Autumn Dog Walking Tips: Dark Evenings, Conkers, Fungi and Fireworks

ByDerek

Updated July 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 plenty of interesting smells among the fallen leaves.

However, autumn also changes the way 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. 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.

Autumn dog walking checklist

Before leaving home:

  • Check the weather and daylight
  • Carry a charged phone
  • Use secure, well-fitting walking equipment
  • Take a torch or light 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 fireworks or storm forecasts
  • 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
  • Check the ground beneath wet leaves
  • Use a shorter lead 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 paws and the 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
  • Monitor appetite, energy and toileting
  • Contact your vet when 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 under leaves

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

A torch helps me check the pavement and grass ahead rather than relying only 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 good road positioning.

Read Tips for Walking Your Dog at Night for the full night-walking guide.

Check your dog’s identification.

Autumn can bring fireworks, storms and sudden 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

Blue Cross recommends checking microchip details and identification before fireworks season because frightened dogs may try to escape.

Read Why Dogs Need Both a Microchip and Identification Tag.

Wet leaves can conceal hazards

A layer of leaves can make an ordinary pavement or 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

PDSA advises taking care around mud and leaves because sharp stones and rubbish can be hidden beneath them and injure a dog’s paws.

Keep your dog closer when you cannot see the surface clearly.

Do not allow them to charge through a deep pile of leaves beside a road, bin or park bench.

Slippery paths

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

This matters for:

  • Senior dogs
  • Dogs with arthritis
  • Dogs recovering from injury
  • Dogs with reduced vision
  • Puppies with little coordination
  • Dogs who pull
  • 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 both the dog and handler are at risk of falling.

Read How Weather Affects Dog Walks for broader weather planning.

Broken glass

Glass may be harder to see beneath 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
  • Leave bloody marks

Move away from the remaining glass and keep the dog still.

Do not probe a wound or pull out embedded glass.

Read My Dog Stepped on Broken Glass for paw first aid and signs that need urgent veterinary attention.

Conkers

Conkers are common 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 may cause poisoning when eaten. Their size and shape can also cause choking or a digestive blockage.

Possible signs include:

  • Vomiting
  • Diarrhoea
  • Abdominal discomfort
  • Restlessness
  • Weakness
  • Wobbliness
  • Tremors
  • Collapse

Blue Cross advises contacting your vet immediately when you think your dog has eaten a conker. (Blue Cross)

Do not wait for symptoms.

Keep children’s collections of conkers somewhere the dog cannot reach.

Acorns

Acorns are not suitable toys or dog treats.

They contain tannins and may cause:

  • Vomiting
  • Diarrhoea
  • Abdominal pain
  • Reduced appetite
  • Digestive blockage

The hard or pointed shape may create additional physical injury, particularly in a smaller dog.

Blue Cross advises contacting your vet straight away after suspected acorn ingestion. (Blue Cross)

Avoid throwing acorns for your dog or allowing them to carry them repeatedly.

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.

Practise initially with safe, low-value objects at home.

Reward your dog for:

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

Do not repeatedly chase, shout or grab at the dog.

That can encourage some dogs to swallow the item quickly or begin guarding what they find.

Where your dog already has the item, and you can safely exchange it, use a suitable high-value reward.

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

Mushrooms and fungi

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

Some mushrooms cause only digestive irritation. Others may affect:

  • The liver
  • Kidneys
  • Nervous system
  • Heart rhythm

Identifying fungi from appearance alone can be extremely difficult.

PDSA recommends preventing pets from eating unidentified fungi because some UK species can cause severe or fatal illness.

When your dog eats a mushroom:

  1. Move them away from the area.
  2. Prevent further eating.
  3. Photograph the mushroom and its surroundings where safe.
  4. Contact your vet immediately.
  5. Follow the veterinary team’s instructions.

Do not wait to see whether vomiting begins.

Do not attempt to make your dog sick.

Fallen fruit and berries

Autumn may bring fallen fruit beneath trees and in gardens.

Avoid allowing dogs to eat:

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

Fermenting fruit may contain alcohol, while mouldy material may contain harmful toxins.

Fruit stones may also cause choking or obstruction.

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

Discarded food

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 poisoning in dogs. Blue Cross advises contacting a vet immediately after suspected ingestion of a toxic food.

Do not assume that food is safe because it looks familiar.

It may contain seasoning, toxic ingredients, mould or packaging.

Halloween

Halloween creates additional risks through:

  • Chocolate
  • Sweets
  • Xylitol-containing products
  • Wrappers
  • Decorations
  • Batteries
  • Repeated doorbell activity
  • Costumes
  • Excited visitors
  • People approaching in unfamiliar clothing

Keep sweets and treat bowls away from your dog.

Do not force a dog to wear a costume for photographs.

