The end of winter is a cause for celebration for many pets, but as they rush back outdoors, they risk encountering spring’s many dangers.
From bloodsucking parasites to toxic plants, dogs and cats are exposed to a variety of threats that can lead to long-term health problems – or worse.
By being aware of the risks and taking preventative measures, you and your pets can enjoy the warmer weather, longer days and blooming blossoms of spring.
PESKY PARASITES
Spring brings with it a host of parasites looking to feed. Fleas, ticks and mosquitoes thrive as the weather warms up, and all expose our pets to more severe conditions.
Fleas can trigger flea allergy dermatitis, an allergic reaction in dogs and cats. Itchy or inflamed skin, hair loss, scabs and skin infections are common symptoms. Year-round flea control is an effective preventative measure, even if your pet doesn’t have a specific flea allergy.
Tick season is lasting longer and hitting harder than ever. Ticks thrive in humid environments, with Australia’s east coast a hotspot, and wait for victims in bushy areas or long grass. The paralysis tick is a particular danger; its bite can cause serious or even fatal illness in dogs and cats.
PetSure claims data* from 2019-2023 shows a clear seasonal trend for tick paralysis claims, starting in September and peaking in October. In recent years, however, tick season is lasting longer; cases begin as early as August and continue into December and January. In FY25, the average amount claimed for tick paralysis in dogs was $3,320, with the maximum nearly $57,480**.
The best way to keep your pet safe is a three-step process: use paralysis tick preventatives (chewable, topical and injectable); conduct regular and thorough tick searches after your pet has been outside; and know your ticks. If you’re able to remove an unattached tick on your pet, show it to your vet for identification. If the tick is attached, bring your pet to the vet for tick removal and identification.

If you notice any early warning signs of tick paralysis – uncoordinated movement, wobbly back legs, excessive coughing, difficulty breathing, reduced appetite, choking on water, vomiting or droopy facial features – seek veterinary attention urgently.
ANNOYING ALLERGIES
Humans aren’t the only ones hit hard by allergies as winter gives way to spring. When September rolls around, Aussie dogs and cats are likely to encounter a surge of pollen, dust mites or mould spores during their outdoor adventures, which can lead to big bills and chronic problems as the season rolls on. And just because your dog or cat isn’t sneezing and wheezing doesn’t mean they’re unaffected.

Atopic dermatitis, an inflammatory skin condition similar to human eczema, is a common response by pets to outdoor allergens. Easily missed beneath a thick furry coat, skin allergies can cause your pet significant discomfort and can easily escalate if left unchecked.
According to PetSure claims data from the 2025 Pet Health Monitor report, skin allergies and infections were the most claimed conditions for dogs in 2024, and the third most claimed condition for cats. Average cost of treatment in FY25 was $714 for dogs and $611 for cats, with the maximum cost being $17,375 and $10,991 respectively.^

Some skin allergies can develop into lifelong conditions requiring recurrent care over the pet’s lifetime. That’s why it’s important to check your pet regularly and take preventative steps throughout the year.
- Diligent skin and coat care, including ensuring hair is kept free of knots and matting.
- A healthy diet with adequate essential fatty acids, which optimise skin health.
- Get expert veterinary advice on potential skin allergies or any other aspect of your pet’s health.
SNAKE SEASON
Snake bites in dogs and cats occur much more frequently than you might expect. PetSure data shows that beginning in August, snake bite prevalence climbs rapidly as they emerge from winter hibernation.
Curious pets that encounter snakes in the springtime could require urgent veterinary treatment if bitten; venom can cause severe symptoms including paralysis and respiratory distress. Without immediate care, snake bites can be fatal.
While it’s impossible to eliminate all risks, consider these practical steps to reduce the chance of a snake bite:
- Stick to designated paths and avoid long grass.
- Maintain your backyard. Remove debris and keep your lawn trimmed.
- Supervise outdoor time for your pets.
- Be aware of snake bite symptoms – weakness in the legs, vomiting, swollen visible bite marks – and be prepared to act quickly.
POISONOUS PLANTS
It’s great for our pets to be back in the sunshine in the wake of winter, but a spring garden can contain botanical dangers as well.
Many plants can be toxic to pets, particularly young animals that still love to chew everything. Even species that seem benign to humans carry a risk: aloe, yucca, agave and tulips are some that can cause vomiting, weakness, liver damage and seizures.
PetSure claims data from 2025 indicates the average treatment cost relating to plant toxicities was $797 for dogs and $1,675 for cats. The highest claims were $28,885 for dogs and $7,312 for cats, so once again, prevention is crucial.^^
Monitor your pet’s activity outside, pet-proof your garden by removing any toxic plants, and as always, be ready to act if any toxin is ingested. Rinse your pet’s mouth with water or milk and visit your local vet with samples of the offending plant.
Spring may only come once a year, but its effects can last a lifetime. With so much at stake, it’s important to be vigilant, know the signs and stay safe this spring.
