Practical advice for safer, calmer autumn walks in Finchley and North London

Updated August 2026

Autumn is one of my favourite times of year for dog walking.

The temperature is often more comfortable than summer, local woods begin to change colour, and dogs can enjoy all the interesting smells among the fallen leaves.

However, autumn also changes how I plan and manage a walk.

The days become shorter. Paths become wetter. Leaves conceal broken glass, food and uneven ground. Acorns, conkers and fungi appear where dogs are sniffing. Ticks and harvest mites may still be active, and fireworks can begin well before 5 November.

The answer is not to stop enjoying autumn walks.

It is to slow down, look ahead and adapt the route to the individual dog.

This guide covers the autumn dog-walking hazards I watch for around Finchley, Muswell Hill and nearby North London areas.

For advice covering the complete year, visit Seasonal Pet Safety in Finchley.

Summary

Autumn can provide excellent walking weather, but shorter days and wetter conditions require extra planning.
Fallen leaves may conceal glass, food, dog mess, holes and uneven ground.
Conkers, acorns and unidentified fungi should not be eaten or used as dog toys.
Ticks and harvest mites can remain active during mild autumn weather.
Fireworks may begin well before Bonfire Night, so consider earlier walks and secure equipment.
Adjust the route, pace and distance for puppies, senior dogs and nervous or reactive dogs.
Check your dog’s paws, coat, ears and equipment after woodland or muddy walks.
Contact your vet promptly after suspected poisoning or when your dog becomes unwell.

Autumn dog walking checklist

Before leaving home

Check the weather and sunset time.
Carry a charged phone.
Use secure, correctly fitted walking equipment.
Take a torch or light when you may return after dark.
Carry more than one waste bag.
Take water on longer or unexpectedly warm walks.
Check that your dog’s identification tag is readable.
Consider whether fireworks or storms are likely.
Choose a route suited to your dog’s confidence and mobility.

During the walk

Watch for acorns, conkers and fungi.
Keep your dog away from discarded food.
Avoid unknown puddles and stagnant water.
Look carefully at ground covered by wet leaves.
Keep your dog closer near roads and hidden hazards.
Avoid damaged trees during strong winds.
Do not throw sticks.
Change direction when an area looks unsafe.

After the walk

Dry your dog’s paws and coat.
Check between the toes.
Look for cuts, seeds, ticks and orange harvest mites.
Check for unusual licking or scratching.
Remove mud before your dog licks it from their coat.
Check the harness, collar and lead.
Monitor appetite, energy and toileting.
Contact your vet if your dog becomes unwell.

Darker mornings and evenings

By autumn, many normal walks begin or finish in poor light.

Reduced visibility makes it harder to see:

Broken glass.
Uneven paving.
Potholes.
Low branches.
Cyclists.
Dropped food.
Other dogs.
People approaching from behind.
Acorns and conkers.
Objects hidden beneath leaves.

I prefer familiar routes when walking after dark, particularly with a nervous, reactive or older dog.

A torch helps me inspect the pavement and grass ahead instead of relying entirely on street lighting.

Reflective or illuminated accessories can make you and your dog easier to see, but they do not replace secure equipment, attentive handling or sensible road positioning.

Read Tips for Walking Your Dog at Night for more advice about visibility, equipment and choosing an appropriate route.

Check your dog’s identification

Autumn can bring fireworks, storms and unexpected noises that cause a dog to bolt.

Make sure:

The microchip record is current.
The collar fits securely.
The identification tag is readable.
The tag shows the owner’s name and address.
A telephone number is included.
The lead, harness and clips remain in good condition.

A microchip does not replace the legal requirement for a dog to wear a collar and identification tag in public.

You can check the current requirements through GOV.UK’s dog microchipping and identification guidance.

Keep your dog closer when you cannot see the ground clearly. Do not allow them to charge through a deep pile of leaves beside a road, bin or park bench.

Wet leaves can conceal hazards

A layer of autumn leaves can make an ordinary pavement or woodland path look harmless.

Underneath, there may be:

Broken glass.
Sharp metal.
Chicken bones.
Food waste.
Dog faeces.
Holes.
Uneven paving.
Slippery mud.
Discarded nicotine products.
Thorns.
Damaged branches.

This is one reason I slow down rather than allowing a dog to rush into every pile of leaves.

Keep your dog closer when you cannot see the surface. If an area beside a bench, bin or takeaway is covered with litter, move around it rather than hoping there is nothing harmful underneath.

