- Blue-green algae blooms in warm stagnant water and can kill a dog within hours. If the water looks like pea soup or spilled paint, keep your dog out of it.
- Bulldogs, Pugs, Frenchies, Corgis and Greyhounds are poor swimmers by build. For them a life jacket is equipment, not an accessory.

Every Australian summer produces the same two conversations. The first is someone surprised their dog could not swim. The second is someone whose dog swam beautifully for twenty minutes, got tired, and then could not work out how to get out of the pool. Both are avoidable, and neither is about swimming ability.
Water is genuinely one of the best things about summer with a dog — it cools them without the heatstroke risk of a hot walk, it burns energy fast, and most dogs love it. The point of this guide is not to keep your dog out of the water. It is to remove the handful of things that turn a good afternoon into an emergency.
The Myth That All Dogs Can Swim
Dogs will paddle instinctively when they hit water. That is not the same as being able to swim, and it is definitely not the same as being able to stay afloat for more than a minute or two. Body shape decides the outcome, and several popular breeds are built badly for it.
Deep chest, short legs
- Examples
- Bulldog, French Bulldog, Corgi, Dachshund
- In the water
- Front-heavy, nose drops below the surface
Flat face (brachycephalic)
- Examples
- Pug, Bulldog, Boxer, Shih Tzu
- In the water
- Must tilt head up to breathe, tires fast
Low body fat, dense muscle
- Examples
- Greyhound, Whippet, Staffy
- In the water
- Poor buoyancy, sinks rather than floats
Built for water
- Examples
- Labrador, Golden Retriever, Poodle, Spaniels
- In the water
- Strong swimmers, still need an exit route
| Build | Examples | In the water |
|---|---|---|
| Deep chest, short legs | Bulldog, French Bulldog, Corgi, Dachshund | Front-heavy, nose drops below the surface |
| Flat face (brachycephalic) | Pug, Bulldog, Boxer, Shih Tzu | Must tilt head up to breathe, tires fast |
| Low body fat, dense muscle | Greyhound, Whippet, Staffy | Poor buoyancy, sinks rather than floats |
| Built for water | Labrador, Golden Retriever, Poodle, Spaniels | Strong swimmers, still need an exit route |
Backyard Pools: It Is About the Exit
This is the single most useful thing in this article. Dogs that get into trouble in home pools are very often competent swimmers. What happens is they fall or jump in, swim to the edge, and find a smooth coping they cannot climb. They then swim the perimeter looking for a way out, tire, and go under. A dog that knows where the steps are does not have this problem.
Teach the Pool Exit
- 1
Pick one exit and make it obvious
Steps, a ledge or a dog ramp. Mark it with something visually distinct your dog can spot from water level — a bright mat or a potted plant at that corner.
- 2
Put a life jacket on for training
It keeps the head clear while your dog is still working things out, which keeps the lesson calm instead of panicky.
- 3
Walk them to it from in the water
Get in with them. From the middle of the pool, guide them to the exit and let them climb out themselves. Do not lift them out.
- 4
Repeat from every corner
Start them from each side of the pool so they learn to find the exit from anywhere, not just from the spot you always begin at.
- 5
Test it cold
Weeks later, pop them in near the far end and watch. If they track straight to the steps, they have it. If they hesitate, run it again.
Non-Negotiable for Poor Swimmers
Outward Hound Granby Splash Life Jacket

- Sized by girth, XS to XL
Rivers, Dams and Still Water: Blue-Green Algae
Warm weather plus still, nutrient-rich water produces cyanobacteria blooms, and they turn up in farm dams, slow rivers, lakes and ornamental ponds across Australia every summer. Some blooms produce toxins that attack the liver or the nervous system, and dogs are especially exposed because they swim in it and then lick it off their coat.
Beaches: Salt, Stingers and Fresh Water
The beach hazard people underestimate is the water itself. Dogs that spend an afternoon chasing balls into the surf swallow a surprising volume of salt water, and that causes vomiting, diarrhoea and dehydration. In serious cases it produces salt toxicity, with tremors and disorientation. The fix is almost comically simple: bring fresh drinking water and offer it constantly, so they are not drinking the ocean out of thirst.
Swallowing salt water
- What to do
- Offer fresh water every 15 minutes, limit fetch-into-surf sessions
Rips and currents
- What to do
- Keep dogs in the shallows; a ball thrown too far pulls them into a rip
Jellyfish and stingers
- What to do
- Check local warnings, especially far north QLD and northern WA in summer
Hot sand
- What to do
- Same rule as pavement — test with your hand before letting them run
Fish hooks and glass
- What to do
- Check paws afterwards, carry a first aid kit
Sunburn
- What to do
- Pale dogs and thin-coated bellies burn; use dog-safe sunscreen
| Beach hazard | What to do |

