First Aid for Horses: What To Do Before the Vet Arrives

By Dr Duncan Houston

A calm, practical guide to handling wounds, colic, eye injuries, hoof punctures, heat stress, and other common horse emergencies safely.

Horse first aid is not about replacing your vet. It is about doing the right simple things in the first few minutes so you do not accidentally make the problem worse.

That matters because horse emergencies are often messy, emotional, and inconveniently timed. A horse cuts a leg on a fence. A hoof lands on a nail. An eye starts streaming tears. A horse lies down with colic signs. On a trail ride, you may be dealing with pain, bleeding, weather, distance, and a 500 kg animal that has not read the first aid manual.

The best first aid is calm, simple, and boring. Keep the horse safe, call your vet early, control bleeding, avoid risky products, collect useful information, and know which situations are urgent.

Quick Answer

Horse first aid should focus on safety, calling your vet early, controlling bleeding with steady pressure, protecting wounds from contamination, recording vital signs, and avoiding medications or topical products unless your vet directs you. Eye injuries, hoof punctures, severe bleeding, colic, non-weight-bearing lameness, wounds near joints, neurological signs, and any horse that is dull, collapsed, or struggling to breathe should be treated as urgent. AAEP emergency guidance recommends keeping your vet’s contact details, referral route, helper contacts, and a stocked first aid kit ready before an emergency happens. (Wayne SWCD)

The First Rule of Horse First Aid

The first rule is not “do something”.

The first rule is: do not get yourself injured.

A frightened or painful horse can kick, strike, pull back, fall, bolt, or crush a handler without meaning to. Before you treat the wound, check the scene. Is the horse caught in wire? Is there broken fencing? Is the horse cast? Is traffic nearby? Is another horse loose? Is the horse panicking?

If the situation is unsafe, step back and call for help. You cannot help your horse if you become the second patient.

What First Aid Can and Cannot Do

First aid can help you:

First aid can help with	Why it matters
Keeping the horse calm	Reduces further injury
Moving the horse only if safe	Prevents worsening trauma
Calling the vet early	Speeds proper care
Controlling bleeding	Reduces blood loss
Covering wounds	Reduces contamination
Recording vital signs	Helps triage urgency
Preventing rubbing or rolling	Reduces injury progression
Preparing for transport	Saves time if referral is needed

First aid cannot replace diagnosis, sedation, nerve blocks, imaging, suturing, joint or tendon sheath assessment, systemic treatment, or hospital care.

The mistake I see most often is not that owners do nothing. It is that they do too much before the vet has seen the horse: sprays, powders, ointments, leftover medications, deep cleaning, pulling foreign bodies, or walking a horse that should not be walked.

How Worried Should You Be?

Risk level	What it looks like	What it likely means	What to do
Low concern	Small superficial scrape, horse bright, sound, eating, normal breathing, no swelling	Minor skin injury or irritation	Clean gently, monitor, and ask your vet if unsure
Moderate concern	Deeper cut, mild lameness, swelling, mild colic signs, mild heat stress, or symptoms lasting more than a few hours	Needs guidance and likely examination	Call your vet for advice and send photos or videos if useful
High concern	Wound near a joint, lower leg wound, puncture, eye injury, hoof injury, colic signs, fever, significant lameness, or worsening pain	Potentially serious emergency	Call your vet promptly
Critical	Severe bleeding, non-weight-bearing lameness, embedded nail, severe colic, collapse, seizures, paralysis, breathing difficulty, severe eye pain, or inability to rise	Life-threatening or sight-threatening emergency	Call your vet immediately and prepare for urgent care or referral

The decision checkpoint is simple: if the horse is painful, lame, bleeding heavily, unable to stand, struggling to breathe, showing colic signs, or has an eye or hoof puncture injury, do not wait.

Know Your Horse’s Normal Vital Signs

A first aid plan is stronger if you know your horse’s normal temperature, pulse, and respiratory rate before an emergency.

