Updated July 2026
Broken glass is one of the walking hazards I regularly watch for on pavements, paths and grass verges around Finchley.
It can be difficult to see, particularly in long grass, fallen leaves or poor light. A dog may step on a shard before you realise it is there.
Some glass injuries are small surface cuts. Others penetrate deeply into a paw pad, become embedded between the toes or damage a tendon, nail or blood vessel.
The wound visible on the surface may not show the full extent of the injury.
If your dog has stepped on glass, move them away from the area, keep them calm and check the paw without forcing them to tolerate painful handling.
Do not pull out deeply embedded glass.
Do not probe the wound with tweezers.
Do not give human painkillers.
If your dog may have swallowed glass, contact your vet immediately. Do not make them vomit or feed cotton wool, bread or another home remedy.
For broader first-aid advice, read my Dog First Aid Guide for Owners.
The quick answer
If your dog steps on broken glass:
- Move them away from the remaining glass.
- Keep them as still and calm as possible.
- Check for heavy bleeding and other injuries.
- Apply clean, firm pressure to a bleeding wound when no object is protruding.
- Do not remove embedded glass.
- Do not press directly onto a protruding object.
- Contact your veterinary practice.
- Prevent further walking and licking.
- Transport your dog carefully.
PDSA advises that wounds containing an object such as glass need urgent veterinary attention. The object should not be removed at home because it may be deep, may cause more damage during removal or may be limiting bleeding. (PDSA)
Why broken glass can cause a serious paw injury
A dog’s paw pads are tough, but they are not resistant to sharp objects.
Broken glass can cause:
- surface cuts
- deep lacerations
- puncture wounds
- damage between the toes
- torn pad tissue
- injury around a nail
- damage to tendons or other deeper structures
- pieces remaining beneath the skin
- bleeding
- infection
- pain when standing or walking
A small opening can hide a deeper track beneath the surface.
Glass can also break into several fragments. Removing one visible piece does not prove the paw is clear.
Where dogs may encounter broken glass
Glass can be found on:
- pavements
- residential streets
- park paths
- grass verges
- woodland routes
- car parks
- near public bins
- around benches
- outside pubs and takeaways
- beaches
- riverbanks
- picnic areas
- festival or event sites
- areas where fly-tipping has occurred
Dark glass can blend into soil, mud and wet leaves.
Clear glass may be almost invisible until sunlight reflects from it.
After dark, use a torch or phone light where necessary and keep your dog closer in areas with poor visibility.
Signs that your dog may have cut their paw
A dog with a glass injury may:
- yelp suddenly
- stop walking
- hold one paw up
- limp
- refuse to put weight on the leg
- lick or chew the paw
- leave bloody marks
- appear anxious or unsettled
- repeatedly look at the foot
- resist having the paw touched
- walk normally at first and become lame later
Not every glass injury bleeds heavily.
A small puncture may close at the surface while glass remains deeper inside.
Contact your vet when lameness continues, the dog appears painful, or you suspect a foreign object.
First, move away from the broken glass
Do not examine the paw while standing in the middle of the affected area.
Move your dog carefully onto:
- a clear pavement
- clean grass
- a towel
- another visibly safe surface
Keep other dogs and people away from the glass.
If your dog is small and will accept safe handling, you may be able to carry them.
Do not lift a large or frightened dog in a way that risks dropping them or causing further injury.
A painful dog may behave differently from normal. Move slowly and avoid placing your face near their mouth.
Keep your dog calm
Movement can:
- increase bleeding
- drive glass further into the tissue
- enlarge the wound
- cause another fragment to enter the paw
- make examination more difficult
Encourage your dog to remain still.
Use a calm voice and avoid crowding them.
Do not force them onto their side or repeatedly squeeze the paw.
When your dog is frightened, defensive or in significant pain, stop examining them and contact your vet.
