Australia has some of the most venomous snakes in the world, and every spring and summer thousands of dogs are bitten, mostly by brown and tiger snakes. Treatment works well when it starts early. It is also one of the more expensive emergencies, mainly because of antivenom and intensive care.
Snake bite treatment for a dog in Australia averaged $1,121 in PetSure’s 2023 to 2024 claims data, with the most expensive dog claim at $24,754. Antivenom is commonly quoted at around $500 to $1,000 per vial, and some dogs need several. A dog that needs one or two vials and a night or two in hospital typically lands at $2,000 to $5,000. Dogs that need a ventilator can cost $10,000 to $25,000.
| Situation | Typical cost | What it includes |
|---|---|---|
| Checked and observed, no envenomation found | $300 to $900 | Consult, blood clotting tests, several hours of observation |
| Envenomated, 1 vial of antivenom | $1,500 to $3,000 | Antivenom, IV fluids, monitoring, 1 night in hospital |
| Envenomated, 2 or more vials | $3,000 to $6,000+ | More antivenom, longer stay, repeat blood tests |
| Paralysis needing a ventilator | $10,000 to $25,000 | Intensive care, mechanical ventilation for days |
| Average insurance claim, dogs (PetSure 2023 to 2024) | $1,121 | Includes simple and complex cases |
| Average insurance claim, cats (PetSure 2023 to 2024) | $987 | Highest cat claim $12,312 |

Why antivenom makes the bill so big
Antivenom is made by immunising animals against venom and purifying the antibodies, and it has a short shelf life, so clinics carry it at a real cost whether or not they use it. A dog with a large bite, or a small dog with a relatively larger dose of venom, may need more than one vial.
The bigger cost driver in severe cases is paralysis. If the venom affects the muscles used for breathing, a dog may need to be on a ventilator in intensive care for days. That is where claims reach $20,000 or more.
Signs your dog may have been bitten
- Sudden weakness or wobbliness, especially in the back legs
- Collapse, sometimes followed by an apparent recovery
- Vomiting, drooling or trembling
- Dilated pupils
- Blood in the urine or bleeding that will not stop
- Swelling or bite marks, though these are often hard to see
Many owners never see the snake. If your dog was barking at something in the garden or in long grass and then acts strangely, treat it as a possible bite.
Does pet insurance cover snake bites?
Snake bites are usually covered as an accident under accident-only and accident and illness policies, after your excess. Check the annual limit and any sub-limits: a ventilator case can exceed a $10,000 limit. Run the numbers on our pet insurance calculator.

Reducing the risk in snake season
- Keep dogs on a lead near bushland, creeks and long grass from spring to autumn.
- Keep grass short and clear woodpiles, rubbish and dense shrubs near the house.
- Know where your nearest 24-hour emergency vet is before you need it, especially when travelling.
- Do not let your dog chase or investigate snakes. Most bites happen when dogs try to kill them.
Common questions
How much does snake antivenom cost for a dog in Australia?
Antivenom is commonly quoted at around $500 to $1,000 per vial, and some dogs need more than one. The full bill, including hospital care, is usually $1,500 to $6,000, and much more if a ventilator is needed.
What is the average vet bill for a snake bite?
PetSure’s 2023 to 2024 claims data puts the average dog snake bite claim at $1,121 and the average cat claim at $987, with the most expensive dog claim at $24,754.
Can a dog survive a snake bite without antivenom?
Some dogs survive dry bites or small doses, but you cannot tell from looking. Untreated envenomation can be fatal, and treatment is far more successful when started early. Always go to a vet.
Is a snake bite covered by pet insurance?
Usually yes, as an accident, under both accident-only and accident and illness policies. Your excess, benefit percentage and annual limit still apply.