AAEP emergency guidance lists typical adult horse values as a pulse of 30 to 42 beats per minute, respiratory rate of 12 to 20 breaths per minute, and rectal temperature of 99.5°F to 101.5°F, which is approximately 37.5°C to 38.6°C. The same guidance advises contacting your veterinarian immediately if temperature exceeds 102.5°F, which is approximately 39.2°C. (Wayne SWCD)

Vital sign	Typical adult range	Why it matters
Temperature	37.5°C to 38.6°C, or 99.5°F to 101.5°F	Fever, heat stress, infection
Heart rate	30 to 42 beats per minute	Pain, shock, dehydration, colic severity
Respiratory rate	12 to 20 breaths per minute	Pain, fever, respiratory disease, shock
Gum colour	Pale pink	Circulation and oxygenation clues
Capillary refill time	Around 2 seconds or less	Perfusion clue
Attitude	Bright and responsive	Dullness often increases urgency

Write your horse’s normal values on a card in the first aid kit. During an emergency, your brain may briefly turn into wet cardboard. Written notes are your friend.

What To Do in the First 5 Minutes

1. Make the area safe

Remove other horses if needed. Keep people clear. Avoid crowding the injured horse.

2. Catch and calm the horse if safe

Use a halter and lead if the horse can be handled safely. Do not fight a panicking horse.

3. Call your vet early

You do not need a perfect diagnosis before calling. Your vet can help you decide what to do next.

4. Get help

One person should hold the horse. One person can call the vet, retrieve the kit, take photos, or open gates.

5. Check the basics

Look at breathing, attitude, bleeding, lameness, and whether the horse can stand.

6. Do only simple first aid

Control bleeding. Cover wounds. Keep the horse still. Avoid medications unless your vet tells you.

AAEP emergency guidance recommends keeping the horse calm, moving them to a safe area if possible, getting help, notifying the veterinarian immediately, and avoiding drugs or tranquilizers unless directed by the vet. (Wayne SWCD)

Cuts and Bleeding: What Should You Do?

Bleeding looks dramatic, but most horse wounds do not cause fatal blood loss. The goal is to control bleeding without contaminating the wound or damaging tissue.

If the wound is actively bleeding:

Step	What to do
Apply steady pressure	Use sterile gauze, a clean towel, or a clean pad
Hold pressure continuously	Do not keep lifting the pad to check
Add more layers if soaked	Do not remove the first pad if bleeding continues
Use a pressure bandage if on a limb	Padding first, then a wrap firm enough to hold pressure
Call your vet	Especially for heavy bleeding, lower limb wounds, or full-thickness cuts

University of Illinois veterinary guidance recommends using a compress and bandage to apply pressure to bleeding wounds, and notes that wounds near joints, leg wounds, neck or head wounds, and penetrating wounds should be evaluated by a veterinarian. (Veterinary Medicine at Illinois)

When does a wound need a vet?

Call your vet if:

Wound sign	Why it matters
Excessive bleeding	May involve a larger vessel
Full thickness skin penetration	May need sutures or deeper assessment
Wound near or over a joint	Joint infection risk
Wound near a tendon sheath	Tendon sheath infection risk
Underlying structures visible	Deeper involvement possible
Puncture wound	Depth is hard to judge
Lower leg wound below knee or hock	Less soft tissue protection, more important structures
Severe contamination	Higher infection risk
Lameness	Deeper tissue involvement possible
Wound on face, eyelid, genitals, chest, or abdomen	Higher risk location

AAEP emergency guidance specifically lists excessive bleeding, full-thickness wounds, wounds near joints, visible underlying structures, punctures, severe lower limb wounds, and severely contaminated wounds as reasons to call a veterinarian. (Wayne SWCD)

Why Lower Leg Wounds Are Different

A cut on the shoulder and a cut on the cannon bone are not the same risk.

From the knee and hock down, there is less soft tissue protecting tendons, ligaments, joints, bone, and tendon sheaths. A wound that looks “not too bad” can still involve an important structure.

Virginia Tech equine emergency guidance notes that lower limb wounds are more complicated because vital structures such as tendons, ligaments, and synovial structures sit close beneath the skin. Wounds that penetrate a joint or tendon sheath can be difficult to treat, career-ending, or life-threatening, so time matters. (Virginia Tech Vet Med)

The practical rule: if a wound is near a joint, tendon sheath, or below the knee or hock, assume it matters until your vet says otherwise.

What Should You Put on a Horse Wound?

Before your vet sees the wound, less is often better.