Check for other injuries
Your dog may have:
- stepped on several pieces
- cut more than one paw
- fallen after the injury
- cut their mouth while investigating the glass
- damaged a nail
- swallowed a fragment
Check quickly for:
- heavy bleeding
- glass protruding from the paw
- cuts on another foot
- blood around the mouth
- drooling
- gagging
- breathing difficulty
- collapse
- pale gums
- severe distress
Breathing difficulty, collapse, uncontrollable bleeding or suspected glass ingestion requires urgent veterinary help.
How to examine the paw safely
Only examine the paw when your dog will allow it.
Use good lighting and look at:
- the main paw pad
- smaller toe pads
- spaces between the toes
- around each nail
- the top of the foot
- the lower leg
Look for:
- cuts
- punctures
- blood
- swelling
- glass
- grit
- discolouration
- a damaged nail
- torn skin
Do not spread the toes forcefully.
Stop when your dog:
- pulls away
- freezes
- growls
- turns towards your hand
- cries
- pants heavily
- becomes increasingly distressed
A growl is a warning that the dog is uncomfortable. Do not punish it.
Do not remove embedded glass
The old article advised using tweezers to remove glass.
That instruction should not remain.
Do not remove glass when it is:
- embedded in the paw
- protruding from a wound
- difficult to grip
- deep
- surrounded by heavy bleeding
- close to a joint or tendon
- painful to touch
- likely to break
Pulling it out may:
- enlarge the wound
- break the glass
- leave fragments behind
- damage deeper structures
- restart or increase bleeding
- make veterinary removal more difficult
PDSA specifically advises leaving objects such as glass inside a wound for veterinary removal.
What if a tiny loose fragment is sitting on the surface?
Do not dig into the wound.
A fragment resting freely on the surrounding hair or skin may fall away during gentle rinsing, but you should not probe beneath the surface or attempt to establish how deeply it extends.
When you are unsure whether the glass is embedded, treat it as embedded and contact your veterinary practice.
A photograph may help the veterinary team understand what you can see, provided taking it does not delay care.
How to control bleeding
When the wound is bleeding and no object is protruding:
- Place a clean, dry dressing or folded gauze over it.
- Apply steady pressure.
- Keep the dog still.
- Contact your vet.
- Continue pressure during transport when advised.
Do not repeatedly lift the dressing to see whether bleeding has stopped.
If blood soaks through, place another clean dressing on top rather than pulling the first one away.
PDSA advises firm pressure with a clean dressing for a heavily bleeding wound and urgent veterinary attention when bleeding does not stop.
When glass is protruding from the wound
Do not press directly onto the glass.
Do not pull it out.
Do not push it further in.
Keep the dog still and contact your vet immediately.
When instructed to cover the injury for transport, place clean material loosely around the object without pressing it into the paw.
Do not attempt an elaborate bandage when you have not been trained to apply one.
A tight or incorrectly positioned bandage can restrict circulation and cause further injury.
Should you rinse the paw?
A small surface wound that is not bleeding heavily may sometimes be gently rinsed with clean, lukewarm water.
This can help remove loose surface dirt.
Do not rinse aggressively when:
- glass is embedded
- bleeding is heavy
- the wound is deep
- the paw is extremely painful
- the dog is resisting
- rinsing would delay urgent treatment
PDSA advises gently flushing a minor wound with clean lukewarm water or a correctly prepared saline solution, while wounds containing glass, heavy bleeding or deep injuries need veterinary care.
Blue Cross recommends using salt water on minor wounds only when your vet has advised that it is appropriate. (Blue Cross)
Do not scrub the wound
Scrubbing can:
- increase pain
- damage tissue
- disturb a clot
- drive debris deeper
- cause more bleeding
Allow water to flow gently over a minor surface injury.
Do not use a brush, cloth or abrasive wipe.
Do not apply household products.
Do not clean the paw with:
- hydrogen peroxide
- surgical spirit
- alcohol
- bleach
- household disinfectant
- essential oils
- tea tree oil
- washing-up liquid
- human antiseptic cream
- wound powder
- an unprescribed spray
Some products damage healing tissue or are harmful if licked.