Signs that a dog is uncomfortable may include:

  • Freezing
  • Turning away
  • Lip licking
  • Lowering the body
  • Pawing at the clothing
  • Hiding
  • Trying to remove it

A simple familiar collar or bandana is often enough for a dog who genuinely enjoys wearing one.

Provide a quiet space away from the 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.

Do not assume that clear water is automatically safe.

Blue-green algae can remain an early-autumn risk.

Blue-green algae is usually associated with warm weather, but unsafe blooms can remain present into early autumn.

Avoid water displaying:

  • 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.

PDSA warns that blue-green algae is highly toxic and can become fatal very quickly. (PDSA)

Contact an emergency vet immediately after suspected exposure.

Do not wait for symptoms.

Mud

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

After a muddy walk:

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

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

Harvest mites

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

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

  • Feet
  • Spaces between toes
  • Legs
  • Armpits
  • Belly
  • Ears

Possible signs include:

  • Intense itching
  • Repeated licking
  • Red skin
  • Inflamed patches
  • Orange or red dots
  • Scabs
  • Broken skin

PDSA advises contacting your vet when harvest mites are suspected because treatment may be needed. (PDSA)

Read Harvest Mites on Dogs for the complete guide.

Do not apply an extra flea or parasite product without veterinary advice.

Some products cannot be safely combined.

Seasonal canine illness

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

Its 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.

PDSA advises contacting your vet immediately when these symptoms occur after recent woodland exposure.

Do not assume that vomiting after a walk is simply a mild stomach upset.

Tell your vet:

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

Ticks

Ticks 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:

  • Ears
  • Face
  • Neck
  • Armpits
  • Groin
  • Between the toes

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

Do not:

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

PDSA advises correct removal and veterinary advice when part of the tick may remain, the skin becomes inflamed, or the dog becomes unwell afterwards.

Read Fleas and Ticks on Dogs for fuller guidance.

Fireworks can begin before November

Fireworks do not occur only on the evening of 5 November.

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

A dog who appears comfortable during 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 normal background sound when your dog is accustomed to it
  • Allow your dog to seek reassurance or hide
  • Speak to your vet well before the season when fear is severe

Blue Cross recommends earlier on-lead walks, keeping dogs indoors during fireworks and allowing them access to a safe hiding place. It also advises seeking veterinary or behaviour support well in advance for dogs with significant fear.

Read Dogs and Fireworks: Complete UK Safety Guide.

Do not force an evening walk during fireworks.

Your dog still needs an opportunity to toilet, but a normal long evening walk may not be appropriate when fireworks are already sounding.

Depending on the dog, a safer arrangement may involve:

  • An earlier walk
  • A brief lead toilet break
  • Secure garden access
  • Indoor scent activities
  • Food enrichment
  • Calm companionship
  • A shorter route close to home

Do not drag a frightened dog outside.

Do not allow an anxious dog off lead because the park appears quiet.

Storms and sudden weather changes

Autumn can bring:

  • Heavy rain
  • Thunder
  • Lightning
  • Strong winds
  • Flooding
  • Falling branches
  • Damaged fencing

Check the 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 letting the dog outside.

PDSA recommends checking fences and gardens after strong winds and ensuring animals have a dry, secure environment during heavy rain.

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

Thunder and noise-sensitive dogs

A dog frightened by thunder may:

  • Tremble
  • Pant
  • Pace
  • Hide
  • Bark
  • Refuse food
  • Follow you closely
  • Try to escape

Plan the walk before the worst weather arrives where practical.

At home:

  • Close windows
  • Give access to a familiar safe area
  • Remain calm
  • Allow your dog to choose proximity or distance
  • Avoid punishment
  • Contact your vet when the fear is severe or worsening

Read Walking Dogs in Rain, Wind and Thunder for more detailed guidance.

Sticks

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 because the wood itself, mould, chemicals or plant species may create additional risks.

Read sticks and danger

Wildlife

Autumn walks may bring dogs closer to:

  • Squirrels
  • Foxes
  • Deer
  • Birds
  • Badgers
  • Other wildlife

Keep your dog under control and prevent chasing.

You do not need to treat normal wildlife as an automatic threat.

The sensible approach is to:

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

The old article described badgers and snakes in an unnecessarily dramatic way.

That material should be removed.

Plants, cuttings and autumn gardening

Autumn garden work may leave dogs with access to:

  • Bulbs
  • Berries
  • Prunings
  • Compost
  • Fertiliser
  • Weed killers
  • Slug products
  • Mushrooms
  • Mouldy leaves

Clear cuttings promptly and keep garden products in their original labelled containers.

Do not assume that a natural or organic product is safe for dogs.

Read Plants Poisonous to Dogs for the main garden-safety guide.

Antifreeze

Antifreeze containing ethylene glycol can cause severe poisoning and kidney damage.

Store it securely and clean up spills immediately.

