By Dial A Vet Veterinary Team
It is a common late-night search: your dog has a sore ear, a weeping wound or is straining to wee, and you want something now. In Australia, the short answer is no. Antibiotics for animals are prescription-only medicines, and a veterinarian needs to assess your dog before prescribing one. That can feel like a hurdle when you are worried, but it protects your dog from the wrong treatment and helps keep antibiotics working for animals and people.
Key takeaways
- Antibiotics for dogs are prescription-only in Australia. Legitimate Australian pharmacies and pet pharmacies require a valid veterinary prescription.
- Products sold online without a prescription, especially from overseas, may be the wrong drug, the wrong strength, counterfeit or contaminated.
- Leftover antibiotics, human antibiotics and another pet's medicine are not safe substitutes.
- Many problems that look like infections are not bacterial and will not respond to antibiotics.
- Related: antibiotics for dogs, urinary tract infections, minor wound care.
Why antibiotics need a prescription
Antibiotics are scheduled medicines under Australia's Poisons Standard. For animals, a vet can only prescribe them for patients under their care. There are good clinical reasons behind that:
- The problem might not be bacterial. Itchy skin is often allergy. Many coughs are viral. Most diarrhoea is not caused by bacteria that need antibiotics.
- The drug has to match the infection. Different antibiotics reach different tissues and target different bacteria. A medicine that works in the bladder may do little for an ear or a bone.
- The course length matters. Too short can let the infection rebound. Too long adds side effects and resistance.
- Some dogs should not have certain drugs. Age, breed, pregnancy, kidney or liver disease and other medicines all change what is safe.
- Resistance is real. Resistant bacteria are now seen in Australian dogs, particularly in skin infections. Unnecessary or incorrect use speeds that up.
The risks of the shortcuts
Leftover antibiotics
Leftovers are often from a different problem, an incomplete course or past their expiry date. Starting and stopping a partial course can also make a later culture test harder to interpret.
Human antibiotics
Human tablets and liquids may be the wrong drug or strength for a dog. Some human liquid medicines contain xylitol, which is highly toxic to dogs. Never give your own medicine to your pet.
Overseas websites and "no prescription" sellers
Medicines bought online without a prescription may not be what the label says. Quality, storage and contents can be unknown, and importing some medicines can breach Australian rules. If something goes wrong, your vet will not know what your dog actually received.
Another pet's medicine
Medicines and amounts are chosen for one animal's weight and condition. Sharing can lead to underdosing, overdosing or using the wrong medicine.
Signs your dog needs to be seen
- A wound that is red, swollen, hot, smelly or discharging
- Ear head-shaking, odour or discharge
- Straining to urinate, frequent small wees or blood in the urine
- Coughing with lethargy, fever or reduced appetite
- Pimples, crusts or scabs spreading over the skin
- A painful swelling, which may be an abscess
When it is an emergency
Go to a vet now if your dog has difficulty breathing, collapses, has pale gums, is straining to urinate with little or nothing coming out (especially male dogs), has a deep or bleeding wound, or has vomiting with lethargy. These situations need hands-on care, not a home remedy.
Faster, legitimate options
- Call your regular clinic and explain your concern. Many keep same-day appointments for urgent cases.
- After-hours and emergency hospitals can see your dog when your clinic is closed.
- Telehealth. A video consult can help you decide how urgent the problem is, what you can safely do at home in the meantime and what to tell the clinic. In Australia, whether a vet can prescribe after a remote consult depends on state rules and whether the dog is already under that vet's care. Often the next step is an in-clinic examination.
- Online pet pharmacies can fill a valid prescription from your vet, sometimes at lower cost for long courses.
What you can do while you wait
- Keep wounds clean and stop your dog licking them, using a cone if you have one.
- Keep your dog comfortable and quiet.
- Note when signs started and take photos to show the vet.
- Do not apply human creams, tea tree oil or other essential oils.
FAQ
Can a pet shop sell me antibiotics for my dog?
Not prescription antibiotics. Over-the-counter products are not a substitute for a vet's assessment.
Can my vet give me antibiotics over the phone?
That depends on whether your dog has been examined recently and on state regulations. Your vet will usually need to see your dog for a new problem.
Are "natural antibiotics" like honey or garlic safe?
Garlic is toxic to dogs. Some medical-grade honey products are used in wound care under vet guidance, but kitchen remedies are not a replacement for treatment.
Why is the vet consult necessary if I already know it is an ear infection?
Ear problems vary. The vet checks the eardrum and what kind of organisms are present, which changes the treatment.
