First Aid on Dog Walks: What to Watch For and What to Do

Updated September 2026

Most dog walks are completely uneventful.

But cuts, sudden limping, overheating, insect stings, grass seeds, and dogs eating things they shouldn’t can happen surprisingly quickly.

You do not need to turn every walk into a medical inspection. What helps is knowing what is normal for your dog, noticing when something suddenly changes and knowing which situations need veterinary help.

I have worked professionally with dogs since 2011 and hold an Ofqual Level 3 qualification in Canine First Aid. On my one-to-one walks, I can concentrate on the individual dog rather than managing a group, which makes changes in movement, breathing or behaviour easier to notice.

If your dog collapses, struggles to breathe, is bleeding heavily, has a serious eye injury, appears severely unwell or you suspect poisoning or heatstroke, contact a veterinary professional urgently.

What should I watch for while walking my dog?

You know your own dog better than anyone.

Instead of looking for a long list of illnesses, watch for sudden changes.

That might include:

• limping or refusing to put weight on a leg
• repeatedly stopping or refusing to continue
• unusually heavy or persistent panting
• weakness or wobbliness
• vomiting or diarrhoea
• sudden scratching or pawing at the face
• excessive drooling
• holding an eye closed
• repeated head shaking
• bleeding
• swelling
• suddenly becoming very quiet
• confusion or disorientation
• difficulty breathing
• collapse

Not every change means an emergency.

But a sudden change deserves your attention.

My Dog Health & First Aid Guide explains the wider signs worth knowing.

Stop before trying to diagnose the problem

If something looks wrong during a walk, my first response is usually very simple.

Stop.

Move somewhere safe.

Give the dog a moment.

Then look at the whole dog instead of fixating on the first thing you notice.

Ask yourself:

• Are they responsive?
• Are they breathing normally?
• Can they stand?
• Can they walk normally?
• Is there obvious bleeding?
• Do they appear to be in significant pain?
• Has something just happened, such as a fall, collision, bite or sting?
• Could they have eaten something?

A frightened or painful dog may behave differently from normal, including a dog who is usually perfectly comfortable being handled.

Do not force an examination if doing so puts you or the dog at risk.

What should I do if my dog cuts a paw?

Paw cuts are one of the more obvious injuries that can occur outdoors.

Glass, sharp stones, metal, thorns and other rubbish can all cause problems.

If you notice blood or sudden limping, stop the walk and look at the paw if your dog will comfortably allow it.

For a small superficial cut or graze, use clean lukewarm water or saline to flush away dirt.

If the wound is bleeding heavily, use a clean dressing or cloth and apply firm pressure.

Do not repeatedly remove the dressing to check whether the bleeding has stopped because this can disturb the developing clot.

If glass or another object is embedded in the wound, leave it in place and contact your vet. Pulling it out can increase bleeding or cause additional damage.

Deep wounds, heavily bleeding wounds, painful wounds and wounds containing foreign material need veterinary assessment.

Read my full Cuts and Grazes in Dogs guide for more detail.

What should I do if my dog suddenly starts limping?

Stop rather than trying to make your dog finish the walk.

A limp can be caused by something relatively simple, such as a stone between the toes, but it can also involve a damaged nail, cut, grass seed, sprain, joint problem or more significant injury.

If your dog will let you, look for:

• cuts
• damaged nails
• swelling
• thorns
• stones or debris between the toes
• grass seeds
• something stuck in a paw

Do not dig into the skin or pull out something that appears embedded.

If your dog cannot bear weight, seems very painful, has obvious swelling or the limp follows significant trauma, contact your vet.

A milder limp that does not settle also deserves veterinary advice.

What should I do if my dog overheats on a walk?

Heatstroke is a veterinary emergency.

Possible warning signs include:

• excessive or persistent panting
• distressed or noisy breathing
• drooling
• red gums or tongue
• restlessness
• repeatedly seeking shade or water
• vomiting or diarrhoea
• weakness
• confusion
• wobbliness
• collapse
• seizures

If you suspect heatstroke, do not simply put the dog in the car and drive to the vet without beginning cooling.

Current Royal Veterinary College guidance is:

Cool first, transport second.

Move the dog somewhere cooler and well ventilated.

Use water cooler than the dog and, where possible, combine wetting with air movement from a fan, breeze, or air conditioning. Healthy, conscious younger dogs can also be cooled by water immersion where appropriate. Contact your vet as soon as cooling has started and follow their instructions.