Do not allow your dog to drink from puddles near:

  • Garages
  • Driveways
  • Parked vehicles
  • Workshops
  • Car parks

Contact your vet immediately when antifreeze exposure is possible.

Do not wait for symptoms or attempt a home remedy.

The old article correctly identified antifreeze as serious, but this subject belongs mainly in the wider poison and winter-safety guides rather than dominating the autumn walking page.

Senior dogs in autumn

Cooler and 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 the dog previously managed it.

A senior dog may benefit from:

  • A shorter route
  • A slower pace
  • More sniffing time
  • Several brief walks
  • A flatter surface
  • Additional indoor enrichment
  • Veterinary assessment of new or worsening discomfort

Do not give garlic, herbal tablets or joint supplements merely because an old article recommends them.

Discuss pain, arthritis and supplements with your veterinary practice.

Puppies

Autumn gives puppies many new experiences:

  • Leaves
  • Mud
  • Umbrellas
  • Dark streets
  • Fireworks
  • People in costumes
  • Wet surfaces
  • Wildlife
  • New smells

Introduce experiences gradually.

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

Use calm, reward-based exposure and give the puppy time to rest.

Keep close watch for swallowing leaves, acorns, conkers, stones or litter.

Nervous and rescue dogs

Autumn can be difficult for dogs who rely on predictability.

Their normal route may suddenly involve:

  • Darkness
  • Fireworks
  • Wind
  • People wearing hoods
  • Umbrellas
  • Children in costumes
  • Slippery paths
  • More crowded daylight walking times

Adapt rather than forcing the dog through it.

You may need to:

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

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

Post-walk checks

After an autumn walk, check:

  • Paw pads
  • 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

Read How to Check Your Dog After a Walk.

What to carry on an autumn walk

A practical autumn walking kit may include:

  • Fixed-length lead
  • Secure harness or collar
  • Waste bags
  • Torch
  • Charged phone
  • Water
  • Portable bowl
  • Clean towel
  • Sterile gauze
  • Simple first-aid supplies
  • Veterinary contact details
  • Familiar rewards

A first-aid kit supports your dog while you obtain professional help.

It does not turn a deep wound, poisoning or serious illness into a home-treatment situation.

Read my Dog First Aid Guide.

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 the 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 on a shorter lead
  • Reduce the distance
  • Provide a toilet break and indoor enrichment
  • Return home early when conditions become unsafe

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

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

Frequently asked questions

Are conkers poisonous to dogs?

Yes.

Conkers contain aesculin and may also cause choking or a digestive blockage. Contact your vet immediately when your dog eats one. (Blue Cross)

Are acorns poisonous to dogs?

Yes.

Acorns contain tannins and may cause digestive illness or blockage. Contact your vet after suspected ingestion. (Blue Cross)

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 when my dog eats a mushroom?

Move your dog away, 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 can cause intensely itchy, inflamed skin.

Do ticks disappear in autumn?

Not necessarily.

Ticks can remain active during mild weather, especially in long grass and woodland.

Check your dog after walking and remove ticks correctly. (PDSA)

Should dogs drink from puddles?

It is safer to offer clean water.

Puddles may contain bacteria, chemicals, oil, road residue or antifreeze.

Are wet leaves dangerous?

Leaves can be slippery and may conceal glass, food, holes and other hazards.

Slow down and keep your dog closer when the ground cannot be seen.

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.

See my fireworks guide.

Should I comfort a frightened dog?

Yes, when your dog seeks reassurance.

Remain calm, allow them to hide when they choose and do not punish fearful behaviour. PDSA advises following the dog’s preference for company or space.

Should dogs wear reflective equipment?

Reflective or illuminated equipment can improve visibility, but it must fit safely and should not replace attentive handling, a secure lead or road awareness.

Can I throw sticks for my dog?

No.

Sticks can cause serious mouth, throat and internal injuries. Use a suitable dog toy instead.

How should I dry my dog after a wet walk?

Use a clean towel and pay attention to:

  • Paws
  • Between the toes
  • Belly
  • Chest
  • Lower legs

Do not rub inflamed skin aggressively.

When should I contact a vet after an autumn walk?

Contact your vet when 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 difficulty
  • Collapses

Autumn walks should remain enjoyable

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

It is a lovely season for quiet sniffing walks, cooler temperatures and exploring familiar North London routes.

The important changes are practical:

  • Walk before it becomes too dark
  • Watch what is hidden beneath leaves
  • Prevent your dogfrom eating conkers, acorns and fungi
  • Check for mites and ticks
  • Prepare before fireworks begin
  • Change the route during storms or high winds
  • Check your dog after the walk
  • Contact your vet promptly when something has been eaten, or your dog becomes unwell.l

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

For advice covering all four seasons, visit Seasonal Pet Safety in Finchley.