Safe first aid usually means:

Usually safer	Avoid unless your vet directs you
Sterile saline or clean water rinse	Hydrogen peroxide
Clean dressing	Caustic sprays
Pressure bandage	Styptic powders
Cold water around the area	Thick ointment before suturing
Photos for your vet	Random antiseptic mixtures
Keeping the horse still	Aggressive scrubbing

AAEP guidance advises not putting anything on a wound except a compress or cold water before veterinary advice, and warns against attempting to remove debris or penetrating objects without veterinary guidance because that can worsen bleeding or damage. (Wayne SWCD)

A wound that might need sutures should not be filled with greasy ointment, powder, or harsh chemical spray. The goal is to preserve the tissue for proper cleaning, assessment, and repair.

Basic Bandaging for a Leg Wound

A temporary bandage should protect the wound and control contamination until veterinary care.

A simple limb bandage usually includes:

Layer	Purpose
Non-stick sterile dressing	Covers the wound
Padding layer	Protects the leg and distributes pressure
Gauze or cling wrap	Holds padding in place
Elastic outer wrap	Secures the bandage
Tape if needed	Prevents slipping

Bandage tension matters. Too loose and it slips. Too tight and it can damage tendons, skin, and circulation.

Check above and below the bandage for swelling, heat, or increasing pain. If you do not know how to bandage safely, apply direct pressure with a clean pad and wait for your vet’s instructions.

Hoof Punctures: Do Not Pull the Nail Without Advice

A nail, wire, screw, or sharp object in the hoof is a veterinary emergency.

The instinct is to pull it out. Often, that is the wrong move.

If the object is still in place and not likely to be driven deeper, leave it there and call your vet. Radiographs can show where the object has gone and whether it is near the coffin joint, navicular bursa, tendon sheath, coffin bone, or deep digital flexor tendon. Merck Veterinary Manual states that, when possible, it is best to leave the object in the foot so radiographs can determine which anatomical structures are involved. (Merck Veterinary Manual)

Situation	What to do
Object embedded and stable	Call your vet, keep horse still, protect object from movement
Object at risk of driving deeper	Call your vet immediately for instructions
Object already removed	Save it, mark entry location if possible, call your vet
Horse very lame	Treat as urgent
Puncture in frog or sole	Treat as urgent because deep structures may be close

Do not soak, dig, pack, or medicate a puncture wound before veterinary advice. A tiny hole can hide a major problem.

Eye Injuries: Treat Them as Urgent

Horse eyes can deteriorate quickly. A watery, squinting, cloudy, swollen, or painful eye is not something to watch for several days.

Call your vet urgently if you see:

Eye sign	Why it matters
Squinting	Usually means pain
Eye held closed	Significant discomfort
Cloudiness or blue haze	Corneal disease, ulcer, uveitis, or glaucoma possible
Excessive tearing	Irritation, ulcer, foreign body, or internal eye disease
Yellow or green discharge	Infection or inflammation
Visible scratch or wound	Corneal or eyelid injury
Swollen eyelids	Trauma, infection, or foreign body
Rubbing the eye	Can worsen corneal damage

Oklahoma State veterinary guidance emphasises that early treatment of horse eye problems is important because delay can increase cost and risk loss of vision, and lists constant squinting, red eye, or cloudy eye as concerning signs. (news.okstate.edu)

First aid for eyes is simple:

Do	Do not
Call your vet	Use old eye ointment
Prevent rubbing	Use steroid drops without an exam
Use a clean fly mask if safe	Apply human eye drops randomly
Flush gently with clean eye wash if debris is obvious	Force the eye open if painful
Take photos	Wait days to see if it clears

The mistake to avoid: using leftover steroid eye medication before the cornea is stained and checked. Steroids can be dangerous if a corneal ulcer is present.

Colic: What Should You Do Before the Vet Arrives?

Colic means abdominal pain. It can be mild, but it can also be life-threatening.

Signs include:

Colic sign	What you may see
Pawing	Mild to moderate pain
Looking at flank	Abdominal discomfort
Repeated lying down and getting up	Pain or restlessness
Rolling	Can indicate more severe pain
Sweating	Pain or distress
Reduced manure	Gut motility problem
Not eating	Common early sign
Stretching or posturing	Abdominal discomfort
Depression	Systemic concern

Oklahoma State veterinary guidance recommends calling your veterinarian for colic, keeping the horse quiet if possible, walking only when needed to prevent rolling or self-trauma, and not giving feed or water while waiting for the vet. (news.okstate.edu)

Should you walk a horse with colic?

Walking can help keep a mildly painful horse from rolling and injuring themselves. It does not cure colic.

