Water Safety for Dogs on Holiday: Lakes, Rivers and the Sea

For many dogs, a holiday isn't complete without a splash. Whether it's a paddle in a mountain stream, a swim in a Lake District tarn or a dash into the waves on a Cornish beach, water is one of the great joys of a dog-friendly break.

But unfamiliar water brings risks that you might not think about at home. Hidden currents, cold water and toxic algae can all catch out even confident swimmers. Here's how to keep your dog safe while they make the most of it.

Beware of Blue-Green Algae

Blue-green algae is the biggest hidden danger for dogs around lakes, ponds, reservoirs and slow-moving rivers. Some types produce toxins that can make dogs seriously ill very quickly, and it can be fatal. Dogs are at risk from swimming in it, drinking the water, or licking it off their coat afterwards.

It's most common in warm, still weather during late summer, but it can appear at any time of year.

How to spot it:

• Water that looks green, blue-green or brownish, or like pea soup or spilled paint
• Scum, foam or a film on the surface, especially around the edges
• Warning signs posted by the landowner or local council

Signs your dog may be affected include vomiting, diarrhoea, drooling, weakness, breathing difficulties, wobbliness or seizures. Symptoms can start within minutes or hours. If you think your dog has been in contact with blue-green algae, rinse them with clean water and contact a vet straight away. This is one of the reasons it's worth noting the nearest vet when you arrive at your cottage.

Rivers, Lakes and the Sea

Even strong swimmers can get into difficulty in unfamiliar water. Keep these risks in mind:

• Currents. Rivers can flow much faster than they look, especially after rain. At the beach, rip currents can pull a dog out to sea. Stick to calm, shallow spots where your dog can get out easily.
• Tides. Check tide times before heading to the beach. Incoming tides can cut off coves and sandbanks surprisingly quickly.
• Cold water. UK lakes, rivers and seas stay cold even in summer, and deep water can be much colder below the surface. Cold can tire a dog quickly, so keep swims short, especially for small, older or short-coated dogs.
• Steep banks. Check your dog can climb out. Steep or muddy banks, harbour walls and reservoir edges can leave a tired dog stranded.
• Hidden hazards. Rocks, weeds, fishing line and broken glass can all lurk under the surface.

Safe Swimming Habits

Not every dog is a natural swimmer. Breeds with short legs, heavy chests or flat faces, such as Bulldogs, Pugs, Dachshunds and Basset Hounds, can tire quickly and struggle in water. Puppies, older dogs and dogs with health conditions also need extra care.

Consider a dog life jacket if you're going on a boat, kayak or paddleboard, if your dog isn't a confident swimmer, or if you're near deep or moving water. Choose one with a grab handle on the back so you can lift your dog out, and let them get used to wearing it at home first.

A few simple habits help too:

• Let your dog go in gradually rather than throwing toys into deep water
• Keep sessions short and watch for signs of tiredness
• Bring fresh water so your dog isn't tempted to drink from lakes, rivers or the sea
• Keep your dog on a lead near livestock, nesting birds or busy beaches
• Make sure their recall is reliable before letting them swim off-lead

After the Swim

A little aftercare keeps your dog comfortable and protects your holiday cottage too.

• Don't let them drink seawater. Drinking a lot of salt water can make dogs very poorly. Offer plenty of fresh water and take regular breaks from playing in the sea.
• Rinse off salt, sand and mud. Salt and sand can irritate skin and paws. Many dog-friendly cottages have an outdoor tap or a boot room, and a portable dog shower or a bottle of water in the car works well too.
• Dry their ears. Water trapped in the ears can lead to infections, especially in dogs with floppy ears. Gently dry them with a towel after every swim.
• Watch for limping or a limp tail. Lots of swimming can leave dogs stiff and sore, so build up gradually.
• Pack extra towels. Most cottage owners ask that dogs are dried before coming inside, and you'll want to keep sofas and beds clean.

Make a Splash on Your Next Break

With a little care, water can be one of the highlights of your dog's holiday. Check the water before they go in, keep swims short, and you'll both come home with happy memories (and a very sleepy dog).

This is general advice, not veterinary guidance. If you're worried about your dog's health, always contact your vet.
