By Dial A Vet Veterinary Team
A heavy flea or hookworm burden can make a young puppy dangerously anaemic in a matter of days, because there is so little blood volume to spare. Many puppies are also born with roundworm larvae passed from their mother. Parasite control in the first months of life is therefore one of the most practical things you can do for your puppy's growth and comfort, and for your family's health too.
Key takeaways
- Most puppies carry roundworms at birth or soon after, so regular worming starts early and continues through growth.
- Fleas cause itch, skin disease and anaemia, and they carry tapeworm.
- Paralysis ticks (Ixodes holocyclus) on the east coast of Australia can kill a puppy within days. Daily tick searches matter even with prevention.
- Heartworm is spread by mosquitoes and is still present in parts of Australia, so prevention is recommended.
- Puppy-safe products depend on age and weight. Never use adult dog products, cat products or home remedies without vet advice.
The common puppy parasites
Intestinal worms
Roundworms, hookworms, whipworms and tapeworms live in the gut. Roundworms are the most common in puppies and can be passed from mother to pup before birth and through milk. Hookworms feed on blood and are a particular concern in warm, humid parts of Australia. Signs include a pot belly, poor growth, a dull coat, diarrhoea, and sometimes visible worms in vomit or stool. Some roundworm and hookworm species can also infect people, which is one more reason to keep up with worming and pick up after your puppy promptly.
Fleas
Fleas cause scratching, small scabs, flea dirt (black specks that turn red on damp paper) and, in heavy infestations, pale gums from blood loss. Only a small share of a flea population lives on the pet; most of it sits in the house and yard as eggs, larvae and pupae. Our article on the flea life cycle explains why treating the environment matters.
Ticks
Brown dog ticks and bush ticks are irritating, but the paralysis tick is the one that worries Australian vets. It is found along the eastern seaboard from north Queensland to eastern Victoria, especially in bushland and coastal areas. Signs of tick paralysis include a change in bark, wobbly back legs, coughing, gagging or vomiting, and laboured breathing. See our guide to tick paralysis in dogs.
Heartworm
Heartworm larvae are spread by mosquito bites and grow into worms that live in the heart and lung vessels. Disease develops slowly over months, so puppies rarely show signs early, but prevention should begin young as advised by your vet.
Mites
Ear mites cause head shaking and dark, crumbly ear discharge. Demodex mites can cause patchy hair loss in young dogs, often around the face and front legs. Sarcoptic mange causes intense itch and is contagious to other dogs and, briefly, to people.
When to see a vet
Emergency now: any sign of tick paralysis, pale or white gums, collapse, severe weakness, or bloody diarrhoea in a young puppy. Puppies decline fast.
Same day: persistent diarrhoea or vomiting, a found tick even if the puppy seems well, heavy flea burden on a very young or small puppy, or sudden intense itch.
Can wait for a routine appointment: mild scratching, a patch of hair loss without itch, or questions about which products suit your puppy's age.
What you can do at home
- Run your fingers over your puppy's whole body every day in tick areas, including between the toes, inside the ears, under the collar and around the lips.
- If you find a tick, remove it with a tick remover or fine tweezers close to the skin, keep it in a jar for identification, and call your vet.
- Wash bedding hot and vacuum regularly during flea treatment.
- Pick up stools daily and wash hands after handling your puppy, especially for children.
- Do not use essential oils, tea tree oil or kerosene for parasites. These can be toxic to puppies.
How vets diagnose and treat parasites
Your vet will examine the coat and skin, look in the ears, and may test a stool sample for worm eggs. Skin scrapings or tape tests help identify mites. Treatment uses registered parasite products chosen for your puppy's age and weight, sometimes alongside care for skin infection or anaemia. A puppy with tick paralysis needs hospital care, including tick antiserum and close monitoring of breathing.
Prevention plan
Your vet will tailor a schedule to where you live and your puppy's lifestyle. In general it covers:
- Regular intestinal worming through puppyhood, then ongoing worming as an adult. Our worming Q and A covers common questions.
- Year-round flea control.
- Paralysis tick prevention in tick areas, plus daily searches.
- Heartworm prevention started at the age your vet recommends.
FAQ
Can my puppy give me worms?
Some dog roundworms and hookworms can infect people, especially children. Good hygiene and regular worming reduce the risk. See your GP with any health concerns of your own.
Are combination chews safe for puppies?
Many are registered for puppies above a certain age and weight. Check with your vet before starting, as the right choice depends on your puppy.
Do indoor puppies need parasite prevention?
Yes. Fleas and mosquitoes come indoors, and puppies go outside for toilet breaks and walks.
How do I know a tick is a paralysis tick?
It can be hard to tell, especially once engorged. Treat any tick found in a paralysis tick area as potentially dangerous and call your vet.
Talk with a vet
Not sure which parasite products suit your puppy, or found something odd in the coat or stool? A Dial A Vet veterinarian can help you build a prevention plan and decide whether your puppy needs to be seen. Book a Dial A Vet consult. Signs of tick paralysis, collapse or breathing trouble need an in-person emergency vet straight away.
