Dog Health & First Aid: Practical Advice for Dog Owners

Updated October 2026

Dog first aid is not only about knowing what to do when something dramatic happens.

For me, useful dog health awareness starts much earlier.

It starts with knowing the dog in front of you.

How do they normally move? How interested are they in food? How much do they usually drink? How do they sleep, toilet, interact and cope with their everyday routine?

When you know what normal looks like for your own dog, changes become much easier to notice.

I have worked professionally with dogs since 2011 and hold an Ofqual Level 3 qualification in Canine First Aid. Because I provide one-to-one walks and care for the same dogs regularly, I am often in a good position to notice when a dog suddenly moves, breathes, behaves, or copes differently from normal.

That does not mean diagnosing the problem.

It means noticing change, responding sensibly and involving a veterinary professional when appropriate.

This guide brings together my practical dog health and first-aid information, from everyday wellness and post-walk checks to heatstroke, poisoning, nicotine, wounds, eye injuries and knowing when something cannot wait.

Important: If your dog is struggling to breathe, has collapsed or become unresponsive, is bleeding heavily, is having repeated or prolonged seizures, appears to be in severe pain, cannot pass urine, is repeatedly retching with a swollen abdomen, or you suspect poisoning, heatstroke or serious trauma, contact a veterinary professional urgently.

Start by knowing what a well dog looks like

Before thinking about emergencies, I think every owner should ask a simpler question:

What does well actually look like for my dog?

A well dog is not simply a dog who has not been diagnosed with an illness.

Wellness includes physical health, but it also includes appropriate exercise, nutrition, comfortable movement, sleep, rest, enrichment, emotional wellbeing, predictable routines and feeling safe.

The exact balance will look different for different dogs.

A young Labrador does not have the same needs as a thirteen-year-old terrier.

A confident dog who enjoys busy places does not need the same type of walk as a nervous rescue dog who is happier exploring somewhere quieter.

One dog may love a long woodland walk.

Another may benefit more from a shorter sniffy walk, then going home to rest.

My Pet Wellness Is More Than Physical Health: What Does a Well Dog Actually Look Like? guide looks at that whole-dog picture in much more detail.

It also explains an important point:

Behaviour changes can sometimes be health changes.

A dog who suddenly stops wanting to jump, becomes reluctant to walk, sleeps somewhere unusual, starts avoiding touch or becomes less tolerant around other dogs is giving us information.

It does not automatically mean they are ill.

But if something is persistently or significantly different from that dog’s normal, it is worth noticing.

That links closely to the PDSA’s wider framework of five welfare needs: health, behaviour, companionship, diet and environment.

The aim is not to inspect your dog anxiously all day.

It is simply to know them well enough to recognise change.

Notice change before trying to name it

One of the most useful things canine first-aid training has taught me is that I do not need to diagnose the problem.

Neither does an owner.

Sometimes the most useful observation is simply:

“This isn’t normal for my dog.”

Perhaps they are suddenly:

• moving differently
• breathing differently
• unusually quiet or restless
• struggling to get comfortable
• drinking or toileting differently
• avoiding being touched
• tiring much earlier than normal
• reluctant to use stairs or jump
• refusing food they would normally eat
• behaving in a way that is genuinely out of character

Those changes can have many explanations.

My job as a dog walker is not to decide whether the cause is arthritis, pain, illness, fear or something else.

It is to describe accurately what I have noticed.

My What I Notice on a Dog Walk: Small Changes Worth Mentioning to Your Vet guide explains this approach in more detail.

If you are trying to decide whether a change can reasonably be monitored or deserves veterinary advice now, use When Should I Call the Vet?

What dog first aid actually means

First aid is the immediate support you give before veterinary treatment is available.

Sometimes that involves practical action.

You might apply steady pressure to serious bleeding.

You might begin cooling a dog with suspected heatstroke.

You might move an injured dog away from traffic or another immediate danger.

But first aid also involves knowing what not to do.

Do not start experimenting with medicines.

Do not pull objects from deep wounds.

Do not make a poisoned dog vomit unless a veterinary professional specifically instructs you.

Do not keep walking a dog who suddenly looks painful simply because you booked an hour.

Good first aid is not about proving how much treatment you can perform yourself.

It is about keeping the dog as safe as possible while appropriate professional help is arranged.

Remember too that pain and fear can change behaviour.

Even a normally gentle dog may snap or bite when frightened, injured or struggling to breathe.

When your dog needs urgent veterinary help

Don’t watch for a few hours to see what happens.

Contact a vet urgently if your dog has serious breathing difficulty, collapses, becomes unresponsive, is bleeding heavily, has a prolonged or repeated seizure, appears to be in severe pain, cannot pass urine, repeatedly retches without producing anything while their abdomen is swollen, suffers serious trauma, or you suspect poisoning or heatstroke.