PDSA advises using only water or the wound treatment recommended by your vet because even some antiseptic products can delay healing.
Do not give human painkillers.
Never give your dog:
- ibuprofen
- paracetamol
- aspirin
- naproxen
- another person’s prescription medicine
- medication left from another pet
Human painkillers can be highly toxic to dogs.
Your vet can prescribe pain relief that is appropriate for your individual dog and injury. Blue Cross advises never giving human medication to a dog.
Protecting the paw for the journey
Your veterinary practice may advise placing a clean, non-stick dressing over the injury for transport.
The aim is to:
- reduce contamination
- limit further bleeding
- stop the dog licking
- protect the wound during movement
Do not:
- wrap tightly
- use an elastic band
- put adhesive tape directly onto fur or skin
- place pressure over embedded glass
- leave a temporary covering on without veterinary advice
- allow the covering to become wet
- allow your dog to chew it
When you cannot cover the wound safely, keep your dog still and transport them without attempting a complicated bandage.
Prevent licking
Licking can:
- reopen the wound
- introduce bacteria
- delay healing
- remove dressings
- worsen inflammation
Supervise your dog.
A veterinary practice may recommend:
- a correctly fitted recovery collar
- a protective boot
- a bandage
- another suitable barrier
Do not place a tight sock, plastic bag or improvised cover on the paw for a prolonged period.
Plastic can trap heat and moisture, while a tight covering may restrict circulation.
Transporting your dog
Avoid allowing your dog to walk unnecessarily.
For a small dog, support the chest and hindquarters while carrying them.
For a larger dog, your vet may advise using:
- a towel as support
- a blanket
- a board or other firm surface
- help from another adult
Keep the dog secure in the vehicle.
Do not allow an injured dog to jump into or out of the car.
Phone the veterinary practice before leaving so it knows:
- the dog has a possible glass injury
- whether glass remains embedded
- how much bleeding is present
- whether the dog can bear weight
- whether ingestion is possible
- how far away you are
When does a paw cut need a vet?
Contact your vet promptly when:
- glass may be embedded
- the wound is deep
- the edges gape apart
- bleeding is heavy
- bleeding has not stopped after sustained pressure
- the paw pad is split
- tissue is missing
- the cut lies between the toes
- a nail is damaged
- your dog cannot bear weight
- pain is significant
- more than one paw is affected
- the wound is dirty
- the injury occurred at the beach or in contaminated water
- your dog will not allow examination
- the wound reopens when walking
- you are uncertain how serious it is
PDSA classifies wounds containing glass, deep wounds and heavy bleeding as injuries requiring urgent veterinary assessment. (PDSA)
Why paw-pad cuts can be difficult to heal
Dogs place weight on their paw pads with every step.
A paw-pad cut may repeatedly:
- open
- stretch
- bleed
- collect dirt
- become wet
- be licked
The area can be difficult to rest fully.
Your vet may need to assess whether the injury requires:
- deeper cleaning
- pain relief
- stitches or staples
- a professional bandage
- imaging
- treatment for infection
- restricted exercise
- sedation or anaesthesia
Do not assume that a small visible cut is trivial when your dog remains lame.
Why imaging may be needed
Glass may remain beneath the skin even when it cannot be seen.
Your vet may recommend imaging or further examination when:
- the wound is deep
- lameness continues
- a fragment is suspected
- swelling develops
- the cut repeatedly opens
- pain remains after initial treatment
- the original glass broke into several pieces
Do not attempt to locate hidden glass by squeezing or probing the paw.
Cuts between the toes
Cuts between the toes can be difficult to see.
Watch for:
- repeated licking
- swelling
- redness
- limping
- discharge
- an unpleasant smell
- pain when the toes separate
- blood after walking
The skin between the toes moves and becomes moist, which can make healing more difficult.
Arrange veterinary advice rather than repeatedly applying home remedies.
Glass injuries around the nails
Broken glass may:
- cut the skin beside a nail
- split the nail
- damage the nail bed
- become lodged beneath a nail
- cause bleeding from the toe
Nail injuries can be extremely painful.