Stops Salt Water Drinking
Zenify Dog Travel Water Bottle
The thing that prevents the most common beach problem. A dog with fresh water in front of it drinks far less sea water, which heads off the vomiting and dehydration that ruins the evening after a good beach day.
- One-handed, one-thumb dispensing
- Leak-proof silicone seal
- 350 ml and 550 ml sizes
- Light at 135 to 160 g
Made for Dogs
Petkin Doggy Sunmist (120 ml)
Dog-formulated sun protection for the spots that burn: the bridge of the nose, ear tips and thin-coated belly. Follow the label for application, and reapply after swimming. Do not swap in a human sunscreen containing zinc oxide, which is toxic to dogs if licked.
- Formulated for dogs, unlike human sunscreen
- Listing compares it to SPF 15 human sunscreens
- For nose, ear tips and thin-coated bellies
- Follow the label and reapply after swimming
Summer Water Safety Checklist
- Test whether my dog can actually swim, in shallow water first
- Teach the pool exit from all four sides
- Buy a life jacket if my dog is a poor-swimming breed
- Never leave my dog near water unsupervised
- Pack fresh drinking water for every beach trip
- Check dams and rivers for algae scum before letting them in
- Rinse salt and chlorine off after every swim
- Dry ears properly to prevent ear infections
- Check paws for cuts, hooks and glass afterwards
After the Swim
Two minutes of aftercare prevents the most common post-swim vet visit, which is an ear infection. Water trapped in a warm ear canal is close to an ideal bacterial incubator, and floppy-eared breeds are worst affected. Rinse the coat with fresh water to get salt or chlorine off, then dry the ears gently with a soft towel or cotton wool — never push anything down the canal.
Teach the exit, respect still water, bring fresh water to the beach, and never leave them to it unwatched. Those four habits cover nearly every water incident that ends badly, and none of them cost you a single minute of your dog enjoying the best part of an Australian summer.
Common questions
Can all dogs swim?
No. Dogs paddle instinctively but body shape decides whether they stay afloat. Deep-chested short-legged breeds like Bulldogs, French Bulldogs and Corgis are front-heavy, flat-faced breeds struggle to keep their nose clear, and lean muscular dogs like Greyhounds have poor buoyancy. Always test in shallow water first.
How do I stop my dog drowning in the pool?
Teach the exit, not just swimming. Most incidents involve dogs that can swim but cannot find a way out, so they circle the edge until they tire. Pick one obvious exit, get in the water with them, and guide them to it from every corner until they can find it unprompted.
Is blue-green algae dangerous to dogs in Australia?
Yes, and it can be fatal within hours. Blooms occur in warm still water — dams, lakes, slow rivers — and dogs are exposed both by swimming and by licking their coat afterwards. If the water looks like pea soup or has a blue-green scum, keep your dog out. There is no antidote, so speed to a vet matters.
Why does my dog get ear infections after swimming?
Water trapped in the ear canal creates a warm, moist environment where bacteria and yeast thrive, and floppy-eared breeds hold it in worst. Dry the outer ear gently after every swim and never push cotton buds into the canal. Persistent head shaking means a vet visit.
Can dogs drink sea water?
They should not. Swallowed salt water causes vomiting, diarrhoea and dehydration, and in larger amounts can lead to salt toxicity with tremors and disorientation. Most dogs drink it simply because they are thirsty, so offering fresh water every fifteen minutes largely solves the problem.