A serious eye injury, bite wound, deep wound or embedded object also deserves prompt veterinary attention.

You don’t need to decide the diagnosis before phoning.

Your vet is much better placed to decide that something can safely wait than you or I are to decide that something serious is probably fine.

For the detailed warning signs, read When Should I Call the Vet?

Heatstroke: cool first, transport second

Heatstroke is a veterinary emergency.

It can happen during exercise as well as when a dog is trapped somewhere hot.

Dogs can also struggle in warm, humid conditions that do not necessarily feel extreme to us.

Warning signs may include unusually heavy panting, distressed breathing, excessive drooling, weakness, vomiting, diarrhoea, confusion, poor coordination, collapse and seizures.

Current veterinary advice is important because some older cooling advice is now outdated.

If you suspect heatstroke, stop exercise, move your dog somewhere cooler and begin cooling straight away.

Current PDSA guidance says cold tap water is suitable and recommends wetting the dog’s body while using air movement from a fan, breeze or air conditioning where possible. Do not wrap an overheating dog in a wet towel because covering them can trap heat. Contact your vet as soon as cooling has started. PDSA

My full Heatstroke in Dogs: Signs, First Aid and When to Call a Vet guide explains the current approach in much more detail. The updated page also explains why the old advice to avoid cold tap water changed.

The simple phrase to remember is:

Cool first. Transport second.

That does not mean delaying veterinary care.

It means starting effective cooling immediately while veterinary help is arranged.

Choking and breathing emergencies

A genuinely choking dog may panic, paw at their mouth, struggle to breathe or become unable to make normal sounds.

Any serious breathing difficulty is an emergency, whether choking is the cause or not.

Do not blindly push your fingers into the mouth or throat of a conscious, frightened dog.

If you can clearly see something easily accessible and it is safe to remove it, follow appropriate first-aid guidance.

If your dog cannot breathe normally, you cannot safely deal with the obstruction or you are unsure what is happening, contact an emergency vet immediately.

For choking techniques I prefer owners to use current veterinary instructions rather than relying on a technique remembered from an old social-media video.

Poisoning: do not wait for symptoms

Dogs investigate with their mouths.

Unfortunately that can involve chocolate, grapes, raisins, human medication, cleaning products, garden chemicals, toxic plants, mouldy food, discarded substances and things found while scavenging.

If you know or suspect that your dog has eaten or been exposed to something poisonous, contact your vet promptly.

Do not wait for symptoms.

Some toxins can take hours or longer to produce obvious signs. PDSA advises contacting a vet as soon as poisoning is suspected and specifically says not to make a pet vomit unless a vet tells you to do so.

Keep packaging, ingredient information, or a photograph of the substance where you can do so safely.

My Dog Poisoning: What to Do If Your Dog Eats Something Toxic guide covers the emergency response.

For food hazards specifically, use Foods Toxic to Dogs: What Owners Need to Avoid.

Cigarette butts, vapes and nicotine products

This deserves its own section because discarded cigarette butts and nicotine products are realistic hazards on everyday walks.

I regularly pass litter around pavements, benches, stations, outdoor seating areas and bins.

A quick scavenging dog can find something before an owner has even realised it is there.

Nicotine exposure can involve:

• cigarettes or cigarette butts
• loose tobacco
• vapes and e-cigarettes
• e-liquid or refill bottles
• nicotine gum
• nicotine patches
• nicotine pouches and lozenges

If your dog eats or chews one of these products, contact your vet or Animal PoisonLine promptly even if your dog currently appears normal.

Do not try to calculate a supposedly safe amount yourself.

The amount of nicotine varies considerably between products, and the dog’s size, amount swallowed, route of exposure and time since it happened all affect the risk.

Animal PoisonLine says nicotine can cause signs rapidly, including drooling, vomiting, diarrhoea, changes in heart rate, agitation, hyperactivity and tremors.

Your dedicated My Dog Ate a Cigarette or Cigarette Butt: What Should I Do? guide also covers vapes, e-liquid, pouches, gum and patches and explains what information your vet is likely to need.

If your dog is already collapsing, convulsing or having breathing difficulties, go directly to urgent veterinary care rather than delaying treatment while researching the substance. Animal PoisonLine gives the same advice for pets already showing serious symptoms.

Cuts, grazes, wounds and bleeding

Paws encounter glass, thorns, sharp stones and discarded rubbish surprisingly easily.

A genuinely small superficial graze differs greatly from a deep, gaping, or heavily bleeding wound.

For minor cuts, current veterinary advice supports simple appropriate cleaning rather than automatically reaching for antiseptics and creams.

If bleeding is significant, apply steady pressure using a clean dressing or cloth and contact your vet.

