What to Check Before Your Dog Swims Outdoors Safely

Not all dogs enjoy swimming or can even swim at all, but many dogs have a real affinity with the water. This is a typical characteristic of breeds such as the Labrador Retriever and the Newfoundland, known for their swimming skills and love of water.

Swimming is a fantastic form of low-impact exercise for your dog, but allowing them to swim in a new outdoor location should be done with care and planning. In this guide, we will cover the essential safety checks and precautions UK dog owners should take before letting their dogs swim outdoors in 2025.

1. Supervise Your Dog Closely

Always keep your dog under close supervision when swimming, even in shallow or calm waters, as accidents can happen quickly. Being alert and nearby can prevent many mishaps.

2. Assess Water Cleanliness and Quality

Visual inspection is helpful but can be misleading. Avoid water visibly polluted or with unpleasant odours. Check for signs of blue-green algae or harmful algal blooms, which are toxic to dogs. Consult local reports or advisories regarding water safety before your visit.

Be cautious of pesticides or chemical runoffs from nearby fields potentially contaminating the water. If plants, fish, and other wildlife are absent from the water, this suggests poor water health. Conversely, presence of wildlife drinking or inhabiting the area indicates cleaner water.

3. Ensure Your Dog’s Vaccinations Are Up to Date

Keep your dog's leptospirosis vaccination current, as the bacteria that causes this disease can be present in natural water sources. This vaccine plays a critical role in protecting your dog from serious infections transmitted through water exposure.

4. Check Water Temperature

Water is usually cooler than air temperature. Ensure water temperature is comfortable and safe for swimming to avoid hypothermia. When introducing your dog to a new spot, start in shallow, warmer parts before moving to deeper water.

5. Avoid Strong Currents and Undertows

Even gentle-looking currents or undertows can be dangerous for dogs. Only choose calm, still waters like lakes or sheltered beaches for swimming, unless you have verified safety through other experienced dog owners.

6. Verify Easy Access for Entry and Exit

Plan carefully how your dog will get into and out of the water. Dogs typically return to the point of entry to exit, so use the same spot for both to prevent panic and exhaustion. Check for obstacles such as sharp rocks, thick vegetation, or man-made barriers that might hinder exit.

7. Inspect for Underwater Hazards

Hidden dangers like sharp branches, fishing hooks, litter, shopping trolleys, and even barbed wire can injure your dog or trap them underwater. Walking the shore and shallow water with a careful check before allowing your dog in can prevent accidents.

8. Consider Seasonal Risks: Blue-Green Algae

Blue-green algae can bloom in warmer months and is highly toxic to dogs. Stay informed via local environmental warnings or websites on safe swimming locations, and never let your dog swim if algae is present.

9. Manage Crowds and Other Dogs

While seeing other dogs in a swimming spot is a good sign, overcrowding can lead to stress, aggressive interactions, or difficulties in exiting the water. Visit at quieter times for a more relaxed experience.

10. Use Suitable Toys and Maintain Safety in the Water

If you bring toys for water play, ensure they float and are safe. Avoid sticks, which can cause injuries, and in crowded spots, keep toys away to prevent resource guarding issues.

11. Watch for Wildlife Hazards

Be aware of local wildlife that could pose risks. For example, swans defending nests may become aggressive towards dogs, and jellyfish on beaches can sting. Do extra checks depending on your region and season.

12. Post-Swim Care

After swimming, rinse your dog with fresh water to remove contaminants like algae, salt, or sand. Check paws, ears, and skin for any injuries or irritation, and dry your dog thoroughly. This reduces the risk of infections and keeps your dog comfortable.

By following these steps, you ensure your dog’s swimming outings are safe and enjoyable. Taking time for careful planning promotes responsible ownership and protects your furry friend's health and happiness.
