If your dog falls through the ice on a frozen pond or lake, stay on the bank, call 999 and ask for help. Never go onto the ice or enter the water after your dog.
A winter walk can be lovely—a cold, crisp morning, familiar woodland paths and a dog happily investigating all those interesting smells.
But frozen ponds, lakes and canals are a danger that is easy to underestimate.
I’ve been walking dogs professionally around Finchley and North London since 2011, and one of the most important things I’ve learnt is that the weather can change an otherwise familiar walk.
A pond that was open water yesterday might have a thin layer of ice today. To a dog, particularly one that enjoys swimming or chasing a ball, it may not look dangerous at all.
This guide explains how to keep your dog safe around frozen water, what to do if an accident happens and why even a dog that gets out of icy water may need urgent veterinary care.

Key Takeaways
- Never allow your dog to walk or play on frozen ponds, lakes, canals or reservoirs.
- Keep your dog on a secure, manageable lead well away from the water’s edge.
- If your dog falls through ice, call 999 immediately. Never attempt to rescue them by going onto the ice or entering the water.
- If your dog returns to safety, gently dry them, keep them warm and arrange urgent veterinary assessment.
- Wet dogs can develop hypothermia, even if they initially appear alert.
- Change your walking route when ice, slippery ground or poor visibility creates unnecessary risks.
Why are frozen ponds dangerous for dogs?
A frozen pond can look surprisingly solid.
Snow may even cover the surface, making it hard to tell the difference between firm ground and water.
The problem is that ice thickness can vary considerably across the same pond or lake.
Some areas may be thinner because of moving water, changing temperatures, vegetation or other local conditions. Ice that appears thick around the edge may be much weaker further out.
A dog cannot judge whether the surface will support their weight.
And even a strong swimmer may struggle if the ice breaks beneath them.
Cold water can quickly affect a dog’s ability to move, while the surrounding ice may make it difficult to climb back onto solid ground.
This is why my approach is straightforward: if there is a risk of frozen water, I keep dogs away from it.
The London Fire Brigade’s winter water safety guidance also advises keeping dogs on leads near frozen water and staying away from the edge.
How to keep your dog safe near frozen ponds and lakes
Prevention is much safer than dealing with an emergency.
Keep your dog on a lead
If I’m walking anywhere near frozen water, I want the dog securely attached to me and well away from the edge.
I prefer a properly fitted harness, such as a perfect fit, a fixed-length lead, or a suitably shortened adjustable lead.
A long line that is useful in an open field is not necessarily suitable beside a frozen pond.
You need enough control to prevent your dog from reaching the water, not several metres of line that lets them build up speed towards it.
Do not throw toys onto frozen water
This includes balls, sticks and other toys.
Some dogs become so focused on retrieving an object that they pay little attention to the ground beneath them.
A ball landing on ice can invite a dog to run straight after it.
Even if your dog normally has excellent recall, I would not test it around a frozen pond.
Watch for hidden water
Snow can make familiar surroundings look completely different.
Be particularly careful around:
- Ponds and lakes
- Canals and reservoirs
- Frozen streams and ditches
- Flooded fields
- Water beneath snow-covered banks
Where visibility is poor, stick to familiar paths and give water an even wider berth.
Change the walking route.
I don’t think a dog has to complete a particular route simply because that is where they normally go.
If frost or ice makes somewhere unsuitable, I’ll choose somewhere else.
During winter walks around Finchley, I may use a shorter route, stay on safer paths or spend more time on calm sniffing activities rather than covering the usual distance.
My Winter Dog Walking Guide explains how I decide when to shorten, change or occasionally skip a normal walk.
What should you do if your dog falls through ice?
Seeing your dog fall into freezing water would be frightening.
Your instinct may be to rush towards them, but doing so could put both of you in danger.
The London Fire Brigade provides clear advice for incidents involving people or pets falling through ice.
1. Stay on safe ground
Do not walk onto the ice.
Do not wade or swim after your dog, even if they appear close to the bank.
Never assume the ice is strong enough to hold you because it briefly supported your dog.
Stay away from unstable or slippery edges.
2. Call 999 immediately
Tell the emergency operator that a dog has fallen through ice.
Give your location as accurately as possible, including the name of the park, pond or nearby landmarks.
Follow the instructions given by the emergency services.
If there are other people nearby, ask someone to help identify your exact location, but nobody should go onto the ice.
3. Encourage your dog back if you can do so safely
If your dog can hear you, try calling them calmly from a safe position.
Use a familiar recall cue.
Avoid frantic movements that might encourage your dog to move towards a more dangerous area.
Do not step onto the ice, lean over an unstable bank or try to smash the ice with branches or stones.
The priority is to avoid turning one emergency into two.
4. Let the emergency services manage the rescue
A dog may be frightened, exhausted or unable to find a safe way out.
Do not assume that being a good swimmer means your dog will escape without help.
Stay in a safe place, keep the emergency services informed and follow their instructions.
