By Dial A Vet Veterinary Team
Cannabis products are more common in Australian homes as laws and access change by jurisdiction, but toxicity for dogs remains real. Dogs that eat dried flower, butts, oils, butter, or especially THC edibles can become heavily sedated, wobbly, and distressed. Chocolate brownies and xylitol-sweetened gummies add second toxins. Veterinary teams have seen this often; honesty helps your dog more than embarrassment slows the call.
Key takeaways
- THC can cause sedation, dilated pupils, urinary dribbling, wobbliness, and rarely seizures.
- Edibles and concentrated oils are higher risk than a sniff of smoke alone.
- Call your vet or Animal Poisons Helpline (1300 869 738) with product type and amount.
- Do not induce vomiting with salt or peroxide unless directed; some timings and products make it unsafe.
- Related: marijuana and cats, marijuana effects in dogs, signs of poisoning.
What dogs usually get into
- Unattended jars of flower or ground material
- Infused butter or oil in the fridge
- Gummies, chocolates, and baked edibles (often the worst)
- Ashtrays and discarded butts at parties
- Vape liquid spills (nicotine may also be present in some devices; say so)
Signs of cannabis exposure
Glassy or dilated eyes, dribbling urine, slow responses, wobbly gait as if drunk, low or high heart rate changes, vomiting, sensitivity to touch or sound, and in severe cases tremors or seizures. Signs can last many hours. Related: chocolate risk if brownies were involved.
When it is an emergency
Collapse, seizures, severe agitation, trouble breathing, very small dogs with concentrated oil or many gummies, or mixed toxins (chocolate, xylitol, chocolate and raisins): emergency clinic with the packaging.
Immediate steps
- Move remaining product out of reach (use gloves if sticky oils).
- Note form (flower, edible, oil), estimated amount, and time.
- Call 1300 869 738 or your vet.
- Keep the dog in a quiet, safe space away from stairs and pools.
- Do not give human cannabis "antidotes," alcohol, or coffee.
Veterinary care
Supportive care is the mainstay: monitoring, anti-nausea medicine when needed, fluids, temperature support, and seizure control if required. Activated charcoal or controlled decontamination may be used when appropriate. Clinics focus on recovery, not policing your household.
Prevention and Australian context
Store all cannabis products in latching, child-proof containers inside cupboards pets cannot open. Edibles should be treated like medicine cabinets, not snack drawers. Legal status varies by state and product type; toxicity does not care about your local rules. Tell guests where the dog-safe zones are during parties.
Practical notes for Australian homes
Keep the Animal Poisons Helpline number (1300 869 738) in your phone before you need it. After hours emergency clinics fill quickly on weekends and holidays, so call ahead while you travel when advised. Hot weather makes dehydrated, vomiting pets deteriorate faster; use air-conditioned transport when you can and do not delay because the day feels busy.
Write a short card with your pet's weight, usual diet, and any chronic medicines. Hand it to triage nurses so details are not lost in the rush. Ask what home observations matter most in the first 24 hours after discharge.
If cost is a concern, say so early. Teams can often stage diagnostics while still covering the urgent risks. Avoid stacking random over-the-counter human products into the plan; they muddy the picture and can cause harm.
Extra context for worried owners
Write down a timeline while details are fresh: when the exposure happened, what was left on the floor, and which pets share the house. That scrap of notes helps Helpline staff and triage nurses more than a stressed verbal guess. If multiple pets had access, mention every animal, even the ones that "probably" did not eat anything.
Photograph packaging, plants, or broken objects before you bin them. Clear labels beat memory after a sleepless night. If you are driving to an emergency clinic, call ahead so the team can prepare; say whether your pet is vomiting in the car, seizuring, or having trouble breathing.
Do not crowd the pet with loud voices or forced exercise "to keep them awake" unless a clinician asks for that. Quiet transport, a non-slip surface, and a second person to watch breathing are enough for most trips. Keep a portable bowl of water available only if your vet said drinking is still appropriate.
During recovery at home, follow the feeding and recheck plan you were given. Soft stools for a day can be ordinary after gut stress; repeated vomiting, black stools, pale gums, collapse, or new tremors are reasons to call back the same day. Avoid adding new supplements, bone broths from oniony stock, or leftover human medicines while you wait for the all-clear.
Australian summers make dehydration and heat stress stack onto toxin cases. Park in shade, use air-conditioning if you have it, and do not leave animals in cars while you queue for reception. If bushfire smoke or extreme heat is also in the forecast, say so; clinics may adjust monitoring advice.
FAQ
My dog only sniffed smoke. Is that poisoning?
Brief second-hand exposure is usually less intense than eating edibles, but watch closely and call if wobbliness or urinary dribbling appears.
Should I make my dog vomit after a gummy?
Ask the Helpline or vet first. Timing, chocolate content, and sedation level change the answer.
Will my dog "just sleep it off" at home?
Mild cases are sometimes monitored, but only after professional triage. Concentrates and edibles often need clinic care.
Are CBD pet products automatically safe?
Quality and labelling vary; some products contain more THC than advertised. Only use products your veterinarian specifically recommends.