Broken glass and paw injuries

Glass is particularly difficult to see under leaves or in poor light.

A dog who steps on glass may:

Yelp.
Limp.
Hold up a paw.
Refuse to bear weight.
Lick the paw repeatedly.
Leave bloody marks.

Move your dog away from the remaining glass and encourage them to stay still.

Do not probe the wound or pull out deeply embedded glass. Removing an embedded object can sometimes cause further bleeding or tissue damage.

My Dog Health and First Aid Guide explains how first aid supports a dog while professional veterinary help is arranged.

Slippery paths and mud

Wet leaves, algae, mud and poorly drained surfaces can become extremely slippery.

This matters particularly for:

Senior dogs.
Dogs with arthritis.
Dogs recovering from injury.
Dogs with reduced vision.
Puppies with limited coordination.
Dogs who pull strongly.
Owners with reduced mobility.

Slow down before:

Steps.
Slopes.
Wooden bridges.
Metal surfaces.
Wet paving.
Steep woodland paths.

A shorter, steadier walk is often more useful than pushing through a route where the dog or handler risks falling.

Mud itself is not always dangerous, but it can conceal sharp objects and hold material that your dog later licks from their coat.

After a muddy walk:

Wipe or rinse the paws.
Dry carefully between the toes.
Check for cuts.
Check the nails.
Remove plant material.
Inspect the belly and lower legs.
Wash and dry equipment where necessary.

Do not leave a wet, muddy dog for a prolonged period, particularly if they are elderly, very young, thin-coated or unwell.

Are conkers dangerous to dogs?

Conkers are commonly found beneath horse chestnut trees during autumn.

Do not encourage your dog to:

Catch them.
Chase them.
Carry them.
Chew them.
Use them as balls.

Conkers contain aesculin and can cause illness when chewed or swallowed. Their size and shape may also cause choking or an obstruction in the digestive system.

Possible signs can include:

Vomiting.
Diarrhoea.
Abdominal discomfort.
Restlessness.
Drooling.
Weakness.
Wobbliness.
Tremors.
Collapse.

Severe cases are uncommon, but you should contact your vet immediately if you believe your dog has eaten a conker. Do not wait for symptoms to appear.

The Blue Cross conker guide provides further veterinary-approved information.

Keep children’s conker collections somewhere your dog cannot reach.

Are acorns dangerous to dogs?

Acorns are not suitable toys or dog treats.

They contain tannins and may cause:

Vomiting.
Diarrhoea.
Abdominal pain.
Reduced appetite.
Lethargy.
Digestive obstruction.

Their hard or pointed shape can create an additional physical risk, particularly for a smaller dog.

Avoid throwing acorns or repeatedly allowing your dog to carry them. Contact your vet after suspected ingestion, even if your dog appears well.

You can read the Blue Cross advice about acorns and dogs.

For a complete comparison of the two hazards, read Are Conkers and Acorns Poisonous to Dogs?.

Teaching a leave or exchange cue

A reward-based leave or exchange cue can help when your dog notices an acorn, conker or discarded food.

Begin with safe, low-value objects at home.

Reward your dog for:

Moving away.
Looking back at you.
Releasing an item.
Following you away from the hazard.

Do not repeatedly chase, shout or grab at your dog. That can encourage some dogs to swallow an item quickly or begin guarding what they find.

If your dog already has something and you can safely exchange it, use an appropriate high-value reward.

Do not put your hand inside the mouth of a dog who is growling, freezing or likely to bite.

My Dog Training Hub contains more reward-based everyday training guidance.

Mushrooms and fungi

Damp autumn weather encourages fungi to appear in gardens, parks and woodland.

Some mushrooms cause digestive irritation. Others may affect the:

Liver.
Kidneys.
Nervous system.
Heart.

Identifying wild fungi from appearance alone can be extremely difficult.

The safest approach is to prevent your dog from eating unidentified mushrooms or toadstools.

If your dog eats a mushroom:

Move them away from the area.
Prevent them from eating more.
Photograph the mushroom and its surroundings where it is safe to do so.
Contact your vet immediately.
Follow the veterinary team’s instructions.

Do not wait for vomiting or other symptoms to begin.

Do not try to make your dog sick unless a veterinary professional specifically instructs you to do so.

PDSA’s guide to poisonous plants includes advice about autumn fungi and other seasonal plant risks.

Fallen fruit and berries

Autumn may bring fallen fruit beneath trees and into gardens.

