Beach & Pool Safety: How to Keep Your Pet Safe During Water Play?

ImmunityQ&AMeongsiljang Veterinary Advisory Board

We’ve compiled safety guidelines and emergency response steps to help prevent drowning, waterborne infections, and heatstroke in pets at beaches and swimming pools.

What Is Beach & Pool Safety?

Beach and pool safety guidelines help prevent drowning, waterborne infections, heatstroke, and skin injuries in pets during water activities. The three most important measures are: having your pet wear a life jacket, taking a 30-minute rest break, and providing clean fresh water. Many dogs are poor swimmers, and cats generally dislike water and are highly susceptible to stress, which can easily cause anxiety in aquatic environments. Therefore, owners must closely supervise their pets and ensure an ample supply of clean fresh water is available.

Why Are Beaches & Pools Dangerous?

Pets are less efficient at regulating their body temperature than humans, and areas with sparse fur—such as around the nose, the belly, and the paw pads—are particularly vulnerable to ultraviolet radiation. At the beach, swallowing seawater can lead to salt poisoning and diarrhea, while in swimming pools, chlorine can irritate the eyes and skin. Brachycephalic breeds (such as Bulldogs, Pugs, and Persians) and small dogs tire quickly, placing them at a particularly high risk of drowning.

Main risk	Salt poisoning·drowning in waves	Chlorine conjunctivitis·dermatitis	Leptospira infection
If swallowed	Vomiting·diarrhea·seizures	Gastrointestinal irritation·vomiting	Bacterial enteritis

Essential Safety Gear to Bring

Life Jacket: Essential even for dogs who are strong swimmers, as waves and currents can quickly drain their energy.

Fresh Drinking Water: Dogs may be tempted to drink seawater or pool water when thirsty, so offer clean drinking water frequently.

Pet Sunscreen: Always apply pet-specific sunscreen to hairless areas like the nose, ears, and belly. Human sunscreen may contain harmful ingredients if licked, so choose products formulated for pets.

Shade Shelter: On hot days, prolonged exposure to direct sunlight can cause overheating and heatstroke, so ensure your dog rests in the shade regularly.

Emergency Signs Requiring Immediate Veterinary Care

If your pet shows any of the following symptoms after swimming, take them to a 24-hour veterinary clinic immediately: • Repeated vomiting and diarrhea (suspected ingestion of large amounts of seawater) • Persistent coughing or labored breathing (possible aspiration pneumonia due to inhalation of water or foreign objects) • Gums turning purple or dark blue (a sign of oxygen deprivation) • Staggering, collapse, or seizures • Increased respiratory rate and effort, accompanied by ongoing lethargy In particular, swallowing large amounts of water can lead to aspiration pneumonia, and symptoms may not appear immediately. Therefore, it is essential to closely monitor your pet’s coughing, respiratory rate, and energy levels for at least 48 hours after swimming.

Essential Post-Swim Care

Lukewarm full-body rinse: Thoroughly rinse off seawater, chlorine, and sand to prevent dermatitis.

Ear drying: Instead of cotton swabs, gently wipe the outer ear with a soft towel and clean the ear canal with a veterinarian-prescribed ear cleaner. Prolonged moisture can lead to otitis externa.

Paw inspection: Check for cuts from shell fragments or glass shards.

Hydration and temperature recovery: Let your pet rest in a cool indoor environment for at least one hour.

Can I Take My Cat to the Beach or Pool?

Many cats inherently dislike water and are highly sensitive to stress, so we generally do not recommend taking them to beaches or swimming pools. However, certain breeds that are more comfortable around water, such as Maine Coons and Bengals, may be briefly exposed to shallow bathtubs or restricted pools for no more than 10 minutes, provided they are wearing a harness and a life vest. Ingesting large amounts of chlorinated or seawater can cause gastrointestinal irritation or electrolyte imbalances, so always ensure your cat has plenty of fresh, clean drinking water available.

Additional Precautions by Breed

Brachycephalic breeds (Bulldogs, Pugs, Shih Tzus, Persians): Their shortened and narrowed nasal and airway structures make them prone to breathing difficulties due to Brachycephalic Airway Obstruction Syndrome (BAOS). Please avoid swimming altogether and limit water exposure to paw soaks only. Large breeds (Labradors, Retrievers): While they have good stamina, their body temperature can rise quickly during exercise. Be sure to let them rest in the shade after 30 minutes of swimming. Senior dogs and those with heart conditions: Avoid prolonged swimming without consulting your veterinarian. Thin-coated breeds (Italian Greyhounds, Sphynx): Their sparse coats make them vulnerable to UV rays, so please apply pet-safe sunscreen thoroughly.

Frequently Asked Questions

Is the chlorine in swimming pools harmful to the skin?

Standard chlorine levels in swimming pools are generally safe for short-term exposure. However, prolonged contact or exposure in pets with compromised skin barriers can lead to dryness and itching. After swimming, rinse your pet thoroughly with lukewarm water and apply a moisturizer.

My pet drank a little seawater. Is that okay?

While a small amount of saltwater ingestion usually resolves on its own, repeated vomiting, diarrhea, or lethargy may indicate excessive salt intake. Immediately offer small amounts of fresh, clean water, and seek veterinary care if symptoms persist.

Even if your dog is a good swimmer, a life jacket is still essential.

Yes, it’s essential. Drowning can happen to any dog, regardless of swimming ability, due to waves, sudden currents, or exhaustion. A life jacket is also important because its handle allows you to quickly pull your dog out of the water.

How many days should I observe my pet after swimming?

Monitor your pet’s respiratory rate, coughing, and appetite for at least 48 hours, ideally 72 hours. This is because aspiration pneumonia can develop later if water is aspirated into the lungs. If your pet’s breathing becomes faster or more labored than usual at rest, or if coughing persists, a veterinary visit is necessary.

Can puppies enjoy swimming too?

It’s safest to avoid beaches and public swimming pools until your puppy has completed all of its core vaccinations, since young dogs are more susceptible to infectious diseases. Even after they’re fully vaccinated, start with short sessions in shallow water, keeping them to 10–15 minutes at a time.
