10 common pet health issues in Australia (and how to prevent them)

Australia is one of the most pet-loving nations in the world, with dogs, cats, and even exotic pets becoming part of the family. But our unique climate, native wildlife, and outdoor lifestyle can expose pets to certain health risks – some minor, some potentially life-threatening.

Understanding the most common pet health problems and how to prevent them is key to keeping your furry friend safe, happy, and thriving.

Here are 10 of the most common pet illnesses and conditions seen across Australian households, plus tips on how you can reduce the risks.

1. Ticks and Fleas

Australia’s warm, humid environment is a haven for fleas and ticks. While fleas mainly cause discomfort, paralysis ticks can lead to vomiting, breathing difficulties, and even death – especially for dogs and cats on the east coast.

Prevention:

• Use year-round flea and tick prevention products like NexGard, Bravecto or Simparica.
• Check your pet daily, especially after walks in bushy or grassy areas.
• Keep your yard tidy and mow grass regularly.
• Brush and groom pets regularly to spot issues early.

2. Heatstroke

With Australia’s intense summer heat, heatstroke is a serious pet illness – particularly for dogs with thick coats or short noses (like bulldogs and pugs).

Prevention:

• Provide shade and plenty of fresh water.
• Walk pets in the early morning or late evening.
• Never leave pets in a parked car – even for a few minutes.
• Watch for signs like excessive panting, drooling, or lethargy.

3. Obesity

One of the most common pet health issues today is obesity. Excess weight can shorten your pet’s lifespan and contribute to conditions like diabetes, joint problems, and heart disease.

Prevention:

• Feed high-quality, portion-controlled meals.
• Avoid excessive treats or table scraps.
• Ensure daily exercise tailored to your pet’s age and breed.
• Ask your vet to assess your pet’s body condition score.

4. Dental Disease

Dental issues are among the most common pet illnesses seen in dogs and cats – especially as they age. In fact, 80% of cats show signs of dental disease by the age of three!

Plaque and tartar build-up can lead to gum disease, tooth loss, and infections that affect the heart and kidneys.

Prevention:

• Brush your pet’s teeth with pet-safe toothpaste.
• Offer dental chews or toys.
• Schedule professional dental cleans with your vet as needed.
• Watch for bad breath, drooling, or difficulty eating.

5. Snake Bites

Australia is home to some of the world’s deadliest snakes. Curious pets who poke around in long grass or bushland may be at risk of a venomous bite – a rare but serious pet illness that needs immediate attention.

Prevention:

• Keep dogs on a leash during bush walks.
• Clear tall grass and debris from your yard.
• Train pets to avoid snakes if you live in a high-risk area.
• Be alert in warmer months when snakes are more active.

6. Parvovirus

Parvovirus is a highly contagious and potentially deadly disease that mostly affects unvaccinated puppies and dogs. It causes severe vomiting, diarrhoea, and dehydration and spreads easily through infected poo or contaminated surfaces.

Prevention:

• Keep your dog’s vaccinations up to date.
• Avoid parks or public places until your puppy is fully vaccinated.
• Clean up after your dog to prevent spread in your community.
• Be aware of outbreaks in your area.

7. Ear Infections

Pets with floppy ears (like Cocker Spaniels) or water-loving breeds (like Labradors) are prone to ear infections. They’re one of the most common pet health problems, especially in warmer months.

Prevention:

• Gently clean ears with vet-recommended solutions.
• Dry your pet’s ears thoroughly after swimming or bathing.
• Avoid inserting cotton buds deep into the ear canal.
• Watch for head shaking, scratching, or a strong odour.

8. Arthritis

Arthritis is a common issue for older pets, affecting their joints and mobility. While not curable, it can be managed to improve comfort and quality of life.

Prevention:

• Keep your pet at a healthy weight to reduce joint strain.
• Use orthopaedic bedding for support.
• Provide vet-recommended joint supplements.
• Adjust exercise routines to suit your pet’s mobility.

9. Heartworm Disease

Heartworm is a serious pet illness caused by parasitic worms that live in the heart and lungs. It’s transmitted by mosquitoes and can be fatal if not treated.

Prevention:

• Use monthly heartworm preventatives (chews, tablets, or spot-on).
• Get annual heartworm tests through your vet.
• Reduce standing water around your home to deter mosquitoes.
• Be consistent – missing even one dose can leave your pet vulnerable.

10. Skin Allergies

From pollen to grass to certain foods, many pets suffer from skin allergies, especially in Australia’s diverse environment. Itchy skin, rashes, and hair loss are common symptoms.

As a pet insurer, we paid out more than $437,000 in claims for skin allergies alone in 2024.

Prevention:

• Bathe your pet with hypoallergenic shampoo.
• Use flea prevention – many skin issues are caused by flea saliva.
• Clean bedding regularly and vacuum often.
• Work with your vet to find and manage specific allergens.

General health tips for every pet

• Regular vet check-ups: Think of these as your pet’s annual physical. Catching issues early can make all the difference and even save a life.
• Top nutrition: Fuel their adventures with a balanced diet specifically tailored to their age and species. Good food equals good health.
• Always hydrated: Fresh, clean water isn’t just nice to have, it’s essential for all pets.
• Keep moving: Regular exercise keeps their body strong, while mental stimulation keeps their mind sharp. A bored pet can be a mischievous pet!
• Grooming: Brushing, nail trims, and coat care aren’t just for looks. They prevent painful issues and help you spot problems early.