For official advice, read London Fire Brigade: Winter Water Safety.
What should you do once your dog is out of icy water?
If your dog gets back onto dry ground or is rescued, they may still be at serious risk from cold exposure.
Contact your vet or an emergency veterinary practice immediately and arrange an assessment, even if your dog initially seems reasonably well.
While arranging veterinary care:
- Move your dog into a safe, sheltered place.
- Gently towel-dry them if they are wet.
- Wrap them in dry blankets or towels, including underneath them where possible.
- Warm them gradually in a comfortable environment.
- Follow your vet’s advice about transport and any additional care.
Avoid direct heat from heaters, hot water bottles or other very hot objects, as these may cause burns or warm the dog too quickly.
Do not rub them with snow, leave them lying on frozen ground or assume a winter coat alone is enough.
The PDSA’s veterinary guidance on hypothermia in pets recommends gradual warming and veterinary assessment even when a pet appears to have recovered.
Can a dog get hypothermia after falling into a pond?
Yes.
Hypothermia occurs when the body’s temperature drops dangerously low.
Cold water can cause rapid heat loss, particularly when a dog remains wet and exposed to cold air afterwards.
Any dog can be affected, although some are more vulnerable, including:
- Puppies
- Older dogs
- Very small dogs
- Underweight dogs
- Dogs with health conditions
- Dogs that are already cold or exhausted
According to the PDSA, warning signs can include shivering, unusual drowsiness, confusion, clumsiness, pale gums and collapse.
A severely cold dog may stop shivering, so the absence of shivering does not mean everything is fine.
Hypothermia is a veterinary emergency.
If your dog has fallen into freezing water, seek veterinary help rather than waiting for obvious symptoms.
You can also find general emergency preparation advice in my Dog Health and First Aid Guide.
Can dogs swim safely in cold water?
Some dogs love swimming, but enthusiasm doesn’t necessarily mean they understand the dangers.
A dog that swims confidently in summer may struggle in very cold water, on difficult banks, in currents, or when exhausted.
Frozen water adds the danger of breaking ice and an obstructed escape route.
Even breeds commonly associated with swimming should be kept away from frozen ponds.
For advice about swimming when conditions are suitable, read my Dog Swimming and Water Safety Guide.
How I manage icy dog walks in Finchley.
Winter in North London is often more about cold rain, muddy paths and occasional frost than weeks of deep snow.
But it only takes one freezing morning to change the conditions.
Places such as Cherry Tree Wood, Coldfall Wood, Highgate Wood and the Parkland Walk can be lovely places for a dog to explore.
I still assess the conditions rather than assume a familiar route will always be suitable.
When the weather becomes icy, I consider:
- Whether the paths are slippery
- Whether water hazards can be avoided
- How secure the dog’s walking equipment is
- Whether the dog can move comfortably
- How easily I can change the route
- Whether a shorter walk would be more sensible
Because my dog walks are one-to-one and start from the client’s home, I can adapt the route to suit the individual dog and conditions.
That may mean a shorter local walk, a different path or some additional calm enrichment.

Does walking equipment make frozen water safer?
Good equipment helps you manage your dog, but it cannot make frozen water safe.
For winter walks, I prefer a comfortable, secure harness and a reliable fixed-length or adjustable lead.
I do not recommend retractable leads, particularly around roads, icy paths or water.
Where equipment needs replacing, my Dog Leads and Harnesses Guide explains what I recommend and why proper fit matters.
However, the most useful safety decision around frozen water costs nothing.
Keep your distance and choose a safer route.
Frequently asked questions
Is it safe for dogs to walk on frozen ponds?
No. Ice can vary in thickness and strength, and a dog cannot judge whether it will support their weight. Keep dogs on a lead and away from frozen water.
What if my dog runs onto a frozen pond but hasn’t fallen through?
Stay off the ice. If possible, call your dog back calmly from a safe position. If your dog is stranded or in immediate danger, call 999 and follow the emergency services’ instructions.
Should I take my dog to the vet after falling into icy water?
Yes. Contact your vet immediately and arrange an urgent assessment, even if your dog appears to have recovered. Cold-water exposure can result in hypothermia and other complications.
Can thick-coated dogs get hypothermia?
Yes. A thick coat does not provide complete protection, particularly when a dog becomes soaked in very cold water.
Should I let my dog off the lead near frozen water if they have good recall?
No. A familiar recall cue is useful, but it is not a substitute for preventing access to dangerous ice.
A safe winter walk is still a good walk
Most winter walks are perfectly manageable with a little preparation.
Your dog can still enjoy fresh air, sniffing, exploring and spending time with you.
The important thing is recognising when something has changed.
Frozen ponds are one of those hazards I would never take a chance with.
Keep your dog safely away from the ice. Choose another route if necessary.
And remember, there is nothing wrong with a shorter walk when conditions are unsafe.
Your dog won’t measure the success of their day by the distance you have covered.