Situation	Walking advice
Mild discomfort, horse wants to stand	Short gentle walking may be okay
Horse is calm lying down	Let them rest if safe
Horse is trying to roll violently	Walk if safe to reduce injury risk
Horse is exhausted	Stop walking
Horse is severely painful	Call urgently and follow vet instructions

Do not walk a horse for hours until both of you are exhausted. That turns one emergency into two tired mammals with poor judgement.

Should you give flunixin or phenylbutazone?

Do not give pain medication unless your vet tells you to.

Pain relief can be appropriate, but timing and dose matter. Medication can mask signs, complicate assessment, and create risk if the horse is dehydrated or compromised. Tell your vet exactly what has been given and when.

Heat Stress and Overheating

Heat stress can become serious quickly, especially during transport, humid weather, heavy exercise, or in horses that do not sweat normally.

Signs include:

Sign	Why it matters
High temperature	Heat stress or illness
Flared nostrils	Increased respiratory effort
Lethargy	Systemic stress
Weakness	More serious heat illness
Dehydration	Fluid loss and poor recovery
Little or no sweating in hot weather	Possible anhidrosis
Fast breathing or heart rate	Stress, pain, overheating

Oklahoma State veterinary guidance recommends cooling overheated horses by spraying water over the body, especially the back, inside the legs, and underside of the neck, moving them into shade, using a fan, and offering frequent small drinks rather than allowing rapid unlimited drinking. (news.okstate.edu)

If the horse is dull, weak, collapsing, breathing hard, or has a very high temperature, call your vet urgently.

Severe Lameness or Suspected Fracture

Do not force a severely lame horse to walk.

Call your vet urgently if there is:

Sign	Why it matters
Non-weight-bearing lameness	Fracture, severe abscess, tendon injury, joint infection, or major trauma possible
Limb instability	Possible fracture or ligament failure
Severe swelling	Trauma, infection, or structural damage
Wound over a joint or tendon sheath	Synovial infection risk
Horse cannot rise	Emergency
Sudden severe pain after fall or kick	Fracture or major soft tissue injury possible

If a fracture is possible, movement can turn a repairable injury into an unrecoverable one. Wait for veterinary instructions before moving the horse unless the location is immediately unsafe.

Burns, Scalds, and Chemical Exposure

Minor burns may be cooled with clean running water. Deeper burns, widespread burns, chemical burns, electrical burns, or burns near the eyes, genitals, mouth, or limbs need veterinary care.

Do not apply butter, oils, harsh chemicals, or thick ointments before assessment. Cool, cover with a clean non-stick dressing if possible, and call your vet.

Choke: A Common Emergency Owners Misread

Choke in horses means feed or another material is lodged in the oesophagus. The horse can usually still breathe, but choke can lead to aspiration pneumonia if feed, saliva, or fluid enters the lungs.

Signs include:

Choke sign	What you may see
Feed or saliva from nostrils	Classic concern
Coughing or gagging	Oesophageal obstruction
Neck stretching	Discomfort
Repeated swallowing	Trying to clear blockage
Anxiety or pawing	Distress
Not eating	Obstruction or pain

First aid:

Do	Do not
Remove feed and water	Do not force water into the mouth
Call your vet	Do not massage aggressively
Keep horse calm	Do not give oral medications
Monitor breathing	Do not let the horse eat more
Watch for fever later	Aspiration pneumonia can follow

If choke seems to resolve, still speak to your vet, especially if there is coughing, nasal discharge, fever, or dullness afterward.

What Should Be in a Horse First Aid Kit?

AAEP recommends keeping a first aid kit in a clean, dry, accessible place, making sure barn users know where it is, and keeping another kit in the trailer or towing vehicle, plus a pared-down version for the trail.

A practical horse first aid kit should include:

Item	Why you need it
Vet and referral hospital contacts	Fast decision making
Horse medical information	Medications, allergies, vaccination, insurance
Rectal thermometer with string	Temperature checks
Stethoscope or timer	Heart rate and respiratory rate
Sterile gauze pads	Wound coverage
Non-stick dressings	Wounds that may need sutures
Cotton roll or padding	Limb bandaging
Cling gauze or roll gauze	Holds padding
Elastic cohesive wrap	Secures bandage
Adhesive tape	Bandage finishing
Clean towels	Pressure, cleaning, support
Saline or clean water	Gentle flushing
Gloves	Hygiene and handler protection
Scissors	Cutting bandage material
Flashlight or head torch	Night emergencies
Permanent marker	Mark swelling, nail entry points, times
Hoof pick	Checking soles and frogs
Pliers	Only for use if vet instructs nail removal
Clean bucket or container	Water, cooling, lavage support
Fly mask	Eye protection from rubbing
Notebook or phone notes	Record vitals and timeline

Do not let the first aid kit become the drawer of expired sadness. Check it before travel, competitions, and trail rides.