Do not rely on the old advice that dogs must only be cooled slowly with tepid water. RVC research specifically identifies slow cooling as outdated advice.

This is one area where first-aid recommendations have changed, which is why old dog-care articles need reviewing rather than being left online indefinitely.

Read my dogs and heatstroke guide

What if my dog is stung by a bee or wasp?

Most insect stings cause local discomfort rather than a serious emergency.

You might notice:

• licking or biting an area
• mild swelling
• limping
• pawing at the face
• whining
• drooling

If you can clearly see a bee sting, PDSA advises gently scraping it away rather than squeezing the venom sac. A cold, damp cloth may help soothe a mild local reaction.

More serious signs include:

• rapid swelling, particularly around the face or throat
• difficulty breathing
• vomiting or diarrhoea
• widespread hives
• collapse

These need urgent veterinary attention. Multiple stings also warrant prompt veterinary advice.

Do not give a human antihistamine simply because somebody online suggests a dose.

Speak to your vet first.

What should I do if I find a tick?

Ticks are common enough that I think every regular dog walker should know what they look like and how to remove one correctly.

If you find an attached tick, use a proper tick-removal tool if you are confident doing so.

With a tick-twisting hook:

1. Choose the correct-sized tool.
2. Slide it beneath the tick close to the dog’s skin.
3. Twist it in one direction until the tick releases.
4. Lift it away once released.
5. Check the site afterwards and monitor your dog.

Do not crush or squeeze the tick and do not simply pull sharply upwards.

If the tick is close to an eye or another difficult area, your dog will not remain still, or you are not comfortable removing it, ask your veterinary practice for help.

My Fleas and Ticks on Dogs guide covers checking and removal in more detail.

Grass seeds can cause sudden problems

Grass seeds can become trapped in coats but can also work their way into:

• paws
• ears
• eyes
• noses
• skin

After walking through long or dry grass, sudden symptoms can include:

• limping
• licking one paw
• repeated head shaking
• sudden sneezing
• squinting
• holding an eye closed
• pawing at the face

A loose grass seed sitting on the coat can be removed.

A seed that has entered the skin, ear, nose or eye is different.

Do not start digging around trying to find it.

Contact your vet.

Read my Grass Seed Guide

What if my dog eats something while we are out?

Dogs can pick things up before we have even realised they have stopped.

Common outdoor risks can include discarded food, medication, fungi, chemicals, garden products and food containing ingredients toxic to dogs.

If you think your dog has swallowed something potentially harmful:

• move them away from the remaining substance
• identify what they may have eaten if possible
• keep packaging or take a photograph where relevant
• estimate how much they might have eaten
• note approximately when it happened
• phone your vet

Do not wait for symptoms to appear.

Some toxins do not cause obvious signs immediately.

And do not try to make your dog vomit unless a veterinary professional specifically instructs you to do so. In some situations vomiting can cause additional harm. (PDSA)

My Toxic Foods for Dogs guide covers common food hazards, while the First Aid hub covers poisoning more broadly.

What if another dog bites my dog?

Once the dogs are safely separated, check your dog carefully.

Do not assume a tiny puncture means a tiny injury.

Bite wounds can hide damage underneath the skin and are particularly prone to infection. PDSA recommends veterinary assessment after a dog has been bitten or attacked. (PDSA)

Contact your vet even if the visible wound looks relatively small.

Heavy bleeding, breathing difficulties, collapse, severe pain, eye injuries and wounds involving the chest, neck or abdomen require particularly urgent attention.

What if my dog injures an eye?

Eye problems deserve prompt veterinary advice.

Look for:

• squinting
• repeatedly blinking
• holding an eye shut
• redness
• swelling
• excessive tearing
• discharge
• cloudiness
• pawing at the face
• blood
• a visible object
• changes in the pupil

Do not start probing around the eye or trying to remove an embedded object yourself.

PDSA advises contacting a vet as soon as you notice an eye problem because some conditions can worsen quickly and threaten vision.

Read my recently updated Dog Eye Injuries: First Aid, Warning Signs and When to Call a Vet guide.

Know the signs that mean the walk is over

There are occasions when changing the route or taking a short rest is enough.

There are others when the walk is finished.