Avoid allowing dogs to eat:

Mouldy fruit.
Large fruit stones or pips.
Grapes.
Unknown berries.
Fermenting fruit.
Fruit mixed with garden or food waste.

Fermenting fruit may contain alcohol, while mouldy material can contain dangerous toxins.

Fruit stones can also cause choking or an intestinal obstruction.

If the fruit cannot be identified or your dog has eaten a significant quantity, contact your veterinary practice.

Discarded food and Halloween treats

Autumn walks around schools, parks, takeaways and public events may involve dropped:

Chips.
Crisps.
Chocolate.
Sweets.
Chicken bones.
Takeaway containers.
Sauces.
Chewing gum.
Halloween treats.

Chocolate, grapes, raisins, onions, garlic and xylitol can all cause serious illness in dogs.

Do not assume food is safe because it looks familiar. It may contain toxic ingredients, mould, seasoning or packaging.

Halloween can create additional risks through:

Treat bowls.
Sweet wrappers.
Batteries.
Decorations.
Repeated doorbell activity.
Costumes.
Excited visitors.
People approaching in unfamiliar clothing.

Keep sweets and decorations away from your dog.

Do not force your dog to wear a costume for a photograph. Freezing, turning away, lip-licking, lowering the body, pawing at the clothing or trying to hide may indicate that your dog is uncomfortable.

Provide a quiet space away from the front door when visitors make your dog anxious.

Puddles and stagnant water

Puddles may contain:

Mud.
Bacteria.
Oil.
Road residue.
Garden chemicals.
Antifreeze.
Contaminated run-off.

Avoid allowing your dog to drink from unknown puddles, particularly near:

Roads.
Garages.
Car parks.
Industrial areas.
Driveways.

Carry clean water on longer walks and offer it before your dog begins searching for another source.

Clear water is not automatically safe water.

Blue-green algae in early autumn

Blue-green algae is usually associated with summer, but unsafe blooms may remain during warmer periods in early autumn.

Avoid water showing:

Green or blue-green scum.
Surface streaks.
Clumps.
Unusual discolouration.
Warning signs.

Do not allow your dog to swim in or drink from affected water.

Contact an emergency vet immediately after possible exposure. Do not wait for symptoms because blue-green algae poisoning can progress very quickly.

For wider advice about ponds, lakes and rivers, read Dog Swimming and Water Safety.

Harvest mites

Harvest mites are tiny orange mites commonly found in soil, grass and woodland.

They are most active from late summer into autumn and often affect the:

Feet.
Spaces between the toes.
Legs.
Armpits.
Belly.
Ears.

Possible signs include:

Intense itching.
Repeated licking.
Red or inflamed skin.
Small orange or red dots.
Scabs.
Broken skin.

Contact your vet if you suspect harvest mites. Your dog may require treatment, particularly when scratching has damaged the skin.

The PDSA harvest mite guide also explains their possible association with seasonal canine illness.

Seasonal canine illness

Seasonal canine illness is a rare but potentially serious condition associated with autumn woodland walks.

The cause remains uncertain.

Possible signs include:

Vomiting.
Diarrhoea.
Low energy.
Raised temperature.
Muscle tremors.

Symptoms may develop within a few days of a woodland walk.

Contact your vet immediately when these symptoms appear after recent woodland exposure. Do not assume vomiting after a walk is simply a mild stomach upset.

Tell your vet:

Where you walked.
When the walk took place.
When the symptoms began.
Whether harvest mites were noticed.
What your dog may have eaten.
Whether other dogs are affected.

Ticks do not disappear in autumn

Ticks can remain active in mild conditions and may be found in:

Long grass.
Woodland.
Areas used by deer.
Heathland.
Dense vegetation.

Check your dog after walks, particularly around the:

Ears.
Face.
Neck.
Armpits.
Belly.
Groin.
Spaces between the toes.

Ticks should be removed promptly and correctly with a suitable tick-removal tool.

Do not:

Burn the tick.
Cover it with petroleum jelly.
Squeeze its body.
Pull it sharply.
Try to drown it during a bath.

PDSA explains how to remove a tick safely.

Contact your vet if part of the tick remains, the skin becomes inflamed or your dog becomes unwell.

My Fleas and Ticks on Dogs guide provides further information about checking, prevention and treatment.

Fireworks can begin before November

Fireworks do not occur only on 5 November.

Private events and celebrations may begin earlier and continue for several weeks.

A dog who appears comfortable with distant bangs may still panic when a firework is unexpectedly set off nearby.