Do not repeatedly lift the dressing to check whether the bleeding has stopped, as this can disturb the developing clot.

Do not pull an embedded piece of glass, metal, stick or wire out of a wound.

An embedded object may be limiting blood loss, and removing it can cause additional damage.

Read Cuts and Grazes in Dogs: First Aid and When to Call a Vet for detailed wound guidance.

For a penetrating or entanglement injury, my Dog Caught in Barbed Wire: What to Do and When to Call a Vet guide covers that situation separately.

Eye injuries need particular care

Eyes are one area where I would be cautious about home treatment.

Squinting, repeated blinking, redness, swelling, cloudiness, discharge, rubbing at the eye or an obvious injury all deserve attention.

Grass seeds and other foreign material can also become trapped in or around the eye.

Do not start poking around trying to remove something yourself.

PDSA advises owners not to attempt to remove a foreign body from an eye because this can damage the surface and cause an ulcer.

Your full Dog Eye Injuries: First Aid, Warning Signs and When to Call a Vet guide is now updated and should replace the current hub wording that says it is still under review. The live eye page was updated in September 2026 and now follows the more cautious veterinary advice.

Grass seeds and post-walk checks

Not every useful health habit involves an emergency.

One of the simplest things I do after walks is look at the dog.

After long grass, woodland or rougher routes, I pay particular attention to paws, between the toes, nails, ears, eyes, coat and the areas where the harness or collar has been sitting.

Grass seeds deserve particular attention.

They can become trapped in fur and work into the paws, ears, eyes, nose or skin.

Sudden head shaking, sneezing, squinting, licking one paw or an unexplained limp after a walk through long grass is worth noticing.

If a seed is sitting loose on the coat you may be able to remove it before it causes trouble.

If it appears to have entered the skin, ear, eye or nose, contact your vet rather than digging around for it.

Read Grass Seeds and Dogs: Risks, Prevention and Practical Advice.

My broader Check Your Dog After a Walk guide takes you through the whole routine.

Fleas, ticks and other parasites

Parasites are usually a prevention and routine health topic rather than an emergency, but they belong in this wider health cluster.

Dogs in the UK can encounter fleas, ticks, worms, mites and other parasites.

The best prevention plan is not necessarily the same for every dog.

Risk can depend on where they walk, scavenging, wildlife exposure, travel, age, health and other animals in the household.

Your veterinary practice can help you decide what protection is appropriate.

For fleas and ticks specifically, use Fleas and Ticks on Dogs: Signs, Checks and Safe Treatment.

For the wider subject, use Dog Parasites: Fleas, Ticks, Worms and Mites.

The current parasite guide already takes a risk-based approach rather than suggesting every dog should automatically receive the same product on the same timetable.

Limping, pain and changes in movement

Not every health problem begins with something dramatic.

Sometimes the first clue is simply that the dog does something differently.

They might slow down.

Hesitate at a familiar kerb.

Shorten their stride.

Become reluctant to jump.

Take longer to stand after resting.

Stop wanting to complete a route they normally enjoy.

I do not diagnose pain.

What I can notice is a change from that dog’s normal.

If a dog suddenly starts limping during one of my walks, I stop.

I do not encourage them to walk it off so I can complete the booked time.

I can calmly check for something obvious, such as a sore paw or damaged nail, but I do not repeatedly manipulate a painful limb trying to identify the problem myself.

My What I Notice on a Dog Walk: Small Changes Worth Mentioning to Your Vet guide focuses on observation rather than diagnosis.

For older dogs, age-specific pain, mobility, and later-life support should remain primarily under the Senior Dog Care cluster rather than being duplicated here.

Adders, insect stings and less common risks

A suspected adder bite needs veterinary attention.

Keep the dog as calm and still as possible, contact your vet and carry them where this is safe and practical rather than making them walk unnecessarily.

Do not cut, suck or tightly bandage the bite.

Use Adder Bites in Dogs: What to Do if Your Dog Is Bitten by a Snake in the UK for the detailed guidance.

With insect stings, a small local reaction differs from rapidly developing facial swelling, breathing difficulties, weakness, or collapse.

Breathing difficulty or collapse is an emergency.

Do not give human medication simply because somebody online has suggested a dose. Contact your vet.

I would retain a short mention of Alabama rot here too rather than creating another page purely to make the cluster larger.

Alabama rot is rare, but unexplained sores combined with illness, loss of appetite, vomiting or changes in drinking or urination deserve veterinary advice.

A dog first-aid kit should contain things you understand

A first-aid kit is useful.

A huge bag of equipment you have no idea how to use is not.

I keep a larger kit available at home and a smaller practical kit for walks.