Do not pull off a damaged nail or cut deeply into it.
Contact your vet when:
- the nail is hanging
- bleeding continues
- the toe is swollen
- the dog will not bear weight
- glass may be lodged beneath it
Signs of infection
Check the paw as it heals.
Possible infection signs include:
- increasing redness
- swelling
- warmth
- discharge
- pus
- an unpleasant smell
- increasing pain
- renewed bleeding
- continued licking
- worsening lameness
- low energy
- reduced appetite
Contact your vet when the wound deteriorates or is not healing as expected.
PDSA advises monitoring every wound for redness, swelling, discharge and other signs of infection.
Follow the veterinary recovery plan
Your vet may advise:
- restricted walking
- keeping a dressing dry
- regular bandage changes
- prescribed pain relief
- antibiotics when infection is present
- use of a recovery collar
- follow-up appointments
- gradual return to exercise
Do not remove a veterinary bandage early unless instructed.
Contact the practice when:
- the bandage becomes wet
- it slips
- it smells
- the toes swell
- the dog chews it
- the dog appears increasingly uncomfortable
What if my dog swallowed broken glass?
Treat suspected glass ingestion as an emergency.
Contact your veterinary practice immediately, even when your dog currently appears normal.
Sharp glass can injure:
- the lips
- mouth
- tongue
- throat
- oesophagus
- stomach
- intestines
Sharp or spiky foreign bodies may tear the digestive tract and cause a severe internal infection. PDSA advises contacting a vet immediately whenever a dog has swallowed something they should not have, particularly a sharp object. (PDSA)
Do not wait for symptoms.
Early veterinary assessment may give the team more options than waiting until the glass has moved further through the digestive system.
Do not make your dog vomit.
Do not attempt to make your dog sick.
Glass could cause further damage as it comes back through the:
- stomach
- oesophagus
- throat
- mouth
Do not use:
- salt
- mustard
- hydrogen peroxide
- washing soda
- fingers in the throat
- another home method
Only a veterinary professional should decide whether vomiting is safe and appropriate after any foreign-object ingestion.
With sharp material, it may not be safe.
Do not feed cotton wool.
The old version of this article advised feeding cotton-wool balls dipped in cream so they would supposedly wrap around the glass.
Delete that advice completely.
Do not feed:
- cotton wool
- cotton pads
- bread
- cream
- bulky meals
- mashed potato
- oil
- butter
- bran
- another substance intended to cushion the glass
These are not treatments.
Cotton wool is itself an indigestible foreign object and could create an additional obstruction risk.
Call your vet and follow its instructions about food and water.
Do not give food before speaking to the vet
Your dog may need:
- sedation
- endoscopy
- diagnostic imaging
- anaesthesia
- surgery
Feeding may affect how and when some procedures can be carried out.
Do not offer a large meal or home remedy unless the veterinary team tells you to do so.
Tell the vet when your dog last ate and drank.
Signs of injury after swallowing glass
Possible signs include:
- cuts or blood in the mouth
- excessive drooling
- pawing at the mouth
- gagging
- repeated swallowing
- coughing
- retching
- vomiting
- blood in vomit
- reduced appetite
- abdominal pain
- a tense abdomen
- unusual posture
- low energy
- straining to pass faeces
- blood in faeces
- black or tar-like faeces
- weakness
- collapse
Do not wait for these signs before calling.
A dog may appear normal during the early stages of a serious foreign-body injury. PDSA advises immediate contact after suspected foreign-object ingestion because waiting can reduce the available treatment options.
What if glass is visible in the mouth?
Do not reach deeply into your dog’s mouth.
A painful or frightened dog may bite.
Do not pull an object that appears:
- embedded
- caught beneath the tongue
- lodged in the roof of the mouth
- trapped in the throat
- connected to something swallowed
Keep your dog calm and contact your vet immediately.
Only remove an item when the veterinary team explicitly advises you, and it is loose, easily accessible and safe to remove.