During likely fireworks periods:

Walk earlier where practical.
Keep your dog on a secure lead.
Avoid leaving them alone in the garden.
Check the collar, harness and lead.
Close windows and curtains.
Prepare a familiar resting or hiding place.
Keep water available.
Use familiar background sound.
Allow your dog to seek reassurance or hide.
Speak to your vet well before the season if fear is severe.

When fireworks are already sounding, a brief, secure toilet break and indoor enrichment may be safer than a normal evening walk.

Do not drag a frightened dog outside or let them off the lead because the park appears quiet.

Read Dogs and Fireworks: The Complete UK Safety Guide before the busiest part of the season begins.

Storms, strong winds and sudden weather changes

Autumn can bring:

Heavy rain.
Thunder.
Lightning.
Strong winds.
Local flooding.
Falling branches.
Damaged fencing.

Check the Met Office weather forecast before leaving.

During strong winds, avoid:

Woodland.
Mature trees.
Scaffolding.
Unstable fencing.
Exposed routes.
Areas with visible fallen branches.

After a storm, check your garden before allowing your dog outside.

My Extreme Weather Policy explains why I may shorten, move, adapt or cancel a walk when conditions become unsafe.

Sticks and fallen branches

Autumn storms leave more branches and sticks on the ground.

Do not throw sticks for your dog.

Sticks can:

Splinter.
Cut the tongue or gums.
Become wedged across the mouth.
Penetrate the throat.
Injure the chest.
Break into swallowed pieces.

Use a suitable dog toy instead.

Do not allow your dog to chew branches from unknown trees. The wood, plant species, mould or chemicals may create additional risks.

Read Sticks and the Dangers to Dogs for more information.

Wildlife

Autumn walks may bring dogs closer to:

Squirrels.
Foxes.
Deer.
Birds.
Badgers.
Other wildlife.

Keep your dog under control and prevent chasing.

The sensible approach is to:

Give wildlife space.
Avoid dens and resting places.
Keep your dog on the lead when recall is unreliable.
Follow local signs and restrictions.
Avoid approaching an injured or trapped animal.
Contact an appropriate wildlife organisation if help is needed.

Wildlife should be respected, but ordinary sightings do not need to turn a walk into a frightening experience.

Senior dogs in autumn

Cooler, wetter weather may affect a senior dog’s comfort and mobility.

Watch for:

Slower movement.
Stiffness.
Reluctance to leave home.
Difficulty on slippery ground.
Tiring more quickly.
Hesitation on steps.
Increased licking around joints.
Changes in posture.

Do not force a long walk because your dog managed that distance in the past.

A senior dog may benefit from:

A shorter route.
A slower pace.
More sniffing time.
Several brief walks.
Flatter surfaces.
Additional indoor enrichment.
Veterinary assessment of new or worsening discomfort.

Do not give herbal remedies or joint supplements without discussing them with your vet. Products may interact with medicines or be unsuitable for an individual dog.

Puppies and their first autumn

Autumn gives puppies many unfamiliar experiences:

Leaves.
Mud.
Umbrellas.
Dark streets.
Fireworks.
People wearing costumes.
Wet surfaces.
Wildlife.
New smells.

Introduce these gradually.

Do not overwhelm a puppy by taking them to a fireworks event, a crowded Halloween gathering, or a very long woodland walk.

Use calm, reward-based exposure and allow plenty of time for sleep and recovery.

Watch closely for puppies trying to swallow leaves, acorns, conkers, stones or litter.

Nervous and rescue dogs

Autumn can be challenging for dogs who rely on predictability.

Their normal route may suddenly involve:

Darkness.
Fireworks.
Strong wind.
People wearing hoods.
Umbrellas.
Children in costumes.
Slippery paths.
Busier daylight walking times.

Adapt the walk rather than forcing your dog through situations they cannot manage.

You may need to:

Walk earlier.
Choose a quieter street.
Reduce the distance.
Avoid busy park entrances.
Keep your dog on a lead.
Allow more sniffing.
Use suitable indoor enrichment.
Return home before your dog becomes overwhelmed.

My Rescue Dog Support in Finchley focuses on calm, low-pressure care for nervous, reactive and newly rehomed dogs.

Check your dog after every autumn walk

After an autumn walk, check the:

Paw pads.
Spaces between the toes.
Nails.
Lower legs.
Belly.
Armpits.
Ears.
Face.
Collar and harness areas.

Look for:

Cuts.
Swelling.
Seeds.
Ticks.
Orange harvest mites.
Mud.
Thorns.
Broken nails.
Red skin.
Unusual licking.