Useful basics include clean dressings, gauze, suitable bandaging materials, gloves, blunt-ended scissors, sterile saline, clean towels, a tick-removal tool, a torch, a spare lead and emergency contact information.

The full list, including the products I use or recommend, belongs on Dog First Aid Kit for Home and Walks: What to Include.

That page owns the product and first-aid-equipment intent.

This Health & First Aid hub does not need to become a shopping page.

Make your emergency plan before you need it

A good emergency plan can be more useful than buying another piece of equipment.

Know your normal vet’s telephone number.

Know their out-of-hours arrangements.

Know where the nearest emergency veterinary provider is.

Keep important medication and medical information accessible.

Make sure your dog’s microchip details are up to date.

Have an emergency contact.

If somebody else cares for your dog, make sure they know what arrangements you want followed.

That is important in my own work too.

When I am responsible for somebody else’s animal, I want the veterinary and emergency arrangements agreed before anything goes wrong.

Learn first aid before the emergency

Reading guides is useful.

Learning first aid before the adrenaline of a real emergency is even better.

My Ofqual Level 3 Canine First Aid qualification does not make me a vet.

It gives me structured training in recognising emergencies, responding within my competence and knowing when veterinary treatment is needed.

I think canine first-aid training is worthwhile for dog owners and especially important for somebody being paid to care for other people’s dogs.

My Why Every Dog Owner Should Learn Canine First Aid guide explains what I think a useful course should cover and the difference between online and practical training.

Why one-to-one walks help me notice changes

One reason I prefer walking dogs individually is that I get to know the dog in front of me.

Over time, I learn their normal pace, stamina, gait, confidence and habits.

I might notice that a dog who normally trots along happily suddenly starts slowing down.

That a dog begins repeatedly licking one paw.

That their breathing looks unusual for the conditions.

That they do not want to jump down from somewhere they normally manage comfortably.

I am not comparing them with six other dogs.

I am comparing them with themselves.

That does not tell me why something has changed.

But sometimes noticing the change is the useful bit.

If necessary I can stop or shorten the walk, contact the owner and seek veterinary advice.

That approach is part of my Solo Dog Walks service and the wider one-household-at-a-time way I work.

Frequently asked questions

What is the most important thing to know about dog first aid?

Know what is normal for your dog, notice when something changes, prevent the situation becoming worse and recognise when veterinary help is needed.

You do not need to diagnose the cause yourself.

What does a well dog look like?

There is no single picture that fits every dog.

Look at the whole individual: physical health, appetite, drinking, toileting, body condition, comfortable movement, sleep, exercise, enrichment, behaviour and emotional wellbeing.

The key is understanding what normal looks like for that particular dog.

When should I call the vet immediately?

Serious breathing difficulties, collapse, heavy bleeding, repeated or prolonged seizures, severe pain, inability to pass urine, repeated retching with a swollen abdomen, significant trauma, suspected poisoning and heatstroke are among the situations where I would seek urgent veterinary help.

My dog ate a cigarette butt but looks normal. Should I still call the vet?

Yes.

Contact your vet or Animal PoisonLine after suspected nicotine exposure even if your dog currently appears well. Product strength and the amount swallowed vary, and signs can develop quickly. You can also read my guide on my dog ate a cigarette butt

Should I make my dog sick if they ate something poisonous?

No, unless a veterinary professional specifically tells you to.

Trying to induce vomiting at home can cause additional harm

Should I gradually cool a dog with heatstroke?

Current veterinary guidance is to start effective cooling straight away. PDSA guidance says cold tap water is suitable. Do not cover the dog with a wet towel. PDSA

Should I remove glass or another object from a wound?

Do not pull out an object that is embedded in a significant wound.

Contact your vet.

Should I remove something from my dog’s eye?

Do not poke around or attempt to remove a foreign object from the eye yourself. Veterinary guidance warns that doing so can damage the eye surface. PDSA

Is every limp an emergency?

No.

But a sudden limp is information.

Stop strenuous exercise, look for an obvious external problem if you can do so calmly and safely, and contact your vet if the dog is very painful, cannot bear weight, has suffered trauma, or the problem persists or worsens.

Do dog owners need a canine first-aid course?

I think learning canine first aid is worthwhile.

It can help you recognise emergencies, understand your limitations and respond more calmly while professional help is arranged.

A calm approach to dog health

You do not need to spend every day looking for something wrong with your dog.

Get to know them when they are well.

Know how they normally move.

Notice how they eat, sleep, drink and behave.

Understand what they enjoy and what they find difficult.

Check them after walks.

Keep useful emergency information accessible.

Learn some first aid before you need it.

Then when something changes, you have something meaningful to compare it with.

Know normal.

Notice change.

Act when necessary.

And when the situation is beyond first aid, involve the vet.