What information should you give the vet?
Tell the veterinary team:
- what happened
- when it happened
- whether you saw the dog swallow glass
- the approximate size and shape
- whether the glass was sharp
- whether pieces are missing
- whether the dog has eaten or drunk since
- any symptoms
- your dog’s size and age
- relevant health conditions
- current medication
Where it is safe, photograph the remaining glass or broken object.
Do not carry loose shards in your hand.
Preventing broken-glass injuries
You cannot prevent every accident, but you can reduce the risk.
During walks:
- look ahead
- keep your dog closer around litter
- avoid areas where bottles are visible
- shorten a long line on narrow paths
- use a torch in poor light
- prevent scavenging
- avoid recently used party or picnic areas
- turn around when the path is unsafe
- check paws after walking through suspicious areas
Changing the route is not an overreaction.
The walk can continue somewhere safer.
Check your dog after the walk.
When you passed through an area containing litter or broken glass, check:
- all four paw pads
- between the toes
- around the nails
- lower legs
- mouth where scavenging occurred
Also watch how your dog moves around the home.
A dog may show lameness only after the excitement of the walk has passed.
Carry a simple dog first-aid kit
A practical walking kit may contain:
- sterile gauze
- clean non-stick dressings
- a conforming bandage
- sterile water or wound wash
- a clean towel
- disposable gloves
- your vet’s contact details
- an emergency veterinary number
Blue Cross recommends carrying clean dressings, gauze, sterile water, a towel and veterinary contact details in a dog first-aid kit.
The kit is for immediate support while you obtain help.
It does not make you responsible for diagnosing or treating a deep paw injury.
Should a dog first-aid kit contain tweezers?
Tweezers may have a role for some surface items, such as a visible loose thorn, when you have been trained, and the item is clearly not embedded.
They should not encourage you to dig into a glass wound.
When glass is visible inside a cut, leave it for the vet.
The safest first-aid decision is often knowing when to stop.
Reporting broken glass in Barnet
Broken glass on a public street or pavement can be reported as a street-cleaning issue through Barnet Council’s road, street and pavement reporting service.
Barnet Council provides a specific route for reporting street-cleaning problems requiring attention.
Provide:
- the exact location
- a nearby house number or landmark
- a photograph where safe
- whether the glass covers the full pavement
- whether it is near a school, playground or park entrance
- whether it creates an immediate danger
For glass inside a park, report it to the park manager or relevant landowner.
Should you pick up the glass yourself?
Do not handle broken glass with bare hands.
Do not risk cutting yourself or allowing your dog to move back into the area.
Where a very small amount can be removed safely, use:
- thick protective gloves
- a suitable rigid container
- appropriate cleaning equipment
Never place loose glass inside a thin bag or ordinary pocket.
When the area is extensive, unsafe or contaminated, keep away and report it.
Your safety matters too.
Broken glass at the beach
Glass on a beach may be:
- partly buried
- smoothed by water
- hidden beneath seaweed
- mixed with shells and stones
- exposed as the tide changes
Even apparently smooth beach glass may have sharp edges.
Check paws after the visit and avoid allowing your dog to dig around litter or broken bottles.
Contact the relevant council or beach manager when you find dangerous glass.
Broken glass in woodland and long grass
Grass and leaf litter can hide glass completely.
Be particularly careful around:
- benches
- picnic areas
- fire sites
- path entrances
- car parks
- bins
- areas used for parties
- discarded bottles
Keep your dog close until you have passed the affected section.
Do not assume woodland ground is automatically safer than a pavement.
Nervous and rescue dogs
A nervous dog may find paw examination and bandaging frightening.
After an injury:
- move slowly
- give the dog space
- avoid surrounding them
- limit handling
- use familiar cues
- tell the veterinary practice about handling concerns
- use a muzzle only when it has been appropriately introduced,d or the vet advises emergency use
Pain may change a dog’s behaviour.
A normally gentle dog may growl or snap when a painful foot is touched.