Also monitor:

Appetite.
Drinking.
Energy.
Vomiting.
Diarrhoea.
Lameness.
Behaviour changes.

My Post-Walk Dog Check Guide provides a complete step-by-step routine.

What to carry on an autumn dog walk

A practical autumn walking kit may include:

A fixed-length lead.
A secure harness or collar.
Waste bags.
A torch.
A charged phone.
Water.
A portable bowl.
A clean towel.
Sterile gauze.
Simple first-aid supplies.
Veterinary contact details.
Familiar rewards.
A tick-removal tool.

A Halti double-ended lead is one adjustable fixed-lead option for dogs who are comfortable using appropriate harness attachment points.

A foldable water bowl can be useful on longer walks or unexpectedly warm autumn days.

Choose equipment suitable for your dog’s size, health and handling needs. Check products regularly for wear and replace damaged clips, stitching or straps.

For more leads, harnesses, first-aid items and walking accessories, visit Dog and Pet Products I Recommend.

How I adapt autumn walks

My dog walks are one-to-one and begin and end at the client’s home.

I do not collect groups of dogs in a car or van.

This allows me to adapt each walk around:

Light levels.
Weather.
Fallen branches.
Fireworks.
Slippery routes.
Litter.
The dog’s age.
Mobility.
Confidence.
Scavenging.
Current health.

I may:

Change direction.
Use a quieter street.
Avoid woodland.
Keep the dog closer.
Reduce the distance.
Provide a toilet break and suitable indoor enrichment.
Return home early when conditions become unsafe.

The aim is not to complete a route at all costs.

It is to give the individual dog a safe, suitable and enjoyable experience.

Frequently asked questions

Are conkers poisonous to dogs?

Conkers contain aesculin and may cause illness when chewed or swallowed. They can also create a choking or blockage risk. Contact your vet immediately after suspected ingestion.

Are acorns poisonous to dogs?

Acorns contain tannins and may cause digestive illness. Their hard shape can also cause injury or obstruction. Contact your vet if your dog eats an acorn.

Can dogs play with conkers?

No. Do not throw conkers or use them as balls. Their size, hardness and toxicity make them unsuitable toys.

What should I do if my dog eats a mushroom?

Move your dog away, prevent further eating, photograph the mushroom safely and contact your vet immediately. Do not wait for symptoms or attempt to make your dog vomit.

Are harvest mites active in autumn?

Yes. They are commonly active from late summer into autumn and may cause intensely itchy, inflamed skin.

Do ticks disappear in autumn?

Not necessarily. Ticks can remain active during mild weather, particularly in long grass and woodland. Check your dog carefully after walking.

Should dogs drink from puddles?

It is safer to offer clean water. Puddles may contain bacteria, chemicals, oil, road residue, antifreeze or contaminated run-off.

Are wet leaves dangerous?

Leaves can become slippery and may conceal glass, food, holes and other hazards. Slow down and keep your dog closer when the ground is not visible.

Should I walk my dog during fireworks?

Walk earlier where practical. When fireworks are already sounding, a brief, secure toilet break and indoor enrichment may be safer than a normal evening walk.

Should I comfort a frightened dog?

Yes, if your dog seeks reassurance. Remain calm, allow them to hide when they choose and do not punish fearful behaviour.

Can I throw sticks for my dog?

No. Sticks can cause serious mouth, throat and internal injuries. Use a suitable dog toy instead.

When should I contact a vet after an autumn walk?

Contact your vet if your dog:

Eats a conker, acorn, mushroom or toxic food.
May have drunk contaminated water.
Develops vomiting or diarrhoea.
Becomes unusually tired.
Develops tremors.
Has a painful paw.
Cannot bear weight.
Has severe itching.
Develops breathing difficulties.
Collapses.

Autumn walks should remain enjoyable

Autumn does not need to become a list of reasons to stay at home.

It can be a lovely season for cooler walks, interesting smells and quiet exploration around Finchley, Muswell Hill and nearby North London areas.

The most useful changes are practical:

Walk before it becomes too dark where possible.
Watch what may be hidden beneath fallen leaves.
Prevent your dog from eating conkers, acorns and unidentified fungi.
Check for harvest mites and ticks.
Prepare before fireworks begin.
Change the route during storms or strong winds.
Check your dog carefully after the walk.
Contact your vet promptly if your dog eats something potentially harmful or becomes unwell.

A shorter, safer walk is better than continuing simply because you feel you must complete the usual distance.