I would stop and seek veterinary advice promptly if a dog showed:

• difficulty breathing
• collapse or severe weakness
• uncontrolled bleeding
• severe or sudden pain
• significant trauma
• repeated vomiting
• seizures
• a serious eye problem
• suspected poisoning
• suspected heatstroke
• severe allergic reaction
• inability to use a leg normally

You do not need to diagnose the cause before phoning your vet.

Describe what happened and what you can see.

Let the veterinary team decide what should happen next.

Check your dog when you get home

One of the easiest ways to find small problems early is a quick post-walk check.

I pay particular attention to:

Paws

Check pads, nails and between the toes for cuts, thorns, grass seeds and debris.

Legs

Notice swelling, tenderness or a change in movement.

Ears

Look for anything unusual and pay attention to repeated head shaking.

Eyes

Check for redness, excessive watering, squinting or anything caught around the eye.

Coat and skin

Run your hands over the coat looking and feeling for ticks, seeds, sore patches or small injuries.

Harness and collar areas

Check for rubbing and anything trapped beneath equipment.

This does not need to become a lengthy examination after every walk.

It is simply learning what is normal for your dog.

What I carry on my dog walks

I do not try to carry a miniature veterinary surgery.

A practical first-aid kit is there to help with the first few minutes of an incident and while professional help is being arranged.

Useful items include:

• sterile dressings
• gauze
• appropriate bandage material
• disposable gloves
• sterile saline
• tick-removal tool
• blunt-ended scissors
• foil blanket
• clean towel
• spare lead
• phone
• client and veterinary emergency information

Knowing how to use these things matters more than simply owning them.

My Dog First Aid Kit for Home and Walks guide explains what I keep and why.

Why one-to-one walking helps me notice changes

One reason I chose to offer solo walks rather than collecting groups of dogs in a van is that I can pay attention to the individual dog in front of me.

I get to know:

• their normal walking pace
• how they usually move
• how heavily they normally pant
• whether they usually stop frequently
• how they behave around people and dogs
• where they normally like being touched
• what is unusual for them

That does not make me a vet.

But knowing the dog’s normal behaviour can make an unexpected change much easier to spot.

If you are looking for calm local walking where your dog receives individual attention, you can read about my Solo Dog Walks in Finchley and surrounding areas.

Learning first aid before an emergency

The middle of an emergency is not the ideal time to discover what is in your first-aid kit.

A canine first-aid course can help you practise assessing a dog, responding to common emergencies and understanding when veterinary intervention is needed.

I have completed canine first-aid training myself and believe it is worthwhile for dog owners as well as pet professionals.

One course I recommend is Rachel Bean RVN’s Canine First Aid Course. This is an affiliate link, so I may receive a commission if you enrol through it at no additional cost to you.

A course does not turn you into a veterinary professional.

It does help you understand what you can safely do while veterinary care is being arranged.

Frequently asked questions

Should I carry a first-aid kit on every dog walk?

For ordinary local walks, a small practical kit is useful. On longer or more remote walks, carrying appropriate emergency supplies becomes even more important. The aim is not to carry everything. It is to have a few useful items you know how to use.

Should I remove glass from my dog’s paw?

If glass is embedded in a wound, do not pull it out. Leave it in place and contact your vet because removal can increase bleeding or cause further damage.

Can I give my dog an antihistamine after a sting?

Speak to your vet first. Some antihistamines may be used in dogs, but the appropriate medicine and dose depend on the individual dog and situation.

Should I use tweezers to remove a tick?

A purpose-made tick-removal tool is preferable. PDSA advises against pulling, crushing or squeezing a tick. A tick-twisting hook is slid underneath the tick and rotated until it releases.

Should I wait to see whether suspected poisoning causes symptoms?

No. Contact your vet promptly if you think your dog has swallowed something poisonous. Symptoms can sometimes take hours or longer to appear.

Should I finish the walk if my dog suddenly starts limping?

No. Stop and assess your dog rather than making them complete the route. Check the paw if it is safe to do so and seek veterinary advice if they are very painful, cannot bear weight or the problem does not settle.

Preparation matters more than panic

Most walks will not involve an emergency.

That is precisely why preparation works best before you need it.

Know your dog.

Carry a sensible first-aid kit.

Have your veterinary contact details available.

Check your dog after walks.

Learn basic canine first aid.

And when something does happen, remember that you do not have to diagnose it yourself.

Sometimes the best first-aid decision you can make is stopping the walk and phoning your vet.
