Staying Safe Around Ponds and Rivers
Strolling by the River Thames, wandering Richmond Park, or walking through Ham Lands often means one thing for many dogs – the irresistible urge to jump in for a paddle. While most Labradors and water-loving breeds won’t think twice about diving in, owners need to be aware that not all water is safe.
Natural rivers, ponds, and lakes can pose serious – sometimes life-threatening – risks to dogs. These dangers aren’t always obvious, and some can also affect humans.
Can Dogs Get Sick from River or Pond Water?
Yes – and some illnesses can be devastating. While we don’t see these problems every day, when they do occur, they can be severe. Here’s what you need to know about the main hazards in Richmond’s waterways:
Leptospirosis – A Hidden but Serious Threat
Leptospirosis is a bacterial infection spread by rat urine, commonly found in rivers, canals, and stagnant water. Dogs can contract it by drinking contaminated water or even through small cuts in their skin.
Symptoms can include fever, lethargy, vomiting, and severe kidney or liver damage. Without prompt treatment, it can be fatal.
Leptospirosis isn’t just a danger to dogs – it can also infect humans, where it is known as Weil’s disease, a serious illness that can lead to hospitalisation.
The good news? Regular vaccination protects your dog. At The Vet on Richmond Hill, we now use Lepto 4 as our standard vaccine, which offers the most comprehensive protection. Keeping boosters up to date is essential, especially for dogs who enjoy outdoor swimming.
Blue-Green Algae – A Summer Killer
During warm weather, especially in still or slow-moving water, toxic blue-green algae can bloom. It’s been reported in areas such as Richmond Park and Wimbledon Common.
Dogs are particularly at risk as they may swallow water or lick algae off their fur. Even a small amount can cause vomiting, seizures, liver failure, and death within hours.
If the water looks green, has a surface scum, or smells unusual, keep your dog out completely. Warning signs are sometimes posted but not always.
Parasites and Bacteria – The Hidden Risks
Stagnant or slow-moving waters can harbour harmful organisms, including Giardia, E. coli, and Cryptosporidium, which can cause diarrhoea, dehydration, and weight loss.
Dogs often pick these up by taking just a few laps of pond water, so it’s safest to carry fresh water for your dog and discourage drinking from puddles, ponds, or rivers.
Drowning and Physical Hazards
While most dogs are strong swimmers, dangers remain:
- Fast-flowing rivers like parts of the Thames can catch dogs off guard.
- Steep or slippery banks can trap dogs who jump in and can’t climb out.
- Older dogs, puppies, and flat-faced breeds (like Bulldogs and Pugs) are more at risk of getting into trouble.
If your dog is near deep or moving water, keep them within reach, or on a lead.
How to Protect Your Dog
- Keep their Leptospirosis (Lepto 4) vaccinations up to date.
- Avoid stagnant or green-tinged water, especially in warm weather.
- Bring clean drinking water on walks so your dog isn’t tempted to lap from rivers or ponds.
- Be extra cautious near fast or deep water, especially with at-risk dogs.
- Watch for algae warning signs – and trust your instincts if the water doesn’t look right.
