs.
- Topical solutions: If oral treatments aren’t an option for your pup, spot-on treatments that are applied directly to their skin can be just as effective. They’re quick, easy, and ideal for dogs who might turn their nose up at oral medications.
Ingredients and dosages
Different brands of flea and tick products will use different active ingredients, so it’s important to know which ones work best for your dog. Dr Holland recommends talking to your vet about what ingredients and dosages are safe and effective for your dog’s breed, age, and weight. Some breeds, like Collies, have a genetic mutation that makes them sensitive to certain drugs. It’s also essential to follow the instructions carefully and never use products meant for other animals on your dog.
Consider your dog's lifestyle
If your dog loves swimming or frequently plays outdoors in areas where fleas and ticks are common, oral treatments may be a better choice. Pets shouldn’t swim, be bathed, or go to the groomers for a few days after the treatment (please check the leaflet for details) as topical treatments can cause pollution of waterways.
Duration of protection
Not all flea and tick treatments last the same amount of time. Some products offer month-long protection, while others can last for up to three months. Consider your schedule and how often you’re able to administer treatments. Like vaccinations, flea and tick prevention is part of a dog's ongoing care.
Consult your vet for personalised recommendations
There’s no one-size-fits-all approach to flea and tick prevention, which is why it’s always a good idea to consult your vet who assesses your dog’s specific needs and environment to recommend the best products for them.
Your vet can also provide guidance on managing infestations if your home or pet is already inflicted with fleas or ticks. This personalised advice is invaluable in keeping your dog happy, healthy, and itch-free.
Keep fleas and ticks off the radar
The detection of Babesia gibsoni in Canterbury is a timely reminder for all dog owners in New Zealand to take flea and tick prevention seriously. While parasites like ticks might feel like minor irritants, they can lead to significant health issues if left unchecked.
Taking proactive steps with regular treatments will ensure your dog stays protected year-round. Whether it’s choosing the right product, maintaining your home’s cleanliness, or consulting your vet, every action contributes to your pup’s overall well-being – and your peace of mind. Another way to keep your pet protected is by considering pet insurance. SPCA Pet Insurance offers three levels of cover to ensure your furry friend is well taken care of.