What Information Should You Give the Vet?

When you call, give clear information fast.

Information	Why it helps
Horse’s name, age, sex, and breed	Basic triage
Location	Vet access and travel time
Main problem	Wound, colic, eye, hoof, lameness, heat stress
Time it started	Urgency and progression
Vital signs	Temperature, heart rate, breathing rate
Pain level	Mild, moderate, severe, rolling, non-weight-bearing
Photos or videos	Helps triage before arrival
Medications already given	Avoids dangerous duplication
Vaccination status	Especially tetanus
Recent travel, feed changes, injury, breeding, or illness	Helps identify cause
Whether transport is possible	Referral planning

The more accurate the information, the better your vet can guide you.

When Is This an Emergency?

Call your vet urgently if your horse has:

Emergency sign	Why it matters
Severe bleeding	Blood loss or vessel injury
Wound near joint or tendon sheath	Deep infection risk
Puncture wound	Depth may be hidden
Embedded nail or sharp object in hoof	Deep structure risk
Eye injury, squinting, or cloudiness	Sight-threatening
Severe colic signs	Surgical or life-threatening disease possible
Non-weight-bearing lameness	Serious foot, limb, or structural injury
Difficulty breathing	Respiratory emergency
Collapse or inability to rise	Critical
Seizures, paralysis, or neurological signs	Emergency
Fever with depression	Infection or systemic illness
Severe heat stress	Organ and neurological risk
Choke with distress or nasal feed discharge	Aspiration risk
Foaling difficulty	Time-sensitive emergency

AAEP emergency guidance also states that horses with lameness, reluctance to move, pain, unwillingness to rise, bleeding, swelling, seizures, paralysis, or tying up signs should be treated seriously, with prompt veterinary communication. (Wayne SWCD)

What To Do Right Now in the Most Common Emergencies

Emergency	First action	Do not do
Bleeding wound	Apply steady pressure and call vet	Do not remove clots repeatedly
Lower leg cut	Cover, bandage if safe, call vet	Do not assume it is superficial
Hoof puncture	Keep horse still, call vet, leave object if possible	Do not pull deep nails before advice
Eye injury	Prevent rubbing, call vet	Do not use old ointment
Colic	Call vet, check vitals, remove feed	Do not medicate without advice
Choke	Remove feed and water, call vet	Do not force water
Heat stress	Cool with water, shade, fan, call if severe	Do not delay if weak or collapsed
Severe lameness	Keep still, call vet	Do not force walking
Suspected fracture	Keep calm and still	Do not move unless unsafe
Burn	Cool with clean water and cover	Do not apply oils or harsh products

Common Mistakes Owners Make

Mistake 1: Waiting too long to call the vet

Calling does not mean you have failed. It means you are using the right person early.

Mistake 2: Using leftover medication

Pain relief, sedatives, antibiotics, and eye medications can change examination findings or cause harm if used incorrectly.

Mistake 3: Pulling out nails from the hoof

A hoof puncture needs location and depth assessment. Removing the object too early can make the tract harder to identify. (Merck Veterinary Manual)

Mistake 4: Spraying everything in the first aid cupboard onto a wound

Many sprays and powders irritate tissue, contaminate the wound, or interfere with suturing.

Mistake 5: Over-walking colic

Walking can prevent rolling injury, but exhausted walking does not fix the gut.

Mistake 6: Ignoring eye signs

A squinting horse eye is painful until proven otherwise.

Mistake 7: Not checking tetanus status

Lacerations and puncture wounds often require tetanus review. AAEP emergency guidance states horses treated for lacerations or puncture wounds require tetanus booster consideration. (Wayne SWCD)

Mistake 8: Forgetting the horse is dangerous when painful

Even kind horses can kick, strike, or panic when injured.

