Snake Bite in Dogs: Signs and What to Do

Why is a snake bite so dangerous for a dog?

The RSPCA says dogs and cats are the domestic animals that most often need vet treatment for venomous snake bite, and that tiger and brown snakes cause most of those bites. Red-bellied black snakes, death adders and taipans are also a serious risk, and the species vary a lot between regions.

Venom from tiger and brown snakes commonly causes paralysis or muscle weakness and stops the blood clotting properly, which can lead to prolonged or heavy bleeding. Whether a bitten dog gets sick, and how badly, depends on the snake, how much venom it injected and where it bit. That is why the RSPCA says to treat every suspected bite as an emergency, whatever the snake, and why even a bite from a non-venomous snake can need a vet.

LocalPetFinder is an adoption listings site, not a vet. Everything here comes from the RSPCA, state and territory governments and published Australian veterinary research, read in November 2026. It is general information, not veterinary advice.

What are the signs of a snake bite in a dog?

You often won't see the bite, so the RSPCA says to watch for these signs, which vary with the snake and the animal:

The first row is the one that catches owners out. A dog that collapses and then gets up and seems normal has not necessarily escaped: the RSPCA lists that pattern as a sign in itself. If your dog was outside, near long grass, a wood pile or water, and collapses, shakes or vomits, assume a snake until a vet says otherwise.

What first aid does the RSPCA recommend?

The RSPCA Knowledgebase sets out these steps. They buy time on the way to the vet; they are not a treatment.

• Keep your pet calm and quiet and take it to a vet immediately. The chances of recovery are much greater if your pet is treated early.
• Call ahead, so the vet knows you are coming, can give you advice and can prepare.
• If possible, apply a pressure bandage: a firm bandage above, over and below the bite site, if you know where it is.
• If the bite is on the face or neck and your pet wears a collar, remove it, to avoid problems if the area swells.
• Do NOT wash the wound or apply a tourniquet.
• Leave the snake alone. Don't try to catch or kill it, and don't touch it even if it appears dead. If it is safe, take a photo from a distance and tell your vet what type of snake it was, if you know.

You do not need to know the snake for your dog to be treated. The RSPCA says your vet can perform a test to work out which antivenom should be given if it is needed. In the SnakeMap registry described below, a venom detection kit was used in 28% of cases.

What does the research say about snake bites in pets?

The best Australian picture comes from SnakeMap, a national registry led from the University of Melbourne's veterinary hospital, where participating vet hospitals enter the snake bite cases they treat. Its first four years (1 July 2015 to 30 June 2019) covered 624 cases from 28 hospitals in 6 states and territories (Boller et al, 2020):

Two findings change how you protect a dog. Most bitten dogs were bitten at home, in their own yard, not on a bush walk. And the late afternoon was the busiest time. The survival figure is encouraging, but it describes pets that got to a vet and, in most cases, got antivenom. That is the whole argument for going straight away.

When are snakes most active?

The RSPCA puts it simply: as the weather warms up, snakes become more active, and pet owners need to be extra careful. State and territory governments publish their own local information. The ACT Government, for example, says snakes in the ACT are most active from October to March and that the eastern brown snake is the most common in ACT gardens. Tasmania has three land snakes, the tiger snake, lowland copperhead and white-lipped snake, and the Tasmanian Government says all three can inject venom and that low temperatures generally limit snake activity to the warmer months between October and March.

Check your own state, territory or council page for the local species and season, and treat any suspected bite as an emergency whatever the month.

How do I protect my dog from snakes at home and on walks?

Because most dogs in the registry were bitten in their own yard, the yard is where prevention pays off first. The RSPCA says snakes are drawn to food, water and quiet places to hide, and recommends:

• Keep the grass low.
• Clean up rubbish piles and clear away hiding spots such as wood piles and sheets of corrugated metal.
• Consider a snake-proof fence around all or part of the property if snakes are common where you live.
• On walks near bushland, especially near water in summer, keep your dog on a leash and avoid long grassy areas.

If you see a snake in the garden, the RSPCA says not to try to catch or kill it: walk away slowly, watch it from several metres away and keep your pets safely away, because it will usually move on in its own time. If it stays and you want it gone, call a licensed snake handler. Snakes are protected, and the RSPCA notes most people who get bitten are bitten trying to remove one. The late-afternoon peak in the registry is also a good reason to keep end-of-day garden time supervised in the warm months.

What about cats?

Cats are bitten too: they made up a third of the SnakeMap cases. In that registry, cats were far less likely than dogs to be bitten in the owner's yard (26% against 85%) and took longer to reach a vet, with a median of 95 minutes against 60 for dogs (Boller et al, 2020). A cat that roams may simply come home unwell, so the RSPCA's note that not eating is a sign especially in cats matters. Weakness, dilated pupils or bleeding in a cat that has been outside is a vet trip now.

The RSPCA says keeping cats indoors with access to a snake-proof outdoor enclosure is the best way to prevent snake encounters. Our adopting a cat guide covers indoor life and cat runs.

What happens at the vet, and what does it cost?

The vet may test to identify the venom, and the RSPCA says a bitten pet may need antivenom plus other life-saving care: oxygen or a breathing machine, blood transfusions and intensive care. In the SnakeMap registry the median hospital stay was 25 hours.

There is no standard price; vets set their own fees and the bill depends on what the pet needs. The RSPCA warns plainly that snake bite treatment can mean a large vet bill, which is one more reason to put the effort into the yard. Ask for an estimate when you arrive, and see our cheap vet care guide for charity clinics, concession discounts and hardship funds.

Adopting a dog in snake country

None of this is a reason not to adopt. It is a reason to check the yard before the dog arrives. When you meet a rescue dog, ask the rescue what the dog is like off lead, since the RSPCA advises keeping dogs on a leash near bushland anyway. The RSPCA's Adopt A Pet site says its dogs and cats are desexed, microchipped and vaccinated; ask any other rescue what is included. For snakes, the protection the RSPCA describes is the yard, the lead and getting to a vet fast.

Our adopting a dog guide covers the first weeks, and crate training a puppy helps if you need to keep a young dog safe while you are busy. Use the adoption readiness check if you are still deciding.