My Rescue Dog Support in Finchley focuses on calm, predictable handling and reducing unnecessary pressure.
How I reduce broken-glass risks during walks
I cannot remove every hazard from a public route, but I can make decisions before the dog reaches it.
During one-to-one walks, I can:
- keep watching the path
- change direction
- cross the road
- shorten the lead
- avoid littered areas
- select another local route
- check the dog’s paws
- tell the owner about a concern
- report dangerous glass
Because my walks begin at the client’s home and do not involve vans or group collections, I can adapt the route around the individual dog.

Frequently asked questions
Should I remove glass from my dog’s paw?
Do not remove embedded or protruding glass.
Keep your dog still and contact your vet. Removing the object may increase bleeding, damage deeper tissue or leave fragments behind. (PDSA)
Can I use tweezers?
Do not use tweezers to probe a glass wound.
When you are unsure whether a piece is embedded, leave it alone and seek veterinary advice.
How do I stop the bleeding?
When no object is protruding, place a clean dressing over the wound and apply steady pressure.
Contact your vet immediately when bleeding is heavy or does not stop. (PDSA)
Should I wash the paw?
A minor surface wound may be gently rinsed with clean, lukewarm water.
Do not scrub, delay urgent care or rinse deeply around embedded glass.
Does every paw cut need a vet?
A very small surface graze may sometimes be managed at home after veterinary advice.
Deep cuts, heavy bleeding, pain, lameness, gaping wounds and injuries containing glass need veterinary assessment. (PDSA)
Can a paw-pad cut need stitches?
Yes.
Your vet will assess the depth, location, contamination and movement of the wound and decide whether stitches, staples, a bandage or another treatment is needed.
Can glass remain inside the paw?
Yes.
Small fragments may remain beneath the skin and cause persistent pain, swelling, infection or lameness. Your vet may recommend further examination or imaging.
Can I give my dog ibuprofen or paracetamol?
No.
Do not give human painkillers. They may be toxic to dogs. Contact your vet for suitable pain relief. (Blue Cross)
What should I do if my dog swallowed glass?
Call your vet immediately.
Do not wait for symptoms, induce vomiting or offer a home remedy. Sharp foreign objects can tear the digestive tract. (PDSA)
Should I feed cotton wool after my dog eats glass?
No.
Cotton wool is not a treatment and is itself an indigestible foreign object. Do not feed cotton wool, bread or bulky food. Follow your vet’s instructions.
Should I make my dog sick?
No.
Vomiting could cause the glass to damage the digestive tract again on the way back up. Only a veterinary professional should decide how the ingestion should be managed.
What if my dog seems completely normal?
Contact your vet anyway when glass ingestion is possible.
Symptoms may not appear immediately, and early assessment may be important.
What if the cut stops bleeding?
The injury may still contain glass or extend deeper than it appears.
Contact your vet when your dog remains lame, painful or reluctant to use the paw.
How can I prevent this happening again?
Look ahead, keep your dog closer around litter, use a light after dark, avoid unsafe paths and report broken glass to the council or landowner.
First aid should protect your dog until professional help is available
When your dog steps on glass, stay calm.
Move away from the hazard.
Keep them still.
Control bleeding when it is safe to do so.
Do not pull embedded glass from the paw.
Do not probe the wound.
Do not give human medication.
If glass may have been swallowed, contact your vet immediately and do not use cotton wool, bread or another home remedy.
The purpose of first aid is not to complete the treatment yourself.
It is to prevent further harm and get your dog safely to the veterinary care they need.

Veterinary disclaimer
This article provides general first-aid and dog-welfare information.
It does not diagnose the depth of a wound, determine whether glass remains inside a paw, prescribe treatment or replace examination by a veterinary surgeon.
Under the Veterinary Surgeons Act 1966, diagnosis and medical or surgical treatment are matters for an appropriately qualified veterinary surgeon.
Contact your veterinary practice immediately after suspected glass ingestion, uncontrollable bleeding, an embedded object, a deep wound, severe pain, collapse or another concerning change.