How To Prevent Common Horse Emergencies

You cannot prevent every emergency. Horses are elite-level chaos wrapped in beautiful hair. But you can reduce risk.

Prevention step	Why it helps
Inspect fences, gates, and stables	Reduces cuts, entrapment, and hoof injuries
Remove wire, nails, sharp metal, and broken boards	Prevents lacerations and punctures
Keep first aid kits stocked	Saves time
Know your vet’s emergency process	Avoids panic
Keep vaccination records current	Tetanus protection matters
Check horses daily	Finds wounds before infection
Store feed safely	Reduces colic and choke risks
Make diet changes gradually	Reduces digestive upset
Provide clean water	Supports gut and whole-body health
Maintain hoof care	Reduces cracks, puncture complications, and lameness
Use safe trail tack and carry basics	Reduces trail risk
Train handlers in first aid	Makes emergencies less chaotic
Practice loading	Helps if referral is needed
Keep horses fit for the work asked	Reduces heat and fatigue risk

AAEP emergency guidance recommends knowing the referral route, storing emergency contacts, preparing first aid kits, and evaluating the horse’s environment to remove hazards before emergencies occur.

Normal Concern vs Red Flag Emergency

More reassuring	More concerning
Small superficial scrape	Full-thickness wound
Horse sound and bright	Lame, dull, or painful
No swelling	Rapid swelling or heat
No bleeding	Persistent or heavy bleeding
No eye pain	Squinting, tearing, or cloudy eye
Mild colic signs that settle quickly after vet advice	Rolling, sweating, repeated pain, high heart rate
Minor hoof chip	Nail, puncture, exposed tissue, or severe lameness
Normal temperature	Fever or heat stress
Eating normally	Off feed with pain or depression

The real question is not “does this look dramatic?”
It is: could this involve pain, infection, deep structures, vision, breathing, circulation, or gut compromise?

Will My Horse Be Okay?

Many horse emergencies have good outcomes when owners stay calm, act early, and avoid harmful first aid.

The outlook is better when:

Good sign	Why it helps
Vet is called early	Treatment starts sooner
Horse remains calm and standing	Safer handling and lower trauma risk
Bleeding is controlled	Less blood loss
Wound is protected	Less contamination
No deep structures are involved	Simpler recovery
Eye problems are seen quickly	Better vision outcomes
Colic is assessed early	More options before deterioration
Hoof punctures are imaged	Better treatment planning
Tetanus status is current	Lower preventable risk

The outlook becomes more guarded with delayed care, severe blood loss, deep joint or tendon sheath wounds, severe colic, non-weight-bearing lameness, embedded hoof punctures, eye ulcers, respiratory distress, collapse, or uncontrolled pain.

FAQs About Horse First Aid

What is the most important thing in horse first aid?

The most important thing is safety, followed by calling your vet early. Keep the horse calm, protect yourself, control severe bleeding, avoid unnecessary medications or products, and collect useful information such as vital signs and photos.

Can I give pain relief before the vet arrives?

Only if your vet tells you to. Pain medications can mask signs, affect examination findings, and may be risky in dehydrated or systemically unwell horses.

Should I clean a horse wound before the vet sees it?

For simple superficial wounds, gentle rinsing with clean water or saline may be reasonable. For deep wounds, heavily bleeding wounds, punctures, wounds near joints, or wounds with foreign material, call your vet first and avoid aggressive cleaning.

Should I remove a nail from my horse’s hoof?

Usually no, not until your vet advises you. If possible, leave the object in place so radiographs can show the path and which structures may be involved. If it must be removed for safety, save the object and mark the entry point. (Merck Veterinary Manual)

Is every eye injury an emergency?

In horses, eye pain, squinting, cloudiness, swelling, or visible injury should be treated as urgent. Do not use old eye ointment, especially steroid-containing medication, unless your vet has examined the eye.

The Bottom Line

Good horse first aid is calm, simple, and veterinary-led.

Your job is not to diagnose everything in the stable aisle. Your job is to keep the horse and people safe, call your vet early, control bleeding with pressure, protect wounds from contamination, avoid risky medications or products, and provide clear information.

The safest rule is this: when in doubt, call the vet before you do more. That is especially true for eye injuries, hoof punctures, colic, lower limb wounds, wounds near joints, severe bleeding, severe lameness, collapse, breathing difficulty, fever, and neurological signs.

First aid buys time. Veterinary care solves the problem.
