Common Puppy Health Problems: A Guide for New Owners

By Charlotte Bryan · 11 June 2026

Welcoming a new puppy to your Sunshine Coast home is an exciting milestone, but it also comes with the responsibility of monitoring their health. Young puppies have developing immune systems, making them more susceptible to various ailments. In this guide, we explore the most common health issues you might encounter during your pup's first year. From digestive upsets to local environmental risks like paralysis ticks, knowing what to look for ensures your furry friend gets the care they need quickly.

Key takeaways

  • Always maintain a strict parasite prevention schedule for ticks, fleas, and worms.
  • Monitor stools and appetite daily; small changes can signal early health issues.
  • Complete the full vaccination course before visiting high-traffic dog areas.
  • Check your puppy's body and ears daily to catch lumps, bumps, or ticks early.
  • Ensure your puppy stays cool and hydrated to prevent heatstroke in the Queensland climate.

Gastrointestinal Upsets and Diarrhoea

Tummy troubles are perhaps the most frequent issue puppy owners face. Because puppies are naturally curious, they often use their mouths to explore the world, leading them to swallow things they shouldn't.

Common causes of diarrhoea in puppies include:

  • Dietary Indiscretion: Eating rich human food, scraps from the BBQ, or items found in the garden.
  • Rapid Diet Changes: Switching kibble brands too quickly without a transition period.
  • Stress: Moving to a new home or meeting too many new people at once can trigger 'stress colitis'.
  • Parasites: Intestinal worms like roundworm or hookworm.

If your puppy is still energetic and drinking water, a bland diet of boiled chicken and white rice for 24 hours may help. However, if they are lethargic, vomiting, or have blood in their stool, visit your local Sunshine Coast vet immediately. Dehydration happens very quickly in small bodies.

Parasites: Ticks, Fleas, and Worms

In Queensland, parasite prevention isn't optional; it's a necessity. Our warm, humid climate is the perfect breeding ground for pests that can cause serious illness.

Paralysis Ticks: These are a major concern on the Sunshine Coast. These ticks secrete a neurotoxin that causes progressive paralysis. Check your puppy daily by performing a 'finger-tip search' through their coat, especially around the face, ears, and chest. If you notice a change in their bark, wobbly back legs, or coughing, seek emergency vet care.

Intestinal Worms: Most puppies are born with worms or contract them via milk. Symptoms include a 'pot-bellied' appearance, weight loss, or scooting their bottom on the grass. Ensure you follow a strict worming schedule, usually every two weeks until they are twelve weeks old.

Heartworm: Spread by mosquitoes, heartworm is a life-threatening condition. Prevention is simple via monthly chews or an annual injection from your vet.

Infectious Diseases and the Importance of Vaccinations

Until your puppy has finished their full course of vaccinations (usually around 16 weeks), they are vulnerable to highly contagious diseases. This is why we strictly control the environment in our puppy school to keep everyone safe.

  • Parvovirus: A devastating virus that attacks the gastrointestinal tract. It is hardy and can live in the soil for years. Symptoms include severe vomiting and foul-smelling, bloody diarrhoea.
  • Kennel Cough: Much like a human cold, this respiratory infection causes a dry, hacking cough. While rarely fatal, it is very uncomfortable and highly contagious.
  • Leptospirosis: Often found in areas with stagnant water or wildlife (like rats), this can cause kidney and liver failure.

Avoid taking your puppy to public parks or 'dog beaches' until your vet gives the all-clear after their final puppy booster. Socialisation is still vital, but it must be managed in safe, sanitised environments like our private sessions.

Skin Irritations and Allergies

Is your puppy constantly scratching or licking their paws? Skin issues are incredibly common, particularly in breeds like Staffies, Retrievers, and French Bulldogs. On the Sunshine Coast, environmental triggers like Wandering Jew (a common garden weed) or certain grasses can cause contact dermatitis.

Look out for red, inflamed skin, hair loss, or a 'yeasty' smell from the ears. Ear infections often go hand-in-hand with skin allergies. If your pup is shaking their head or has dark discharge in their ears, they likely need medicated drops. Maintaining a clean coat with soap-free, hypoallergenic shampoos can help, but chronic itching usually requires a vet-managed allergy plan.

Puppy Teething and Mouth Health

Between four and six months of age, your puppy will lose their needle-sharp baby teeth to make room for 42 adult teeth. This process can be uncomfortable, leading to some 'mouthiness' and red, swollen gums.

You might notice:

  • Increased chewing on furniture or shoes.
  • A small amount of bleeding from the gums (often seen on chew toys).
  • Slightly smelly breath.

To help, provide cold or frozen chew toys. A damp, twisted washcloth that has been frozen is a great DIY soother. If you notice 'retained' baby teeth—where the adult tooth grows in but the baby tooth refuses to fall out—consult your vet, as this can cause overcrowding and future dental decay.

Heatstroke and Sun Safety

Our beautiful Queensland sun can be dangerous for young pups. Puppies cannot regulate their body temperature as efficiently as adult dogs. They don't sweat like we do; they rely on panting to cool down.

Heatstroke can occur during a walk in the middle of the day or even if they are left in a poorly ventilated room. Signs include excessive panting, bright red gums, drooling, and weakness. Always provide plenty of shade and fresh water. If you are walking your pup, use the 'five-second rule': touch the pavement with the back of your hand. If it's too hot for you to hold for five seconds, it's too hot for their sensitive paw pads.

Frequently asked questions

How do I know if my puppy's diarrhoea is an emergency?

If your puppy is vomiting, appears lethargic, has pale gums, or there is blood in the stool, it is an emergency. Puppies can become dehydrated within hours. If it is just a single bout of soft stool and they are still playful and eating, monitor them closely and consult your vet if it persists for more than 24 hours.

Can I take my puppy for walks before their final vaccinations?

We recommend avoiding public areas where unknown dogs frequent until two weeks after their final puppy vaccination. However, socialisation is time-sensitive. You can carry your puppy in public, take them for car rides, or visit 'safe' friends who have fully vaccinated, healthy dogs. This builds confidence without risking exposure to diseases like Parvovirus.

What should I do if I find a tick on my puppy?

Use a tick removal tool or tweezers to grasp the tick as close to the skin as possible and pull upwards with steady pressure. Save the tick in a jar. Even if you remove it, monitor your puppy closely for the next 48 hours for any signs of wobbliness, vomiting, or breathing changes, as the toxin may already be in their system.

Why is my puppy constantly licking their paws?

Paw licking is often a sign of environmental allergies or contact dermatitis. They may have stepped in something irritating or have a reaction to local pollens. It can also be a sign of boredom or anxiety. If the paws are red or the fur is staining brown from saliva, a vet check is needed to rule out fungal infections.
