Open water poses serious risks for dogs, including drowning, injury, and illness, as UK campaigners warn pet owners about lakes, rivers, and coastal areas. With rising temperatures, more families are heading to scenic spots like Earlswood Lakes, but even strong swimmers can struggle in unpredictable conditions. This guide covers the hidden dangers and how to protect your furry friend.
Why Open Water Is Dangerous for Dogs
Unlike pools, open water has hidden currents, sudden drop-offs, and cold temperatures that can shock a dog's system. Even a confident swimmer like Bruno the dalmatian can tire quickly or get caught in a rip current. According to Dogs Trust, dog-related incidents in UK open water hit a five-year high in 2025, a 39% increase from the previous year.

Key Hazards in Lakes, Rivers, and Seas
- Drowning – Fatigue, strong currents, or inability to find an exit point.
- Injury – Submerged debris, sharp rocks, or boat propellers.
- Illness – Blue-green algae, bacteria, or parasites in stagnant water.
- Cold water shock – Even in summer, deep water can be freezing.
- Panic and exhaustion – Dogs can overestimate their stamina.

How to Keep Your Dog Safe Near Open Water
Emma-Jane Thomas, rehoming manager at Dogs Trust Kenilworth, advises: “If in doubt, keep your dog out.” Before letting your dog swim, assess the environment for warning signs, fast-moving water, or algae blooms. Always keep your dog on a lead near unfamiliar water, and never force a reluctant dog to enter.
Essential Safety Checklist
- Check for blue-green algae – toxic and often fatal.
- Use a dog life jacket for extra buoyancy.
- Keep your dog on a lead near steep banks or fast currents.
- Teach your dog a reliable recall command.
- Rinse your dog with fresh water after swimming.
What to Do in an Emergency
If your dog gets into trouble, do not jump in after them – you could drown too. Instead, call for help, use a throw line or long stick, and alert the coastguard or local rescue services. After any incident, seek veterinary attention even if your dog seems fine, as they may have swallowed water or toxins.
